Deficiencies deficiencies.

They could be a variety of things. I saw some calmag def with the yellowing. Some possible potassium def/lockout. Could have been my ph. I was feeding water with a ph of 6.3-6.4, now got a ph meter and feeding 6.5-6.8.

What do you think the problem is?
I haven't put it completely on ph, because it has seemed to get worse since i fixed the ph issue.

I would say it looks like phosphorus toxicity. Causes trace element deficiency. Also the last pic looks as if it has spider mite damage.

how often and how much do you fertilize? what brand name and type is it (veg, bloom, or what)? what do instructions say on container, if any?
you've got kind of dark green leaves with dying leaf tips which usually means over fert.

Believe it was locked out. In veg I was using floranova grow and im thinking the ph didnt need much adjusting. Ever since I switched to flower and started using house and garden my Ph has been off. But the Ph issue is fixed so it shouldn't see much regression. I doubt all the effected leaves will heal, but all should be okay. I may pickup some calmag as well

Exactly. Would you recommend giving them a low dose of calmag? I can either wait for them to recover assuming it was locked out, but if it was locked out and now is not I dont want to overkill them with calmag.
