Yellowing of the lower leaves during flowering is quite normal/common, but either add or up your P/K booster to help your plant, she will be hungry for phosphorous (P) and especially potassium (K) during flowering.

The damaged leaves won't recover, but it will prevent the other leaves from suffering the same fate.

Help calcium deficiency
I think I have a bad case of calcium deficiency? This started shortly after switched to 12/12. I added 1/4 tsp to a liter of water 2 days ago. I’m not seeing improvement. Am I right ? Will the leaves turn back green (how long)? Is it something else? Will it die?

What could happen? Low temperatures? Over-fertilization? Or lack of nutrients? Please help, it's the only leaf on the whole plant that looks like this.

Hey folks, I just noticed some kind faint yellow dots appearing on a couple of the oldest leaves on the Elixir. Any idea if its something to be concerned about? It's my first grow and I have no idea what it could be. Are they just old? Nutes? Disease? Temp? Humidity?

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?

Quickly yellowing after possible over watering
That escalated quickly, within 24 hours we have lots of yellowing in lower center leaves on 1 Tastebudz and 1 Ethos: Adding cal mag to next watering. Would cal mag be better or Epsom salt at this point? Would a bloom tea help?

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.
