almost looks like a pest issue... possibly russet mites.. is this outdoors? Indoors? Do you have any IPM programs in place yet?

First time grower. Looking for suggestions.
Should I be worried about the slight yellow on the edges of the leafs? They don't looks very healthy. How often and how much should I water during this stage?

Yellowing Leaves with Purple Spots – Need Help
About 2 weeks ago I posted about my plant's leaves turning yellow, possibly due to a grow light I'd just moved closer. I repositioned it to ~30cm, but things have worsened over the weeks: many leaves are discoloring, especially near the top, and some show purple spots. Any ideas?

Is this overfeeding or another more complex problem
This is my first Automatic plant culture. I've made some novice mistakes, such as topping the plants. They start flowering about 2 weeks ago, but the leaves are turning yellow with some brown spots. I feed with an old Nutrient I had here. Can that be the problem?

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?
