Potential causes and fixes for magnesium deficiency
My runoff EC and PH are normal and I am adding calmag to every feeding so not sure why I might have magnesium deficiencies. Aside from giving them just a calmag feeding and foliars, any tips on what I can do and why this is even happening?

I want to be sure. Yellowing leaves and red branches, that's a sulfur deficiency. And that's generally due to the pH of the water. But if that's the case? Why does it always show up at the end of the plant's life and not before? My water is taken from a rainwater tank.

I have 3 grow rooms. I moved all the deficiency plants to 1 room. The whole half of the plant is turning really light yellow/ Are my lights too close to the plants ? Or is my feed to low?

PH measuring for Organic Growers
If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

Lime Green Growth Tipes
The growth tips on my plants are super lime green compared to the rest of the leaves. Is this a problem? I'm growing in FFOF and I've given very little CalMag and P-T-K so far.

Defficiency or light burn?
I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here? Ive added a tiny dose of calmag, can I supercrop this late into flower?

Zinc deficiency?
My plant's top leaves appear thin and pale. My ideas are iron deficiency or zinc deficiency. I'm using RO water. The plant was recently aggressively trimmed of course. Should i flush with non-RO water to increase the zinc?

Can anyone help identify this tox/deficiency?
Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.
