the pictures are of two leaves at the very top of a bud on two plants out of 6 in a common bubbler tub they are master kush the others are chronic and kali. My PH is between 5.60 - 5.85 canna aqua nutes at 925 PPM 2.1 EC air temps 73 in room 78 at canopy level lights on and 73 lights off they are at day 29 of 12/12 and about day 17 of flowers showing. Resovoir temp 70 crisp white root mass. There is no yellowing at any other leaves below the bud or on the surronding upper fan leaves only on the little secondary resin leaves. I f this is nitrogen defeciency why only on these leaves and no lower leaves. Could this be light bleaching? my canopy is even distance from the lights and the other 4 plants show no sign of this but using a light meter these two are in the highest output area under this reflectors pattern. I think this some kind of defeciency but i have looked at numerous pictures and can not find a close match. I have heard master kush can need a lot of nutes. I use RO water could it be a CAL/MAG defeciency. If it is nitrogen defeciency how can i increase on these two plants without affecting others maybe a foliar feed of some sort on these two . Help im lost maybe somebody has been through or seen this and knows what it is an what to do
