I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Why does my bottom leaf have brownish white tip and is cripsy?
Was checking leaf temps all over and at the very bottom first 3 point fan leaf that she ever grew I noticed the center leaf crispy at the tip with some light green spots around it. The only other leaves that look like this are the single first true leaves. Thoughts?

Just switched to 12/12. Fed full strength based on fox farms diagram (not the micros as I don’t have them) only looking light colored, should I continue with a round of just ph water still? Or another light nute feeding based on its color. In OFFF/ cocoa 50/50

Leaf discolouration -- what's the reason?
Growing 2 plants under exactly same conditions: one is completely healthy; the other one got some leaf issues. The discolouration starts in her older leaves and then spreads onto the younger ones. Been giving them stimulators with the following: Ca, Mg, Fe, Mn, Zn, Cu, B, Mo

Nutrient or water temps? Water temps between 15⁰C and 20⁰C but usually closer to 15⁰C.
Not sure if it's a nutrient deficiency/excess or water temps. Please refer to pics. 2/3 plants are showing light green and yellow tips. New growth seems light in colour as well. pH - 5.9 to 6.1 Daytime temp - 75⁰ to 79⁰ Night temp - 67⁰ to 70⁰ Coco with Gaia Green 444 and 284

Leave issue
What is this? Nutrient burn, deficiency, fungus? I tried to look up the answer but it might be different things on different plants. Please help me diagnosis this. The white powder is DE and the small holes are from flea Beatles. But I’m more concerned about the browning.

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?
