Put your light up asap! You are cremating your plant bro. Light to close to the plant causes this

I can’t put the light any higher. And no the leaf doesn’t come out.. I was leaning to more of a light/heat stressed but wasn’t sure. It’s a es300 light should I cut back on the power since I can not raise it!?

Schützt sie sich?
Diese herabhängenden Blätter... was verursacht dieses Symptom? Hab noch kein Tagebuch über die (online) aber die Pflanze hat einen Schaden an der Pfahlwurzel seit sie ein Keimling ist. Ich hatte aber auch die RH nicht im Griff. Die war jetzt die letzen 2 Tage bei 45%. Zuvor ok.

Stained looking leaf discoloration..?
Anyone have an idea what is going on with these leaves? It looks like a stain but up close with super zoom, you can see almost little white dots. Can mites start on top of leaves? There’s nothing underneath the leaves Thanks

Defoliation - now or later ?
Hi guys today is day 12 of flowering. Normally I would defoliate around week 3 but she is very bushy. Is it safe to defoliate now or I should give her another week before removing any leaves ?

Leaf issues
Thoughts on the cause of this? Planted in ground. Rainwater only. Compost has been the main nutrients.A small amount of 0-30-50 booster powder has been used. Other plants are not as bad and the middle plant has no issues. All approx 2 weeks into flower.

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?
I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?

The Double Stuffed Sorbet I'm busy growing is starting to show some signs of nutrient deficiency. I believe it is either a nitrogen deficiency or a magnesium deficiency or combination of both. The leaves have dark green centres and light green edges. Any suggestions?
