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?
Looking under or overwatered at first glace, no idea of your setup.
Check the stems connecting the leaves to the plant.
If both the leaves and stems are floppy is needs water.
if just the leaves are floppy it had to much water.
Good Luck
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 ...
