Big Buddha Blue Cheese grow

[Canublay]

Okay. So I am growing four blue cheese and a strawberry blue from World of seeds.
Recently I re potted and my favourite plant has really stunted.
It looks like my soil is harming my plants. I am using plagron bat mix, which I have heard wonderful things about. Three plants got repotted into plant magic and are looking very lush, but the two bat-mix plants have dieing leaves and one is stunted as shit.
Here are some pics.
Any solutions? Should I just wait?
Also when do you think the optimal time for floweing would be judging by these photos, they are currently four weeks old under a 400 watt HPS.

Cheers.

hey bud! ..sorry to see such sad ladies,... two things happened for sure: shock from the transplant, and that soil is waaaay too hot for auto's! I've seen this before with this soil,.. the NKP#'s are in the teens, and even if it's organics and slower released, it seems to be too much at once,... First pics show definite N-toxicity-- the clawing of the tips... drooping, sagging, is shock symptoms (root trauma),... the dilemma now is how to fix thing without shocking the plants further,... the more okay ones can be treated with B1, or Superthrive, for shock,.. the batpoop soil ones, tougher call,... moving them back out into the other soil might be just too much for them given their state,... flushing the soil with about 3x the pot volume will leach out some of the excess nute's, but flushing is a sort of trauma itself,... the lesser of evils, IMO though.... it's time consuming process, and water, let drain, water more, let drain,...air pots can foil this process, because of the free draining sides! :slaps: you should add B1 into the final flush, and many recommend a 1/8 dose of nutes mixed in as well, but I'm of two minds on that in this case,... water logged soil smothers the roots- poor gas exchange...so a trick to help pull water out faster: take a 1/4"+ stack of newspaper, and place several paper towels on top,... make sure the towels make contact with the drainage holes, to help with the capillary action draw,... let sit for several hours, checking for saturated paper and replacing if it soaked,...this may be a challenge with the air pots, so stuff lots of PT's up the base and see how that works...

Pics in HPS light make for difficult diagnosis, so shoot some in normal light if you can, of the affected leaves, though I'm pretty sure of what I'll see,...just to confirm!... this trauma comes at a bad time, right at early bloom,... assuming these are auto's, yes? It's worth a try to save them, but end results may be sucky,..hard to say, some plants recover well, others don't,...

Hi mate, sorry I forgot to mention these are not autos.
Only one of them is looking unhealthy, and I am thinking maybe I should remove her and just flower the others a week longer? The strawberry blue that was repotted into batmix is looking alright, but was only repotted a week ago, so she might also suffer. I didn't know mixing soils was a bad idea :| Some lower leaves of the plants are going dark and crisp I should mention. Do you think if I prune and wait and water plain water the problem will be okay within two weeks?

...well, I'd like to see how bad she is first, but still, your call,... roger that on them not being auto's, but diagnostically, that doesn't change things much, you just have actual time to fix things now! Forgot to ask before, if you have soil pH readings? And are they different strains? ... mixing soils isn't necessarily a bad thing, but doing a "soiless" and true soil blend can make for a poorly balanced soil,...needs tweaking! .....Prune nothing, and post some leaf pics too please!

Hi thanks for getting back to me. I have not yet flushed I have been a little apprehensive as the pots I have seem to take ages to dry. But I will, I am bummed. Growing aint easy! I also do not have easy access to the water additives you have suggested.

oh yeah I forgot. My PH readings seem to flunctuate from around 6 to 7.4. Although I just have a cheap electronic soil PH tester. Which I think is inaccurate. I placed it in the batmix before it had been watered and got readings higher than 7. I had heard of people using batmix and plant magic without adding anything and being fine. So I didn't think I would need to worry about PH too much.. I also added dolomite lime to my soil

Just a quick Update,. All the plants are looking far greener today. The one in the airpot is still yellow, stunted and shitty though.

...that one may not recover well at this point, but great to hear the others have turned the corner! New pics look good,...still see some recent tip yellowing, slight nute burn,...so be mild with your ferts,...
