can be iron but mostly they take it from lower leafs, ph, much light, mutation asociated with blue strains, and last picture leafs looks like damaged slightly with spidermites.
hey burmese, im in hydro, 3 weeks in to flower.
water temp is 63f
ppm is 1127 with ec of 2.1 and i maintain ph at 5.8, i dont get much fluctuation.
im using gh flora series, i also have hygroguard in there too.
im using, led bestiva 1200w set about a ft and half above plants, room temp is about 75f to 80 sometimes
theres no spidermites or any other kind of infestation and the root growth is extremely healthy, its just that the leaves are yellowing on new growth, old growth is fine, more toward the centre of the leaf outwards but its actually the vein area thats lightening as opposed to interveinal chlorosis. its a shining silver haze plant but is happening to some others also, its not a rdwc its standard dw and all buckets have slightly different readings but all readings in safe area.
ill try get better pics for u.
