Yellow spots on bottom leaves.Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so itβs not a matter of being locked and Calmag is also used. Canβt figure out what the problem is here.Leaves. Curl down

Yellow leaves with brown patches between veins.Any ideas on what this could be? I checked the PH and it is right around 6.5. I did feed them twice last week as I was out of town over the weekend. When I got back the temp in the tent was Β°91. It's bad on one plant and starting on another. The rest look healthy.Leaves. Color - Yellow

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it π
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water π

Plant seems to be dying, should I flush? And if so, any tips?Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.Leaves. Curl down
