This is a Casey Jones strain in an aeroponic sprayer system. PH 5.8 and 700 PPM on Botanicare nutes...plants are at 25th day of veg from clones. I was using filtered water(not RO) and just changed to RO to make sure that there weren't any other causes for isses. I'm not sure what this could be other than a Magnesium deficiency but growth is not as fast as I would have expected with an aeroponic system. I'm using RO with MagiCal supplements. I have 3 strains growing...all other strains are doing great except this one particular strand. Lower leaves are yellowing between the veins. Only a few leaves are on the severe side and a handful are showing symptoms. I've read interveinal chlorosis due to Magnesium def or chlorine, but I'm using RO now...not sure if that's what I have? Can someone experts chime in to confirm? Any solutions? I did suspect Mg def, so i did some foilar feeding of epson salt and RO distilled water...didn't really see any improvements and one plant started showing some PM so i stopped the foilar feedings....I've done a ton of research and haven't found a solution yet.
Need some expert eyes...is this Mg def?
