Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

A few of my leaves have got these marks on them, 2...3 at the most. Is it something I should be worried about? The nutrition I'm using is noted on my diary. Thanks 😁

They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Organic grow, yellow leaves, autoflower
First ever grow. I'm in my 5th week of autoflower, organic grow. Using the bomb paonia soil, raging kush light and boogie brew tea and filter to water. Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?

pH or root issue. Temp increase at same time.
Either pH or root issue ..? As plants recently had a growth spurt the temp in tent increased from 28 to 33, does this happen with plant growth? Nothing else changed.
