Hello guys. I've got problem with my two plants. One of them, Cheese, has got a lot of yellow leaves. I don't know it's time for her, or she just feed, eating own leaves, idk. Next one is Green Crack, there is this type problem. Check this please.
Looks like they want more feed, but this could also be a cause of lockout confirm your nutrient are giving them enough food.
Autos like to feed lightly, when using liquid nutrients its best to use a EC/TDS Pen to confirm the correct strengths are being hit.
I'm also noticing some signs of calcium issues in the leaves as well. May want to look into a CalMg supplement for them.
good general reference pint for auto strength feeding guidelines.
