I read a lot . Its auto and I know it will autoflower without changing the light cycle. But i ask how long will it veg its about 20 days from poped up the soil .
Day 18
I think the problem is gone . Brown spots stopped appearing. I think new leaves are in good health.
Sprayed them with magnesium sulphate 2 times and water them with biogrow 0.75ml and 0.50ml biobloom per liter water.
I accept all advices and critics.
