Thanks! I'm on my third run now with NFTG. The first run was one hell of a learning experience. Second run was a lot better but I still struggled with the Ph challenges like a mo fo (I use RO water, which, for me, makes for an acidic headache late in flowering with NFTG). This current run seems to be my best so far (I still have time to screw it up though, lol). BK has been a learning event for me for sure that has induced a ton of research (via lots of time watching Scott on Utoob as well as via the Nectar Bible, etc.) and even via pinging Scott himself for feedback. I am still, after my 1st run experience, terrified to use BK as a foliar (I had massive chicken claws of my own ignorant doing in my first NFTG run) and it definitely seems like something you want to "ease" into versus just dropping the hammer. One of the professional growers that Scott refers to is "Pig Farmer" (Heroes of the Farm (
https://heroesofthefarm.com/) fame) and he refers to BK as the "throttle" - use it , in concert with TONs of Herc, and it should ramp growth up like crazy. What I found in my 2nd NFTG grow was that I added it too quickly and, along with the aforementioned acidic issues, it ushered in a Ca (and maybe Mg) deficiency really quickly around week 5. The crop limped across the line and was still good (Greenpoint) but I probably attenuated the true potential due to my aggressive behaviors.
This run, I've slowly eased into BK - starting with ~2ml/gal and working up from there to current levels of ~5-6ml (hoping to get to around 10ml by week 7 or so and then ramping back off for flush. Obviously you have to honor the 6:1 herc/bk ratio (if not even more) and ensure you have the right ph and no deficiencies. Else, BK is going to show those deficiencies SUPER FAST. Sort of like revving your car up and running into the wall, I guess. But, it seems to be pretty "enabling" if you have all things right. I'm still learning for sure. Cerces has been an interesting P augment; seems to be a faster available form vs. bovine bone meal - perhaps creating a spectrum that induces 4-5:1 of Herc and 1-2:1 of Cerces-to-BK could work out. It feels like a science lab at all times depending on your strains and conditions. But, that's also what's cool about NFTG ...that level of control versus just using a larger "macro" all in one thing. Sure, it's harder but perhaps the result can be worth the effort? Or it's lunacy...but still fun.
So far, the best I've ran was with Greenpoint Seeds. Their GG4xGG4 S1 is super tasty - gassy pine chocolate; was a super fun and strong cultivar; despite my best attempts to kill her...she still put out some yummy. Dawg Biscuits was good too - I'm hoping the cure improves the finish though - the taste I can't really put a finger on yet but she's super tasty and stinky. I'm really excited about the Slurricane #7 that is in flowering now (with the Grandpa Stash). I have a few other Greenpoint strains I'm hoping to pop down the line in my glacially-paced pheno hunt
- Greezy and Sticky Icky. Only sort of drawback for Greenpoint is their photoperiods are 70-80+ days versus a lot of these earlier ones like the HSCs of the world. I'm hoping to try some more HSC strains and also Twenty20Mendo - A buddy did their "Glue Sniffer" one back over the summer and it was really impressive!
