Hey guys, so I am 35 days into this grow and have started to notice some issues. I’m not sure if it’s nutrient burn or light burn. I’m using a kingled 1500w on the veg setting and did have it about 32 inches from the canopy and I have raised it to about the top of the tent 2 days ago. Attached are my 4 plants. Anyone have any thoughts?

Using cal-mag and the general hydroponics trio micro grow and bloom. Feeding 3 ml cal mag, 3ml micro, 1.5 ml grow, 3ml bloom. This is my 2nd grow so I’m still learning.

Looks like light burn, or magnesium but not sure unless we can get some natural lighting pictures. (Please)

I would recommend feeding each time you water. Looks like it could be the beginning of a calcium deficiency. Common in coco. I would increase the cal mag feeding when you can.
If anyone else has some suggestions that commented, suggest another issue or add to it. Just want to make sure Blackhawk is covered.

I have been cutting everything in half because I was worried about nutrient burn.
I use coco and it is notorious for stealing cal. I never dont feed it even when just watering.

I dont know about coco. I use ffof. But I would have to agree with @Covertgrower just by what I’ve read about coco on here.

Also, its almost impossible to overfeed with coco. I feed every watering usually.

More or less, high she doesn’t need to eat, low she does. That’s the basics. From there you’ll wanna learn what numbers you want, because obviously you dont want them too high. And you gotta learn how to keep them wear needed and all that. I still have to get a tds meter and do all that myself. I just ph right now.
I wish that I could be more help. Never used coco. Actually contemplating getting away from any type of medium other than water for my indoor grows
