Changed the pot size from 300mL plastic cup to 3 gallons smart pot
The grow media are Universoil, a home-made brand, mostly contain a peat moss and perlite, also the Mychorriza
Increase watering to 500mL per 2 days
Also add more of the Wicca Grow nutrients to 2mL/L and changing the grow light's height to 22 inches and dim to 300w (75%)
@Cheesebearger, the drooping leaves, discoloration and bushy way its growing is a warning. You have to leave it and hope it gets better. Let the soil go dry on top. I hope it pulls through for you.
@NexusDevil, Thank for the recommendation, I planned to do the Scrog later, that's why I'm trying bend down the bigger plants on the left side to make its height the same as the others in the right side.
I brought the seeds from the Linda's, It's the same strains but I guessed the genetic didn't quite stable at all.
