45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?

Nitrogen Toxicity?
Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

Can you confirm this is a potassium deficiency? This happened after a flush of an amended soil (SoHum), please take into account before you answer. I do have some Down to Earth Organic White Azomite Powder OTW, just not sure how much to add yet.

Cal-Mag deficiency?
My LSD-25 is showing a nutrient deficiency. The nutrient solution is at 900-950 ppm and ph is always between 6.0-6.3. I am already adding cal mag agent from canna as per vendors instructions to my reverse osmosis water and have added a bit more yesterday.

What is causing PK deficiency signs on mid leaves? Too little Calcium causing lockout??
Hey everyone, in mid and late flowering with my autos, all experiencing similar problems and I’m inclined to believe it could be due to a lack of Calcium? Could a Ca deficient plant cause these symptoms which resemble a PK deficiency?? I’m 100% adding enough bloom

Ppm in runoff higher than feeding
The run off ppm is around 500 and when I watered it it was around 200 ppm. Ph levels are fine. Does this mean it’s not getting the nutrients it needs? How can I solve this?

Autos reacting to All-Mix: Slight nitrogen overload?
Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

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.

From day 50 some leaves of the plant started to turn yellow. I had stopped nutrients due to an overfert problem. So, on day 50 I started with the nutrients again, but in lower doses. 2 week left to harvest. What should I do with this nitrogen deficiency? Should I worry?

Unknown rust on 7th flowering week
This started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?
