... OK, the odd leaf is a fairly common growth aberration, nothing to sweat at all there,.... the color break patching is also fairly common, usually isn't an issue either, all in all looks minimal,... the last pic isn't far enough along to make a call, if it's anything at all,... I'd start feeding more though, ramp up the dosage conc. because 1/4 is too weak by now,... TaNgs sched' is a good reference!
using bloom nutes only is something called the "lucas formula", and it's very conditional depending on exactly what nute line you're using, and the NPK#'s in each part of that line-up,... [HASHTAG]#1[/HASHTAG] problem is, most of those line are meant to be used together, and if you reduce or skip one part, you may be shorting the plant on other nutrients besides NPK,.. they split them because not all nutrient components play well together, a lot of potential cross reactions resulting in compounds formed that lock up vital elements, and totally screw with pH, etc.,... If you're new, don't monkey around with custom formulations, unless you want to roll the dice and very likely end up chasing problems most of the grow! K.I.S.S. is the way to go until you have some solid grows under your belt,....[emoji106]
What's the scoop on these lights? Are they actual grow lights? Piecing together the right spectrum balance is no simple task, and if you're using pacthwork lights not meant for grows, or a bunch of specialty lights hoping it covers the bases, you may be rolling more dice here,... to figure all that out you'll need the full details about what exactly each light is emitting for wavelengths, and if that's what's needed for the right stage it's in,.... Big picture, more and more research is showing that blue/red only isn't optimal, it's not about just what drives the photosynthetic machinery "best"... there are other pigments that use different wavelengths, and other colors/wavelengths, especially green, far red, IR etc., that serve other purposes and have different utilization by the plant.... If you watching the light industry closely, you see more and more "white light" type showing up-- COB's, quantum boards, and the like,...
