Can anybody tell me what this is/means. New growth doesn't have these spots. Fed with fox farms grow big and calmag both at a quarter strength a few days ago but the new growth is healthy.
The burnt tips look like nute burn, the spots look like maybe some nute solution may have splashed on that leaf. What soil are you using? There may be no need for using bottled nutes yet.
You are opening yourself up to some criticism by this statement I've seen lynch mobs be sent out because growers use it. And it isn't geared towards cannabis. It's your grow and you use what you can afford or have access to. Miracle grow has time released plant food. That could be the culprit or the combination of the soil and the nutes are probably too much. The burn isn't too bad. The plant will most likely grow out of it as it matures. But, I would lay off the bottle for a few weeks.
Yea I know. I'm not really trying to go all out with this grow. I just sat down and read the bag and it has bat guano and other things in it. Ima let these 4 plants grow without bottled nutes and see what the outcome will be then next grow I'll use coco and bottle nutes and do a comparison. So far they all look like some pretty healthy and promising ladies.
For anybody who wants to see them. The biggest lst plant and the seedling are big bang auto (greenhouse seeds) and the tall skinny one is holy punch (also greenhouse).
