@CannaCountry Thanks for the feedback.One thing is for sure, your problem is consistent. What pH are you managing and at what temp are you managing your reservoir? They look short on Mg, but they also don't look happy...I'd start with my pH and go from there. Good luck.
@cananoob85 Thanks for the feedback.I have the exact same problem, just posted here: https://www.rollitup.org/t/tips-turning-yellow.1012333/
In my case, the leaves are not drooping down. Do you know how all this began? Did it start with only the tips turning yellow?
@peterstoke thanks for the feedback.they are dropping bad they look over watered
@cananoob85 Thanks for the feedback.
just checked your post. How much its your EC?
I didnt know which one come first. they weren't 100% healthy when I transplants from DWC.
@peterstoke
I haven’t done soil for years. I can not give you advice on your issue. But proper PH and EC measuring tools would help a lot.no idea about my EC, I do not have a tool to measure that - yet. I've only got PH drops (ordered a proper PH meter yesterday) and it's supposed to be about 6.5.
I've only tested runoff water once and it was over 7.
It appears OP is running an RDWC hydro system...they are dropping bad they look over watered
