First, It appeared after feeding; second, you gave PK where there was no sign that it was needed. Those rust spots are a classic sign of Potassium (K) toxicity. Flush and give it plain water for at least a week, so it can recover, then restart biobloom only, do not use PK 13-14 unless you see signs of deficiencies.

Hi there, so when I had a similarly reddening of the leaves it happen twice for two reasons, the first attacked all leaves and was due to calmag overdose, the leaves eventually crisp and died off
The second was only some leaf tips, the the ones.most exposed to light was due to calmag deficiency. Yours looks more similar to the deficiency. Try a low calmag dose like 1/4 tsp per gallon and see if the problems doesn't get any worse.
Happy growing.

Red spots are calcium deficiency.. PH variations ? Too warm? Just give her some calmag on your next feeding, and she will reward you... Good luck with your grow !

Hi @Gmalin105! This looks like a cal/mag deficiency, this may have happened because of wrong pH in your feedings, or too much Potassium. Do you check your pH? I would stop pk13/14 now and give her a good flush for a few days, only plain pH'd water. Then if she's not showing signs of recovery (on new growth) after a week, add some cal/mag to the water and see how it goes. Hope this helps, keep us up-to-date and happy growing 👊

Plant health assessment (Leaf coloring and nutrition help)Sorry for bombarding you guys with questions, but it's getting serious now, right?
Anyway, my leaves are getting funky colors and I do wonder, what is causing this?
Is this normal? I have used the bloom nutes as in my diary once this week, rest was distilled watering.

Yellowing and Reddening of older fan leavesI’m experiencing a lot of yellowing that progresses into dark red blotches. I suspected a possible cal mag deficiency but after upping the dose multiple times I’m still having issues. Any recommendations on possible causes/treatments? Temp stays between 74-76, humidity around 60%

Red pattern at the bottom of the leafNoticed the appearance of this red pattern at the bottom of my leaf. Could this be attributed to plant stress? The new leaves are very green and healthy, so I am thinking this red pattern is associated with some stress the plant suffered in the early stages of development.

Disease or Deficiency? Or something else?Red spots appear from bottom up & now at very top, I think they had nute lockout before from underwatering & silica buildup, watered w/ calmag only last 2 waters, top leaves have burnt edges, some leaves came off. Runoff PH was 6.9. Leaf septoria, nute deficiency, something else?
