Hi, long time lurker, first time poster. I've been growing with NFTG fo over a year now, never had a single problem beyond first grow, never slurried(like to feel out my responses instead of a device dictating although I'm tempted to slurry from two non-bk feeds). Well last 2 feeds in wk2/4(one strain is a 7wk and 4 is approximate stage of growth right now) of flower I forgot my bk, next up is herc water. Should I be concerned with bk getting in the in rootzone after 2 Spartan feeds? There's no negative reactions, they got foliar first two weeks and bk in rootzone 4 waterings ago(before tea). Has anyone here added bk into herc water before? Should I just not care too much and just resume as normal? My conditions are a single #7 smart and (3) #5 smart pots, under BlackDogLED 400, 80F day temps and 65F at night with 35-40% humidity. Also since I'm posting, is 5.0 the latest bible version? If not I'd love a more recent version from someone please. When I feed I also Hades to 6.0 and oly to 6.5 after adding everything(6.4 in veg), except bk is dead last every time to save its reactiveness. Oh yeah and I use a 50/50 Coco/perlite mixed 1:1 with ocean forest with some amendments and mykos.
