you have a point cause my base nutes contains cal-mag . there is a big chance that is a lockout from excess Ca.
i will do this on sunday when i change reservoir.
hey guys thx for the answers.
I've changed the reservoir on sunday. sunday EC was 3000 μs/cm.
Today ( Tuesday) . EC = 2600 μs/cm.
Spots seem to not spreading those 2 days.
I ll change the reservoir next sunday , and i will lower the EC to 2500μs/cm
i have strong light with high co2 plus they are clones and heavy feeders. The 3000 ec is the highest i go with this clone , i know it sounds high but it is just in the beginning of the week . During the week i add just RO water so my ec is coming down everyday. It could possible be nute burn .
