hi, i have looked at the thread in newcomers and replied,
what soil are you in? how old are your plants and what lights are you using?
from what i can see looks like a mg deficiency to me, try some calmag, i am going through similar as bio-bizz does lack it,
also are you using the full bio range? i use bio-grow, bio-bloom and topmax,
here is my nute regimen:
veg: i feed my girls 500ml, i mix nutes up at a rate of 1ml grow per litre water.
flower: my girls get 750ml per day, i mix my nutes at a rate of 1ml grow per litre, 3ml bio-bloom per litre, and top max for the first 4 weeks fower at 1ml per litre increasing after to 4 ml per litre.
like i say ive used it for sometime and ive done well on it, i average 4oz a plant.
