The_Dudestarted grow question 5 years ago
Been feeding 10-10-2 bat guano (super grow) and now some 1-9-1 (super bloom) for 3 weeks, still getting brown dead spots on older fan leaves. Maybe still a phosphorous deficiency and plant taking awhile to intake the nutrients?

Rust spots on older leaves are sign of potassium (K) deficiency, on the other hand phosphorous (K) deficiency shows as black, dark metallic spots on lower leaves
motaman311answered grow question 5 years ago
The old leaves/brown dead spots won't go away on the leaves that have already been damaged. The PH drop and feeding too many nutrients will cause lockouts to other elements. I would continue as you are and if anything gets worse, or progresses then look at your feed schedule, soil, + stage of plant. Good luck and happy growing 💪!

Brown spots on bud site leaves?!halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Why one of the plants looks like is being flushed when I still have more than one week until the end of the grow, and I didn't start the flush?I'm growing the same strain from the seed pack, and I'm more than a week away of finishing the grow and one of the plants looks like is being flushed.
Both plants have received the exact same treatment, but one looks like is being flushed.
What can be causing this problem?
