This just started today. You can see yellow on the leave in the first picture pretty clearly, and there seems to be just a tiny amount in on the edge of the leaf pointing to the east in the second picture (the stuff on the cotyledon is just a little bit of dirt).
I was already planning on transplanting these to 1 gallon containers tomorrow. So far they’ve had nothing but Happy Frog, and 6.0 ph water. Should I start giving them small amounts of nutrients, or will the Fox Farm Ocean Forest soil I’m planning on using be enough for now? Anyone have any idea what’s going on?
