Nutrient Lineup.

First grow DWC . Running 2 Galaxy Hydro 600w 4th Gen Full Spectrum Lights. 37 days old from Germination. According to the FF Hydro Feeding Schedule. I went full strength Big Bloom for week4 (3tsp/gal) I added 1/2 strength Grow Bigfor week 4 (1.5tsp/gal). And 1/4 teaspoon Open Sesame. Bottom of leaves turned yellow. My Rez temps were high.(trying frozen ice packs to control temperature ain’t workin) anyway so I flushed cuz the Rez startedt to stink. Mostly been just Distilled Water, H2O2 @3%, a tsp per gallon of water Grow Big. My question is what products that I have displayed would you be adding right now?

Actually, let me take some readings of my soup. lol type em in.

PR #1 Ph 5.6 Rez Temp 72* 744 ppm
(,500 Scale. FF uses 700 Scale. How do I convert?)

PR # 2 Ph 4.14 Rez Temps 77* 791 ppm.

PR#3 Ph 4.9 Rez Temp 78*733 ppm.

PR#1 - 744 ppm (Hanna 500ppm scale) = 1050 ppm (Truncheon 700ppm scale) = 1.5 EC

PR#2 - 791 ppm = 1120 ppm = 1.6 EC

PR#3 - 733 ppm = just under 1050 ppm = just under 1.5 EC

Those are all very high for a small plant. I'd probably start with half strength feed. Good luck.

I wouldn't use any of that stuff. I'd get some Jacks 5-12-26 and calcium nitrate.

That's the weirdest looking DWC set up I've ever seen.

Why are you feeding Open Sesame to plants that small in veg? Open Sesame is a high phosphorus additive 4-45-19. Oh I see you're following the FF schedule. That schedule will fry your plants.

Also that Big Bloom is going to yuck up your reservoir as it's made from EWC, and Guano. You might want to think about running sterile if you're having issues with temps and your reservoir is developing bad smells.

That's a whole bunch of shit honestly. Most of that isn't needed.

So much to unpack.

How does your grow system work?

Is that a net pot filled with rocks from the garden.

Is that even a net pot?

Pick a dry ammendment that you can get locally..or oder jacks...shipping is like 40$ tho.


Your nute selection is not the best for hydro and 100% not the best for hydro without a chiller. I would not put any of that in my res.


Pick a method to sterilize your res. H202 is ok...just expensive. I use pool shock. There are several ways to do it.

Ph is 4???? Should be 5.8 in veg. 6.2 in flower with a lil wiggle. Does not need to be exact but in the general area is ok.

You can find conversion charts online. But don't. Just use EC. If you don't have a pen that does ec...get one.

Ec should be under 1 for plants that size.

700ppm on the .7 scale is 1ec. So your at the right spot. Just all the wrong stuff.

Throw that feed schedule in the trash.

Thanks Krew. Prolly gonna start over
