Still trying to diagnose

Hey there. What exactly do you think is wrong with these two plants? Both showing same thing. Been giving them Ph’ed with more consistency, but has been raining a good bit. New growth still has these slight spots. Help please. In soil 30 gallon pots, soil Ph is between 6.5 and 7. One is a 50/50 hybrid. The more affected smaller one is an 100% Afghani indica

You got a ton of bark or mulch in there? It will raise the acidity quick if thats what it is.

It looks like a calcium deficiency. Most soils have plenty though. If something is interfering with your ph it will cause deficiency.

Yes that is what I have thought. If Ph isn’t a problem is calmag a solution?
[/QUOTEet rid of that mulch. Flush with water.

If you have lockout from the ph adding a nutrients/minerals won't help. Try getting rid of the mulch first. I would get ph with plain water, flush and get a ph on the runoff.
