Yellow/gold spots on top fan leaves in bloom phase
renbudsstarted grow question 2y ago
I noticed a couple of the top fan leaves have got some small yellow/gold spots developing. I've been using the same Bloom feed for this plant as my 3 Bears Smile which is 8 days further along. I'm wondering if that might be causing the problem and how I fix it.

This is burning from nitrogen toxicity/over feeding.

Pienso que su ec está un poco alta. Baje la ec a 1.8 y si algunos de sus fertilizantes que aporta a su dieta tiene nitrógeno eliminelo de su dieta.

First thing i see is nitrogen toxicity. Dark green, Shiney, leaves is toxicity. So from what I am seeing is you are not getting enough run off, and your substrate ph is probably drifting out of a safe range. Or just did not long ago.

Yellow lower leavesLower leaves are turning yellow. She just started her second week in flower.
My first thought is I'm not feeding enough. She is short, but still a lot of plant here. Here upper leaves are a nice shade of green. She prays all day long.
Is this a problem.Leaves. Color - Yellow

What are these yellow/brown dots and how can I prevent more from developing?Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.4y ago
