some weeks ago i bought a reverse osmosis system. in the first time i was very happy and tried different setups. i tried mixing with tap water 50/50 and 30/70 but the result was that my moms in rockwool had bad deficits. so i bought calmag and tried nearly pure RO water with calmag. first with an EC of 0,5 later 0,8 (that destroyed my harvest) and now i use 0,2-0,3 EC. but the problem is always the same. my plants have deficits. it's strange that different stages of the plants have different levels of deficits. the cuttings in the propagator look really bad
the rooted plants look always good with slight deficits
(like the ones in the back)
the moms which are made of the leftover rooted plants look shitty again
the plants in the flowering room on cogr are ok with slight deficits and some troubles in the first week after moving into the flowering room. but that also happened before the ro system was installed.
what i always see:
-not all the plants have deficits. some look good
-young leaves lose colour between the leave veins
-old leaves look shitty and die
-plant grows slower
-deformation at the edge of the leaves, sometimes they roll a little bit
i use calmag, rhizotonic and canna nutes (EC in the end around 1,1-1,2). does anybody have an idea what i do wrong?
thanks in advance
