Those are signs of Calcium and Magnesium deficiency, but are we sure it's a deficiency? How are the roots? Do the plants take up as much water as last week?
These were in coco right? How's the drainage like? Does it smell? Measuring pH in coco is a b!tch, but maybe it is pH...Maybe @Mañ'O'Green can chime in?
Anyway, a dose of Bactrex for these girls will surely aid in getting that soil in tip top condition again

I went back to my old posts when I grew this girl last same with biotabs and I got the same issues on the last 2 I grew and I gave her half a biotab in her soil and a small dose of silicium flash and that put her right then but she was much bigger than this girl and its in my threadmarks

Oh, man...How many grows do you have going on then...Yeah in soil nitrification is a serious risk, but then again you can take a pH reading from soil, right?
Then, to see if the solution to your problem is nutrients, you could give a foliar feeding with some cal/mag...

I only have 4 plants in my 4x4 photos and 2 autos in my 76x76x180 but all in biotabs so sorry for the confusion lol also I took a ph reading from the base of her and it was in range with an ec of 1.4 too also I have remo calmag no organic do you think that's could mess anything up as I can deffo foliar feed her

A light foliar feed just before lights on can do the trick mate. Might help her get back on her feet faster, together with the aid of the half BioTab and Silicium Flash?

 

[Mañ'O'Green]

This looks like a micro nutrient shortage to me. If you have some Earth Juice Micro Blast I would give it a dose. I think you are a little late to use foliar applications but..........

Week 6 trichomes and cream I started early with some light brown speckling and now it seems to be spreading so I'm unsure how to proceed as I have very low ec starting water at 0.2 0.3 so there not a lot in my tapwater I did give her a small amount of pk 5.8 the other day maybe too early but I'd already spotted the problem beginning but maybe it didn't help :smoking: anyhow I've just given her a little flush her ph was in check and her ec was 1.4 so she seems to be in good shape so I'm just going to let her plod on I recon

Kind of looks like a chlorine deficiency

I use EcoThrive - Neutralise so I shouldn't have any issues with that should I bro and thanks for the suggestion any tips always help and I've never seen those pics either

Good afternoon folks and today a pic of my droopy draws strawberry chemdawg anyhow I've let her completely dry out 3 times now and top fed her but she is still drooping some I'm thinking maybe it's just genetics so I've even messaged sssc and I'm waiting on a reply anyhow let me know what you think folks and @Bob's Auto's I'm not sure what I can try now I mean she's still growing

That almost looks like a pH toxicity, but knowing your growing with Biotabs, this shouldn't cause an issue normally. Could well be a combination of things and a fussy phenotype. Personally I would pluck all the yellowing leaves etc and gradually get her back on some food. It could well be nutrient lockout and issues because of the previous waterclogged soil etc. Difficult and time-consuming to get over.

Indeed, it looks like it. Extra feed of Ca/Mg could work, whether sprayed on the leaves or in the soil.

What is the temp and humidity like? Do you have any cold spots in the grow rooms? And what about the light, is the PPFD level in optimum range?

Could be the start of other problems.. What I have usually noticed with Biotabs is that it doesn't hurt to give it some extra (micro)nutrients during the grow. I personally prefer B.A.C in combination with Biotabs a lot. GL mate!

Well Antonio I think you hit the nail on the head regarding the pH I took her out yday as I'd tried everything besides flushing her and low and behold her pH was at 5.5 even though my tap water is 7.0 but I had started lowering it in the last week so hopefully this will get the big girl out of her funk so that's the big girl :smoking: so let's move on to the autoflowers now the leaves changed pretty fast on her so I will remove all the damaged stuff and I could at least give her a spray with some calmag today and regarding temps there optimal I think and my rh is around 50 so I'm thinking it's something in her soil and maybe I need to buy that product as it will come in really handy and could you possibly send me a link to it .regarding ppfd I've got an app but I'm unsure how to use it and at canopy what level should I be sat it as as the moment I'm around 35 cm from the tops and sanlight suggest 30 I beleave but I can always lower the plants down as my lights at the top of the yoyo hangers

Glad you figured it out buddy!!

I've done just the same in my last soil mix. I added a baggie with a special micronutrient blend for Orchids. All the hard to dissolve micros are presented in a EDTA bonded form.

bob shes been driving me a little mad as in coco I would have had her back on track in 2 days but I feel with this organic growing its like going back to the drawing board with me I'm learning as I go but bob id be a little bit fucked without your helping hand .also I went into the smaller auto tent and sprayed her pretty good with remo magnifical at a pretty high dose and I know it wont fix the damaged leaves but I'm hoping it at least halts the others getting affected so fingers crossed m8 i will also remove all the damages leaves at lights on
