As you can see the big plant leaves are developing yellow spots. The new leaves look ok, but some have very small yellow tips.
I'm using fox farm ocean soil. I tried to clone last photo. Except the one on the left is a real servivor. It was nearly dead then moved from hydro to soil and she's growing. I feel the ocean soil has nuts in it. I tried some grow big at a very diluted solution 1/16 to a gal and looks like some burn.
