Possible manganese deficiency?
Jake13255started grow question 4 years ago
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.

Lower your ph to a 6.2 range. Plants have a good absorption rate for cal mag around a 6.2 range. Also make sure your having good run off to flush old nutrition out that is used as your replacing it. The plant still needs phosphorus and potassium at this stage as well. Not a lot. Good luck hope that helps. Happy growing 🌲🌲🌲👊

Could be manganese but I think calcium is more likely. Just make sure one or more of your nutrients contain micronutrients.

Is this a disease caused by a lack of calcium and magnesium?I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Ongoing brown and yellow patches forming in week 6 of flowerI've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

Why are there soon many brown spots all of a sudden in WK 7?I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?5 years ago

Leaf damage/discolourationThe Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four
