One new top leaf is wrinkled too, so I would go with bad watering regime and overwatering . Pots has to be light before watering them again. All the Best !

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Taches noires sur les feuilles
Demande de confirmation de diagnostique: J'ai remarqué des taches noires aux extrémités des feuilles. Je pense qu'il s'agit d'une carence en phosphore? J'ai un peu tardé à nourrir ma plante. Dans mon dernier arrosage: Ph 6.5 EC : 1.8 Terra bloom, green sensation, pure zym. Merci

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.

What the actual heck is going on with these leaves
Leaves from all around the plant are showing these symptoms. Much more detailed info in grow diary but current runoff ec is 1.7 and problem is spreading quite badly.

Black spots on leaves
Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water. For about 2 weeks prior to this, I also added very small amount of kelp powder. Soil seems fine.

I’ve never seen this before?!
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?

The problem in plants when I supplying CO2
Hello! After adding CO2, I noticed problems on the leaves of my plants. Grow in coco+perlite, water with 1100ppm solution, 1000ppm co2 in air. Drain from the right 1400ppm and 1800 from the right. Is it related to co2 and irrigation system?

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.
