@CreX rates even 350ppm is aight. Plus it's just short of the recommended dosage by Nutriplex. If not, I'll wait and let my plants tell me they need more nutes. Ppm might be 1995, but quick maths is 2019. 400 ppm is 0.8 EC according to the manufacturer of my EC pen.

This is awesome. Something like this is what would push me towards wanting to learn coding in general. Very awesome stuff @Trailblazer420 and @SuMi

Doesn't seem like anything to worry about right now. Just keep an eye on it and if anything worsens or spreads, let us know. Probably is just the nute spill as stated by @SkunkPharm

Jissis here we go, here we go

Rate the plants are looking peachy Just added in the nutes, some EM Pro Soil and Cal Mag. Going to let them continue to do their thing and update as they go pH 5.5, 400ppm, 3/4 strength nutes Lefty Righty

This is the first I've heard of any store bought soil that's unusable indoors

After a good amount of time now with growing with DWC I am beginning to see that changing the res is beneficial if not essential. I am going to experiment with more occasional res changes and note the results. I may have gotten very lucky up until now Keep the suggestions coming my dude we are here to share and learn.

Awe kewl, so if I had kept the res as is I could've just added micro, but since I've done a res change I'm going to start on just below the recommended dosage and treat that as the max. So for my 7.5 litre res each I am going to add 4ml of Nutriplex micro, gro and bloom. That should keep it just below max dosage. I do keep my water overnight before adding to the res, but when I did the res change now I just filled them straight from the hose. Had to balance the res once every few hours to get it to stabalise but it's good now. Awe @greenkush. I initially thought nitrogen toxicity but the way I've been adding nutes, lockout and high pH are the clear issues I had. I've now got a very good idea of how high a dose this particular strain can take. Second time growing this strain specifically. @PsyCLown hydrogen peroxide was something I read into when I first researched into DWC, but I decided that if I could manage the res water well enough I could avoid having to use it and since the coming of @CreX and his ultimate knowledge on teas I am now convinced one does not really need it unless in a root rot emergency. I think if you add the right bacterias to your res you can avoid the majority of the nasties.

@CreX thanks for the clarification, I must've misunderstood the material I read about it while researching whether changing my res every week was necessary Lockout I can also agree with. I think either way a res change was needed pH was at 6.4 and ppm was at 700. Recently found out 700 ppm is 1.4 EC You rate just micro to pH water will last me to switch? I'm willing to try it Added Epson salts right in the beginning but I will be picking up some proper cal-mag on Tuesday and using that

Wasn't liking the new growth I was seeing from the plant on the right, plant on left is also displaying similar but less severe symptoms of "leaf clawing" as to the plant on the right. The leaves themselves feel almost brittle in a sense, as though over-dried. Initial research points towards nitrogen toxicity. I've decided to flush the res and let sit in pH'd water overnight. Will add half dose of nutes tomorrow.

EC and pH pen my best investment DWC wise. Agreed with @Mambawana

In my current grow diary I haven't changed my res once yet I will only change my res when I switch to flower

I like to vary my pH between 5.5 and 6.5 during my grow, but the pH swings being described here sound outter-worldly to me, coming from only changing my res once during an entire grow with no issues

I've never experienced such that sounds nuts to have to constantly balance your pH

@PsyCLown and @CreX let's chip in bois, charge some plebs to measure their light's ppfd

My brand is "@PsyCLown DIY", probably the most trusted brand on this whole forum

Interesting so us using those lux meters on our phones isn't going to give us too accurate information If only there were cheap or even easily accessible ppfd meters.. us boys just gotta trial and error like real hobbyists

Scrog rack that's brilliant. Nice emergency DIY!

Fantastic work and very awesome pics

@PsyCLown my reses are small enough that I just pop the cooler top open and shift the bottom enough to form a gap to pour in new res water. I have done two full grows with only changing the res at switch to flower, so when I do the full res change I just use a bucket the same height as my cooler boxes and pop the roots with some water in there with the cooler box lid suspended by the rim of the bucket. @CleanGreen initially I was max paranoid about root rot but I've found that as long as the res water doesn't go above 26C and there is no light leaks into the res you should be A ok the root system develops beneficial microbacteria by itself and too frequent res changes could actually hamper these bacteria from fighting off the bad bacteria that causes root rot. Just my experience, but one cannot prevent everything all the time

@CleanGreen you know I'm about that DIY unfortunately I don't live by myself and my current allocated grow space is limited to just the one tent for now. It was a bit of a discussion just to have the space I do have but I am hoping that once this current grow is completed I can leverage some more space. Trust I'd have an Omega level grow room if it were completely up to me

I've followed your grows since you started on the forum @CleanGreen always pushing your space's limits and once growing past your lights if anyone has learnt about space management it is you sir! I am hoping with the scrog I can avoid a miniature cannabis botanical garden (although it does sound kinda nice...) I'll be happy with another tent to do perpetual grows with one in veg and the other in flower, but alas, we must wait for that day

Ah man, just can't catch a day now without doing something with the plants Growth is so rapid I have to check daily to tuck new growth under the scrog net to keep it nice and level. It will be super worth it when the whole scrog is filled nicely and evenly Bumped up the watts to 120W and keeping it just about 40cm above the canopy Also did a defoliation of the large fan leaves tonight

A very exciting update! With the aide of our very own @PsyCLown I was provided with a DIY quantum board kit consisting of two QB288's capable of 240W of light goodness. A shout out to @CreX who also assisted me in troubleshooting the setup when I ran into some initial issues with the driver. Here is how the new setup looks: Now for the plants. Just a quick photo update should suffice. Starting to fill up the scrog net consistently. Going to run the QB at 100W for now while I am still in veg and testing the setup.
