I’ve never seen this before?!
BadGrowerstarted grow question 4y ago
Weird spots on leaf’s I’ve never seen before. Growing in coco with dry amendments and worm castings. Ph 6.7/6.5. Just gave some compost tea earlier today. And earlier this week some GH calmag because some of them are showing deficiencies for that. But what are these weird spots?

Your ph is set wrong for coco. 5.5 to 6.0 for veg 6.0 to 6.5 for flower. Your getting lockout do to improper ph. Set proper and look to new growth.
Robertsanswered grow question 4y ago
I grow in coco and your ph in and out should be 5.8 in vegging. 6 3 flowering. Coco is hydroponic growing in a bag. So it is suppose to stay 90 to 100 percent saturated. It is not a living soil, and will likely experience more issue on current path. Good luck 👍

Those dots are the signs of phosphorus lockout. PH for 🥥 coir should be closer to 5.8 to 6.0.

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.Is this a deficiency or some other kind of issue?
Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.
