Leaf problem and purple stems

OwnWayGoodWaystarted grow question 6y ago

Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

I read online that it could be caused by to much P&K from the boosters causing a magnesium lockout. I'm having similar issues and that's what I have settled on for my diagnosis. Hope that helps. Happy growing.

And also light stress. Could be to close or too strong.

I don’t think it’s a nute issue. Could be your Humidity. It should be around 30-40 %. Also better air movement should help.

Tips of leaves turning (again..)Why are the tips of leaves curling up again? This is happening only in one plant. Other plants are looking very healthy, this too but the leaves are just playing around. pH and EC are right and it shouldn't be too hot.

Brown spots, PH in run-off is in the high end (6.5~)I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?
