Calmag and Epsom reacts and precipitates out when mixed.

Jip. Thats why when feeding Calmag, i never mix it with anything. 

[S33dFr33k]

thanks for the info guys. I flushed today with plain water.

looks like possible ph issue to me, what are you pHing to and what are you using to measure it with?

Just a question, not knocking. 

Why would you mix Epsom salts, with CalMag? Since the latter is a mix of the 2, you already have Magnesium in the Calcium mix.

Though I agree with your comment of them causing precipitation, there seems to be some missing information and a good discussion possibly.

I looked over the thread, you havent got a issue at the moment, the plant is actually happy, and you have already fixed the issue with the Magnesium Sulfate.

The plant is happy in my eyes, and you not going to see a full turn of health, due to the old spots on old leaves being done and will not recover. 

Your new growth is great and will improve, so stay away from changes now and dont fix anything.

i have a dislike for the granule calmag mixes... they are mixed not mixed in a 1:1 ratio more like a 5:3 ratio, but using the scoop to measure out always leads to the incorrect ratio of calmag. that's why i prefer the liquid calmag... but it is a lot pricier than the granules. or even a hybrid approach where the calcuim nitrate is separate from the magnesium sulphate and you can add them separately or together in the correct ratios which is 2:1, two parts calcuim nitrate, one part magnesium sulphate

Yes

Added, having to be careful using the nitrate too, as it will need a reduced N in the nutrients schedule when being used.

Calcium and sulphur fall out of suspension when you mix them. The white precipitate is gypsum.

Cal mag is mixture of calcium nitrate and magnesium nitrate. There's no Epsom salts in calmag.

Correct, my understanding is that he is adding Epsom, for the benefit of the Magnesium, not the sulfate. 

Thanks for adding to the explanation and helping the understanding.

Just a tidbit of info for the OP, dont mix the two, 'shotgun' remedies may do more harm than good. Years back I was a noob and made that mistake, so speak from personal experience.

Hey me easy crew! Got a bit of strange thing happening here. Leaves going light green towards to outer leaf and dark on the inner leaf. 

Last feed was only CalMag and Epson in ph6 water. 

Any ideas? 

I'm thinking root zone, maybe too warm from the heat matt? 

Nitrogen toxicity.

pHing to 6 and using a pH meter. I re-calibrated it before the last plain water feed.

to be totally honest....n00b mistake. I just didn't know. I've only been doing this for a year and half so still learning and kinda just following advice from all over the place. Growing cannabis was my lock down hobby which has got me hooked.

My other grow mates say give CalMag with every feed and then Epsom does such wonders, so I added it. I should just stick to my old routine of giving Epsom with plain pHed water twice a week. So as @Bos said. more of a shotgun remedy to try get things to move on quicker.

But you are spot on. All three plants are doing great at the moment, actually thriving and I've seen a good push in size. Will post pics later, its night time in the tent currently.

[The_StonedTrooper]

Perfect, as much as I was against using them together, I didnt at all say that you shouldn't use Epsom salt.

The stuff has its place and I've often used it, when needed.

Growing in organic, being a salt, it will kill off some microbes. So be sure to inoculate with them.

Quick update on the ladies. All looking very happy. The yellow colour is fading now. 

I think I'll look at topping two of them next week. 

[420SA]

I reckon you can top right now. Looks like you have enough nodes on at least T1 and T2. Flip deadline is 3 July which is not too long from now

[The_StonedTrooper]

Agree with the above, 

Snap your fingers, next thing you know, its D Day

[S33dFr33k]

Update on the ladies. I topped T1 and T2 on Sunday night. I think I'll let T3 just go with the flow. 

Both are looking good with no signs of stress after topping. 

These pics were taken at 7pm last night.

interesting leaf deficiency.

 

what are you feeding them and how much?

I'm feeding them Budding Genius range. Currently feeding the following in veg:

Phytogrow: derived from marine extracts, fish hydrolysate, kelp and bees wax. 2.5ml-1l

Set The Stage: organic acids, earthworm exudate, natural occurring nitrogen, micro nutrients, Auxins, cytokines, chitinase. Potassium and phosphorus. 5ml-1l

Cannamag: Calcium and Magnesium. 1.5ml-1l

Gold Brix: derived from amino acids, sugar cane molasses, natural extracts containing Auxins and carbon. 2ml-1l

Take Up: derived from fine mined leonardite, natural extracts, potassium, phosphorus. 2.5ml-1l

I mix it all in 4l of filtered water and set the PH to 6.

Im only watering when the medium is dry on the top and bags feel light.

Seems your method isnt the fault in the mix.

i actually tried to find addition info about the problem you have...and it was really hard!!! i think you have a few problems tho... 

1) the yellowing of the lower leaves like that... the closest i can find is a zinc deficiency

2) but zinc deficiency alone doesn't make sense, the very dark inners of the leaves potentially indicate a nitrogen toxicity

3) and the only other thing it could be is a deficiency in potassium , but i don't see the usual spotting on the leaves.

zinc is a tough one to identify because many other elements in an imbalance can cause a zinc lockout. zinc starts off at the bottom of the plant and works its way up, so using new growth may not be a good way to judge plant health in this case.

has has the problem gone? is it spreading or getting worse, or do you think you have made it through whatever bad vibes you going through?

another thing is do you shake your bottles before you use them? the nutrients will loosely separate if left undisturbed and you may find you are not getting a smooth ratio of nutes per dose

[The_StonedTrooper]

I'd often get that same yellowing, and as soon as I would add Epsom salts, it would get better, but as you see above, the damage is done and not going to fully recover on the old leaves. 

It almost like balances the nutrients and let's the roots take up better, 

Is very weird as you say @CreXand I dont understand it fully myself, but as above, that seems to help, or remedy.

It's definitely not getting worse. I think it caused some damage and now we're moving on. 

Yip, I do shake the nutrient bottles up before the feed. 

Here's some pics from today without the light on. 

 

[CreX]

Lol it looks like you are growing an entirely different plant with the yellow tips hehe... The rest of the plant, actually even including those leaves look healthy and happy...
