I'm using RO water and the ec level is very low since i have very young clones...

My clones get full strength as soon as they go in. If your clones need more than you think, they could be pulling the nutrients out of solution faster than they are pulling water, causing the pH to rise.

full strength? no root system yet... so i'm using 1/4 of full strength, strange thing is that it never happend to me before, it is not the first DWC run...
thanks for your reply bendo

try adding a bit of cal/Mag then see if the PH is stable... I have read RO has issues with PH if cal/mg is not added.. Wont hurt to try it..
