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.

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.

Dark tips it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

Gray leaves on buds with a massive concentration of trichomes. What is it?No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?
