Spots on yellowing leaves
Brown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red. It starts low and eventually ends affecting buds too so I chop.

Nute burn or pH Flux
Ive noticed the tips are the faintest of yellow. Maybe ive mistaken Nute Burn for pH Fluctuations? Diagnosing: pHing both tank and run off showed different ranges. My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.

I have been dealing with a nutrient deficiency so added nutrients.It looked ok but then got a bit worse and I took some runoff readings which were 5.4 and then 5.0 the next week after adding lime to raise soil PH. How can I best raise the soil Ph being that I added lime already.

So plant #1 is still having some Calcium deficiency issues. I’m using RO water and giving the recommended dose of CaliMagic which is 1tsp(5ml)/gal. I’m in DWC and using LED full spectrum lighting. Why can’t I stop these spots? Should I give more than recommended dose of CaliMagic

Calcium Deficiency from P Tox?
Does this look like Calcium deficiency? This is from the mother actually, she is flowering for seeds. I’m pretty sure last feed was too heavy on the phosphate and not enough calcium. I just want y’all’s opinion in case I am missing something. It’s the brown spots I’m referring to

Help needed - harvest time?
Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.

Yellowing leave tips and clawing down, do I need to start giving more nutrients?
Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.
