So we got a decent qoute for foam spray insulation. People insulation doesnt come cheap at all even my calculations to diy with isowall panels ended up breaking the budget..but okay still cheaper over the next few years than buying large led fixtures. Stuff has been arriving in the mail. The outlet manifold of the nft is done. Water pump is in and air pump came yesterday but without any silicon tubes so i need to run in tomorrow for that. just installed two smoke alarms as well. Basically only waiting onthe moulded net pots made spicifically for 110mm gro tubes. In 20 rockwool cubes im germinating some seeds. I had the e-m seeds collection from biltong n budz in cart but found out totemic has some bobbys widow x gorilla cookies f2 in stock so i went that route instead. First ones should pop tomorrow Doing 18 of them in hydro and 7 in soil for growth comparison. Ill post those pics and the finished nft when final holes are drilled and pots inserted.

We're 39 days since germination. Growth is strong but a tad off, where the new growth is quite pale and some of the fingers become inverted so that part of the finger is turned upside down. It looks rather spindly. They eventually grow into good looking but skinny leaves. Many leaves lower down end in a curled Claw. This is apparently due to me using nutrient-enriched soil as well as "salt nutrients" resulting in nutrient toxicity. Anyway I took some photos. They're perfectly good plants just need a bit more attention

I started off with the salt based nutes. Rather expensive but the plants ended up decent. My last 2 grows i went the homemade supersoil route and not looking back at all. Way less maintenance and zero deficiencies plus ive got some cash to spare on genetics. Also take into account that ive only grown outdoor.

Depends what soil you are using. Some can go a few weeks without much in the need of nutrients. People grow successfully with mineral based nutrients in soil all the time. You flush soil after the harvest before next grow.

Hi all as the title says I've been dealing with cases of The Claw, or Nitrogen Toxicity I believe. The plants have always harvested fine though I suspect they weren't at the highest quality they could be for this clawing reason. Growing medium: soil - Freedom Farms Premium Classic Nutrients: Terra Aquatica 3 Part Flora series (Micro, Grow, Bloom), Kushy brand Cal-Mag granules supplement. I use a generic pH down solution to pH the water. I am currently working on a 60% strength dilution already which makes the nutrient toxicity so puzzling. The N-P-K of each: Micro: 5-0-1 Grow: 3-1-6 Bloom: 0-5-4 Have I missed any info? I've attached images of my nutrient solution chart and leaves of the plants. Thanks all for your time trying to help me out.

Man on a mission!

I've only ever grown this way, so I appreciate all the knowledge being shared, thank you. What I'm going to do: I'm going to feed straight pH'd water for 5 feeds. Then I'll resume feeding with a 20% diluted nutrient solution. Maybe I'll be able to uncurl the clawed leaves a little, I don't know I guess I'll see. In the meantime while I try salvage the grow I'll be doing more research on the correct growing medium for me and the supplements that need to go with them. Coco has always interested me. Am I missing anything else important? Probably haha. Also now's a good a time as ever to do a grow diary, so I'll do that too and we'll see where the grow goes

This is why I suggested maybe finishing the grow as is. I don't know how well it will go trying to reestablish the soil microbiology midway through veg. If I was truly desperate I'd clone what I can and start fresh, I've been forced to do it before. I stand by my original suggestion of finishing up the current grow as is with the salt nutes and then making fresh changes for the upcoming grow.

There is hardy anything to add... the generic pH solution you used was most likely chemical... what sets all you used to chemical and kills your micro organisms. With FF stick to biological fertilizer parts only and skip any pH tests. Or go Coco/Hydro and stick to salts and chemicals only and use generic pH to get it in the right region. BioBizz still costs a bit and one drop of chemical pH down will render the biological advantage obsolete. To get some flora back, Biodyne Environoc 401.. micro organisms in liquid form.. get a small bottle and add accordingly. Keep chemicals out of soil.. ruins most of the positive effects to grow in soil. If you use fertilizers killing living things.. stick to coco, rock wool or DWC.

Its a risk imo. Even though they are still in veg, changing nutes mid grow is generally a disaster. You could give the medium a real good flush and just give plain water until the plants start looking hungry, then switch to biobizz range.

Plants just don't look healthy and it makes me sad. It's still early on and I'd like to be proactive if at all possible without being hasty

pH adjusted to as close to 6 as possible

They were germinated on the 13th Jan 2023 so they are currently only 39 days old. Still need to fill out the scrog so it will be a short while til flower. If I'm able, would you recommend I plain water for 2 - 3 waterings, and then switch to a mix of BioBizz nutrients? I've found a feeding schedule for Biobizz nutes specifically for Freedom Farms soil. Plus the price of the Biobizz nutes was surprisingly lower than I expected, and I believe switching nutes is an option.

Also, what are you adjusting your pH to? Salts in coco usually needs adjust to 5.8, organics is 6.2. If you switch to organic nutes the need to pH will also fall away. FF premium buffers its own pH at 6.2-6.5

I wouldn't change anything on this grow. You have mentioned you've done three grows already so I would just finish up the current one and make changes on the next. Don't lower your salt feed, I don't think that's necessary. There's a chance the salt nutrients have already disrupted the microbiology within the soil already to the point that your plants are only feeding off the salt nutrients. I think you will quickly find that switching to coco will be much, much more affordable than switching to liquid organic nutrients.

Yes FF premium classic is an amended soil and has enough nutrients to sustain a vegging plant for more than a month. By adding salt nutrients you are overloading the soil. The Biobizz range works well with FF premium. Changing anything for this grow will likely mess it all up. What you can do is to stop with the calmag and the Nitrogen. Just give plain water for 2 or 3 waterings. You far into flower are you?

@Totemic@Ill_Evan Damn, always surprises me how little I actually know about growing cannabis. Are you guys basically saying that there are nutrients already in the soil which are being taken up by the plants along with the salt nutrients and this is causing a nutrient toxicity? I'm pretty strapped for cash at the moment, and switching them over to coco isn't an option (they're already established in the soil). Are brand new, organic nutrients absolutely necessary or can I just tone down the amount of salt nutrients I'm using until I can afford organic nutes? Let's say a 20% dilution? Could you perhaps drop me a brand of tried and tested organic nutes that I can go do my own research on? To me it sounds like organic nutes are the right way to go so I might just bite the bullet. What confuses me as well is that there is a recommended dilution ratio for Soil on the side of the Tera Aquatica nute bottles.

It could be an expression of that specific strain. I do note that you are using what is considered an "organic soil" but also using salt nutrients. In my opinion there could be a bunch of stuff in that soil that doesn't end up getting used because your plants will most likely just use the salt nutes you provide. I see @Totemic ninja'd me on that note

Those are mineral salt nutrients you are using in an organic medium. It is going to do this every time. Either switch to plain coco/perlite and continue on the nutes you have for your next grow, or change your nutes to organic ones

Yes they are 4 Blue Dream photoperiod plants. By Atlas Seeds I believe.

I will definitely go have a look at the Korean natural farming for some tips and I'll make sure I carry on with my fish emulsion as well

what is up 420fam! as it is almost such time i'm taking a toke break and updating the thread. everything i got thus far is from a local hardware not a km from me, i couldn't believe it was convinced i need to go into town, which i wasn't keen on tbh. in any case the pictures will tell the story but ill mention details. completed about 60% of the support frame. completed 90% of the 110mm tubes. attached castor wheels to base and it glides around like a cloud. need to run into the hardware shop to swop out some unneccessary stuff and replace with things i didn't know we need. edit: uhm yah so the camera, its an old samsung galaxy under hps lighting, its not working well due to screen breaks i have no other option other than to use this one or bother fiance for hers which i dislike to do. so sorry about to trash pics. and please ignore the wall, running 1200mm mylar diamond pattern across all of it as the build progresses.
