Deformed leaves with strange discolored stains

how much per litre are you giving the plant of which nuits? 

As per instructions 2ml per lt, 2 lt per week

At first i thougt it was nutrient birn, changed 3/4 of the soil. Washed and after started to give the treatment with advanced nutrients, i mix all toghwther as per instructions. Now is the 2nd week but i dont see any improovments...the first photos are from 2 weeks ago. The last one are done few moments ago

Yer transplanting them wouldnt of made them happy mate, when you mess with the roots the leaves will grow deformed n shit for a while. You should just give it time to recover, and itll grow normal growth again. 

maybe drop the nutrient dose to half recommended? Let's see what the coco growers think. They can recover much easily from underfeeding then overfeeding.

I'm at a loss because there are a lot of different factors involved. The 3 media mixed makes ph targets somewhat difficult. Coco wants 5.8-6.2 and soil likes closer to 6.5-6.8. The ph level of the feed is really important so that the plant can feed properly. The nutrients you are using are for soil and they automatically adjust the ph for soil, not coco. The ratio of soil to coco could determine how to run it but without any information available I'd say it would do better at coco ph levels, I could be wrong without data. If you are feeding at the rates listed on the bottle, that generally is high bordering on too much. I agree with Galandil, half rate the nutes and see if she improves. whats the ratio of each of the media?

I would say is 70% soil 20%perlit 10%coco

10%coco

I wouldnt count that and treat this as a soil grow

soil for sure  the coco and perlite is for drainage

Good morning to everyone and thanks so much for the tips. The started to show signs of improovment. Bytheway is 2 day in flowering cycle with 12 hr lights. The new leaves as you can see didnt show many stress sogns or discolored patterns. I was thinking that maybe the cause was the fan too strong? I had 2 fans, one little still active and is making the plant slightly dance, the other one (that i removed) was much more strong and the leaves where clearly moving too much. Now let'only hope that is a female (i'm about 70%sure) as these are not buyed seeds but found one

Updates: the lower and bigger leafs got yellow with some stains on them. Suggestions?

Looks like a potassium deficiency/lockout probably caused by Ph issue...what Ph are you now feeding at ?

Ok i don't know what the fudge is happening right now...poissible overwatered? Any chance to recover it at this point?

Definelty something going on, but whatever it is is fixable mate so dont panic. You have some signs of bugs on those lower leaves, ca you get some closer pics? She is looking better than last time we saw her so there has been improvment
