It's only one leaf? Probably just using the stored nuits for bud growth

Bio Grow burn vs Bio Grow boost
Hi, it seems like she keeps getting nute burns as soon as i give her Bio Grow, even at half dosage (1ml/L). She has only 10 more days of veg and i wanted to boost her, what if i stop giving Bio Grow altogether until flowering? Is the tradeoff worth it? No burn but less growing?

Cal/mag problem or heat issue?
A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

Likely potassium deficiency on one of my phenos? Can someone please confirm?
Looking at my plant pictures on 2nd of feb, #1 (plant on right) seems to have some sort of deficiency. Looks like potassium. For the record I dont use liquid nutes. Only dry organic amendments and I have not watered or top dressed in roughly 2 weeks. Thank you in advance!

intervenal discoloration, organic grow
Gave her enzimes last week, maybe they were too much or some nutrient lock out due to a somewhat excessive fertilization (too much vermicompost) Think I will go on with plain water to the end I think maybe the problem will sort out itself or wont degenerate too much. Any advice?

Deficiency?
What is causing this deficiency? UsingProMix HP, top dressed with worm castings, and foliar spray with Epsom salts. I think it is Fe/Mn/Zn deficiency that looks like magnesium deficiency, and it seems to happen to all the plants at about this age. Mega Crop and kelp to fix?

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.
I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?

New grower with questions about burnt tips, browning/scrunching leaves and some pale/yellow spots!
I noticed Quick One had issues with burnt tips and discoloration by the end of week 1 and 2, what could've been the issue? Apple Fritter is looking sick, brown spots, what is that? Easy Bud and Quick on have slight yellow/paled spots on their leaves, only 1-2, is that normal?
