yellowing leaves problem

[herrer80]

Hi everyone, I have a problem with yellowing of the leaves since I put the clones in the jars with coco, I use for the first time a reflux system of the platinium hidro 40, pot 3,5 L. I prepared the solution with Canna AB plus rizotonic, I have Ec water of tap 0.5 with nutrients arriving at EC 1.0 and PH 5.9. I irrigate for 15 minutes twice a day. What can be the problem of the leaves that are fading?

Any calmag in the mix ?
Also what kind of coco (brick.etc) did you use.

I used cocco Atami substrates, no I have never used calmag, my tap water is already with a lot of calmag in fact it cuts it with osmotic water to have a starting EC of 0.4

classic salt accumulation for me ..
not enough runoff on the first watering after transplanting dryout
big runoff is important at the beginning.. if you look the ec of the drain i bet it will be high .. some elements block the assimilation of the others

i already had these symptoms
