I have 2 Auto Ultimate‘s by Dutch Passion. One looke normal but the other one looks different, she has alot of thinner leaves and they droop. What am i doing wrong?
Each seed will have its own pheno type with a mix of traits from the mother and father plants so some variation is normal. As for the drooping one plant might drink water(or not) faster than the other so just keep a closer eye on it to figure out the best watering schedule.
Next time just start question from diary, that way you will help person helping you ;)
Can only agree with @Roberts amount of water and pH were two things, now he has calcium issue too ...
