I've read that it's a boron deficiency, but I'd rather be sure.

First photo mechanical damage to stick from wind and brushing. Second - clawing leaves, nitrogen toxicity. Slow down with food ! Less is more in weed growing. Golden rule !

Do these random spots mean nutrient burn/deficiency, or is this normal?
I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

Browning between leaf veins!
After my low humidity problem two days ago, she seems unhappy and the growth has basically stopped. I realize it should be slowing down at this third week but these brown, dry-looking areas are showing up between some of the leaves, the ones in the center being the worst. Thanks!

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.
Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

Did I over-egg the nutes?
The leaves turned like this after a feed and a Mosquito Bits treatment, guessing I over-egged it with the nutes? Plants getting close to me cropping them, might leave them to dry out from their last water then chop.

Spots on leaves, because of transplant, new light or overwatering in week 4?
The leaves have some brown spots on it, is it because the overwatering last time (like I think) or do you guys suspect something else..?

many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)
