Brown black spot crispy edges
lovely_neighboursstarted grow question 3y ago
I need help! Northern Light has Reddish brown spots turning dark-gray and crispy dark edges on the top leaves! It looks like a different issue from week 6 where gray spots appeared on the bottom leaves? Any ideas? Thanks

Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

Is this nutrient burn?I'm pretty sure this is nutrient burn. Using hot soil with a bit of extra worm castings on the top layer. The pH was also too high (approximately 8) but has since been corrected (now 6). Next layer on top came in nice and healthy. Can someone confirm there's nothing to do here?

I think underwatering combined with the light being close has caused my issue. However older leaves have also dried up and died (but staying green).
The way the leaf looks with yellowing though, and because a couple of leaf stems are turning reddish, maybe it's K deficiency?Week 6

Leaf damage and flower analysisAsking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Leaves developed strange textures, How to fix it?So it's Day 45th Today (7th Week) and Pearl developed some brown/orange/yellowish textures on it's leaves which you can see in the pictures. What's the cause and how do I fix it? 😭
Also lower 2 nodes lost coloration and are now yellowish, is it because of not enough sunlight?

Burnt or K deficit? Or offended?Please could you tell me what you think about the (burnt?) edges?
My guess is that I should water more often to lower the concentration of nutes in the soil?
Nutes are RQS pellets in the soil, watered with plain water every 10-12 days..

Leaves turning yellow with brown patchesI noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.
