Think you have more than 10 days. Lots of plump left and even after it gets fat it's another 7-10 days. Several different things can cause interveinal chlorosis. The second one might be pests... less blotchy and more circular patterns of damage. if nute related it's looks to be happening toward the top which means one of the less mobile nutes. Not enough info to give a conclusive diagnosis. Got some leaf curl so something might be overfed a bit. check pH, look for pests, and i'd wait to see how it progresses more to have a more educated guess as to the cause. Doing the wrong thing just makes problems worse quickly.

Deficiency or Nute Lock?I was a told a week prior I was feeling too much. So I stopped. I left town for 4 days and came home to the current photos. One looks like nitrogen deficiency, the other looks like calcium deficiency except I've fed 1tsp of tiger bloom, .5tsp of Cal-Mag and big bloom last week.

Slight Yellowing on tips of new-growth? (VEG)Why am I getting slight yellowing on the ends of new-growth leaves? It's affecting every plant. The only clue I have is that it might(?) be related to very cold nights because of my re-vegged photoperiod showing purpling on the edges of its leaves. Any ideas?

Why do leaves turn yellow and die Does this look like underwatering, heat stress, or any kind of defficiency? Also might be rootbound, cause I used not a lot of soil which also makes water evaporate faster. I water 0,8L/2 days pH=6.3=runoff, If its hot some leaves start to droop in less than 48h after watering.

Underwatering Issue or something else?I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering? I’ve been pHing between 6.2-6.4

yellow/copper appearance in some leaves after first run off watering hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?
