Kind of looks like it could be both light stress and calcium issue.

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?
Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

I don't think this is nute burn...
So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Leaves Curling inwards early veg
Hello I’ve noticed that the leaves are starting to curl inwards. It has been very hot over the last couple of days with temps in the high 20s and RH any where between 45-60. So not sure if this is heat stress or something else. Should this just rectify itself. Thanks

I'm having an issue with two of my plants, the leaves are curling upward right at the base of the leaf. My humidity is right at 57-60%, heat goes fro 76-81 during the day, watering once a day. Does anyone know what might be causing this? Im on day 10, by the way.

Guys been going great until I checked today. My top leaves turning grey white and crunchy on 2 plants. 3rd plant ok. What do you think too much Kool Bloom? To much heat from the light?? I don’t think it’s the latter I decided to flush for 2 days to clean it out??

First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?
