So i decided to start this with an email i sent to advanced nutrients copy pasted (plus a few extras pics
I have a 40 GAL reservoir (Pic #1)
And 4 grow buckets that retain about 4 GAL being filled and overflowed constantly (pic #2 & #3) Totaling 56 GAL
I am following the calculator and on week 6 so about 5FL Oz per 10 GAL of Connoisseur Grow A & B
About 2.5 FL Oz Per 10 GAL of B52 (Pic #4)
When i change out the reservoir i shut off the return to the reservoir and open a drain valve. (pic #1)
When the reservoir is empty i shut off the feed pump for the plants and fill 40 Gal into reservoir threw my sample bucket (Pic #5)
The sample bucket just circulates water between the bucket and the reservoir for water tests and adjustments.
I add my nutrients to the bucket one at a time starting with B52 then connoisseur Grow A and then B
i Let it circulate and irriate in the reservoir for about 30 min then i turn feed pump on and the the first 5 GAL drain so the old nutrients in the buckets is at least partially drained but out of approx 56 GAL i am replacing approx 42 GAL with fresh nutrients i turn off the drain and turn on the return.
RIght now the issues im having are with a spotting on older leaves (pic#6 #7 & #8)
it is only showing up on 2 of 4 plants at the moment … and my best guess is a calcium deficiency
and also the ph Starts at around 6.2 after a res change and goes up from there
source water is from R.O. and is 21 PPM and PH 6.02
air temp 76-78
water Temp is 68
PH is up to 6.4 and 2 HR old… (update… it has been 48 HR and ph is up to 6.7)
1000w MH 2 1/2 ft over canopy 20hr on / 4 off
each grow bucket has a 6 inch air stone disk
CO2 has Just been turned on @ 1500 PPM
I have not started managing humidity yet.
Any advice, constructive criticism or socratic debates would be most welcome.
AMA except who i am 0_o and dating advice… i dont know the answer to either of those
