phosphorus and boron anomaly
Could someone please explain the precise mechanism underlying the phosphorus anomaly? As anticipated, availability decreases with increasing pH, yet it exhibits a sudden surge at pH 8.5. What is the exact (bio)chemical rationale behind this phenomenon? Boron has a similar pattern

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Spots on lower leaves. Edges.
I have spots on lower leaves. Already trimmed some off. Thinking it's cal as I'm growing in coco. But as I switched to 12 and 12 could use some advice. Seem to be mostly on edges and tips of leaves ( where lights hitting ).

Calcium deficiency, cal-mag now in hand, water now, or wait for normal scheduled water? Last water yesterday.
Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer. Should I wait for my next water (2 more days) or give a single dose of Cal-mag now, to get some calcium to the plant?

Deficiency of nitrogen
W.Gelato seems its taking too much nitrogen. Ive already made top dressing with worm castings and compost teas but still hungry. My question is: should i add some small dose of NPK mineral based (i have PLAGRON coco A+b) or it would do more bad than good since im doing organic

If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?
If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine? Humboldts Secret nutes, Glueberry Og Auto, rh48 temp74-76, advice appreciated.

Light burn, light burn due to humidifier water lights?
What do you think caused this brown color on that leaf? I have 5 leaves like that, all the others are ok. I believe it's due to pulverizing water and droplets acting as magnifiers for the light, causing small burns. Also, since they are burnt, should I just cut them out?
