New Grower Any help understanding these symptoms would be appreciated

[Lupercal]

Hi there, I am having this problem with my plant and I have researched lots, tried things but to no avail, she remains sickly looking

She has been grown according to this afn guide https://www.autoflower.org/threads/greenjeans-dwc-method.52951/

Seedsman strawberry cheesecake auto. In her 10th week. Temps have been within range, humidity also within range. Slight browning of the roots but no smell and no slime. Good air pump volume in non-recirculating dwc bucket. 18 on 6 off Schedule for Spider Farmer sf2000 light.

The browning started around pre flower, the nutes are the same brand (flora dual part synthetic), with silver bullet used at mild strength.

The ph has been pretty much fine, one week it did randomly drop loads but i fixed that pretty quick

I have bumped up the feed (including calmag) to 2/3 strength compared to the dose a photoperiod would have a week ago up from 1/2, Symptoms seem to persist but have not accelerated so I am doubtful the feed is too strong. Started out light and slowly worked up to this with weekly changes of feed.

Anything else I haven't covered please ask

First off welcome to AFN @Lupercal I grow in coco using megacrop and also grow using TLS and top dressing only NO experience with your nute line... That being said It looks like too much nitrogen causing the clawing making the leaves really dark green/waxy... Which will also cause a lockout of calcium and potassium hope that helps

This has helped me considerably learning how to feed my plants:

Tutorial - A word on Nutrients

The proper use of “salt” based fertilizer to grow Auto Flowering Cannabis. Salts: Natural and man made any chemical compound formed from the reaction of an acid with a base, with all or part of the hydrogen of the acid replaced by a metal or other cation. Learning how to use salt based...

Too much...
of something, food, light or both.
Too green, which your plants are, means too much fertilizer.
Yellow tips can be either too much food or light.

I'd reduce food and light for a few days, and see what happens.
Even if that's wrong, too little food/light for a few days will do little harm.

Too much N and adding calmag may just compound the issue. I dont see a magnesium deficiency? Are you using a ppm meter?
@Mañ'O'Green might be around and have some insight if youre lucky

I'm not using one at the moment no, I plan to get one in the near future but to be honest even if I had one right now I wouldn't understand how to use it properly. I will wash it out tomorrow and do a flowering mix but cut the grow bottle down. By half you think? Or is that too far? Also, you don't think I need calmag at all? I grow in tap water left out for a couple days. fairly soft with no chloramine added, comes out the tap about 6.8

You could give it a shot, You may just be giving her too much of everything... Im just a lowly dirt farmer so take my opinion with a grain of salt.

Mag deficiency. Don’t use cal-mag you need some Epsom Salt
