I have 2 white widow and 2 super critical in promix the super are starting to show deficiencies I believe! I have been feeding them tiger bloom at half strength at least I am hoping these are signs of deficit the supers are exploding at the moment my pH is 6.4 and the widows look fine should I give the supers a good 1200 ppm feeding and some calmag or is this another issue?
No but I'd give them a small dose of calmag at this point if it ain't broke then don't fix it...unless you know of MgS04 def ps I gotta say if you can't paint them white translucent buckets a darker cover at least cover with some kitchen foil as roots don't like light
