What the hell is this?!?
I'm growing four different strains right now and only the Thai X Skunk is effected.
These plants will be my first attempt at cloning so I would like them as healthy as possible.
- Thai X Skunk plants around three weeks old
- DWC, ppm 300 ph 5.6
- only the very lower leaves are effected
What's wrong with the leaves and what should I do about it?
