Yellowing leaves help please (newbie)
Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Day 20 Flower. Leaves curling
Leaves curled over 12 hour light cycle. Ph 6.0. Ppm 950. I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this. I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

The NL starts developing yellow leaves at the top of the plant. It started at the end of the leaves and it's developing. Any what deficiency (or is it overfeeding?) it might be ?

Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

Age or Deficiency
I have noticed one of the girls fan leaves have all started turning yellow and drooping. It looks like they are turning from tip to stem and some of the smaller leaves have also started to turn. Is this due to age or a deficiency of some kind?

Nitrogen deficiency??
Looking like I have a nitrogen deficiency. Thoughts and what do I do to correct other than what I've done already with a top dressing off earth worm castings and blood meal?

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?

Long battle with deficiencies.
For a week i have been fighting deficiencies , the ph seems fine. Part of the problem was fixed by calmag but how it seems to be something else, maybe someone can help me identify.mid to top leaves affected. Also overall heat could be a problem (as temps outside rise)
