speaking of the mix .. i fished for a proper start and came up hard. i was at the folks and couldn't remember my login so the forum wasn't as accessible. i paged through a couple of the threads i knew were relevant and sorta spun my wheels.
then figured i'd use where we were at as a base. i checked the greenleaf site and got a base estimate of the current ppm. we were running at about the 800-900 ppm mark, with an ask. so i didn't want to go too much hotter. our ppm level for the MC was already at the late flower mark, and if anything i'd probably want to pull back a touch, but i took 900 as a base guess high side.
i then used the suggested amount for the BE as a launch point, and decided to build a mix on ppm.
the online feed sched recommended a bit over 3g if running at our current level, and roughly 2g at what i considered our actual point of development. i went with the 2g, even though most would call it hot. they are likely right.
the 2g amount was supposed to be worth 150ppm in 8L of RO. i started with the BE because i wanted to ensure i had the headroom. actual was pretty well dead on after adding the BE to the RO.
my RO books in between 5 - 7 ppm so the BE is dead on.
next i carefully added in the MC. checking the greenleaf website suggested that we were running a bit over the 800 mark previous. it would look safe just to add what we ran before to hit 900, and be done. but it doesn't work that way.
i crept up to it by first adding in 5g of MC. then let mix dissolve nice and took a boo.
5g bumped my ppm a pile - 460ppm-ish. i guessed it would be a touch less, but it gave me a decent idea of how steep the stuff runs. using BE with MC does not act as a straight additive , ie: 1+1=2 , and MC can be all over the map on a weight basis, which is mainly how it is used.
oh yeah i would have used ec as my measuring basis, but i had all my gear set to the 500ppm scale (tds). i'm totally north american lol
i added in another 3g and wound up a bit bigger, but in the range of where i wanted.
we've been running a bit of calmag since mid veg on this run. 900 is hot but still gives me theoretical head room. i've run 1100 - 1200 in hempy previous in AN nutes, but haven't touched it since starting MC. i don't really track ppm in MC though.
i know a little camag will help keep me in better nute balance, and it will bring a little N, both of which will have dropped since i cut back the base MC by 4.5g. i'm out to lunch on the math though. since this was cobbled on the run.
which is why i tagged
@farside05 and
@Mr. Sauga. they actually dive deep in to this stuff. awesome stuff. my head hurts a bit.
anyway i kept rolling with hammers, and dropped 3mL of 2-0-0 cal mag in to the bin.
gave me 1000ppm on the nod. we were running 3ml before, so i let it ride. i was shooting closer to 900 on a guess.
at present this gives a mix at :
8L RO
2g BE
8g MC
3ml calmag
i can probably roll a half g back on the MC or BE to get me closer to 900. probably the MC if i keep the cal mag. not sure i want even to pull back though. they've run harder on nutes than i am comfortable with all through.
i need to keep a read on the plants over the next 48 to see what happens here. i can adjust between the BE and MC if it proves too hot. or pull back on everything as well.
got rid of the most spent leaves and fed them up.
they didn't get a 2 wk post flip defol, but no where needed it. after pulling out the spent stuff they were cleaned right out. they did not fill in after flip at all.
tops show some promise. it's gonna be a ride no matter what. really hope i can pull this off .
added a couple open buckets of water to get the rh up a bit passively. everything is stubbornly at the 25 -30% mark which is where we are at ambient everywhere. i'm eyeing up an adjustable fan to see if i can't change the environment a bit in my favour for the jungle room.
