I tried the Jack’s finish and it has that lousy blue dye in it too. My plants didn’t really like it and I hated watching my fans go synthetic blue. No calcium in it too, which was bad for me since my water is 55 ppm and has no calcium. WTF am I supposed to do for calcium at the finish, run the...

Yeah in 100 years they’ll be talking about how nice the weather used to be…

From Wiki In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their nuclei. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction. Now I’m not a scientist but to me it...

Gee I’ve never had the pleasure of having a choice? I must be getting older than I thought; we have synthetic pussy now? Please fill me in…

You’re right, all nutrients are chemicals. All things are made of chemicals. The air we breathe, the water we drink, everything is made of chemicals including every organic fertilizer. Everything is made of atoms from the periodic table, combined to make compounds or molecules, those are...

You and I were in another post and that came up I think. I’ve had some leaf drop week 5-6 of flower this run and I dropped my ph to 5.2 and that helped a lot. They really picked up the nutes at that ph and greened up a bit too. Not sure if it’s the best to stay there. Dangerous to get under 5 as...

I read about that, the medium’s vermiculite based?

I’m like @lusidghost, a hydro grower and I’m always trying to slow down my veg until I get my harvest done. Nothing wrong with being a soil grower though.

I’m new to Jack’s 321, on my second flowering run with it. It works well in my hydro setup, a bit of a tip burner for me but I think it’s PH related. Super cheap to run and the plants like it.

Did you manage to get rid of your HPS gear or are you still tripping over it like I am?

Here in Canada we usually say spelled not spelt. At least in Eastern Canada. Is that one of the 1738 words that are different? Are you from Britain and living in Canada. My neighbor is and uses words like spelt but I don’t know anyone who grew up here that uses it.

Yeah, hard to make a call, but weeks 4-6 are when most plants start getting nitrogen deficient, and 2 of those leaves are yellow and lime green. The plant could easily be deficient in other elements too. It looks deficient to me but I’m in Canada and don’t get to see any heat stressed outside...

That’s a real nice light @Cotyledon420. Never saw that style before, where the strips are run around in squares like that. Love the heat sink for the driver in the center. Nice Osram diodes and they have 75000 hours instead of the usual 50000. The efficacy seems low at 2.2, but I wonder if...

My root porn looks different….. This clogged up the return to my reservoir and I had fluid on the floor, so I had to chop it out. Plant’s ok though.

Canuck? Oh dear, are we responsible? Sorry….

Just a suggestion @surfgeo, but since you mentioned you were using a spare room, maybe you could keep using it for a dry/cure room. I made one last fall and it’s been working well for me. I put an a/c and dehumidifier in a room and keep the Rh between 55-60% and temps under 70, and that’s it. No...

Your plant is bigger than I thought it was, it messed up the scale for me. Carry on….

That EC shouldn’t burn up your plants like that, I’m up that high with Jack’s in flower in my hydro setup and I get burnt tips, but nothing like you have. How much fluid do you let drain through them? You never told us the PH of your solutions. Looks like nute burn from buildup in the coco or...

Those bags in the pics are 10 gallon? They look more like 3 or 5 gallons. 10 gallons should be fine through flower though, you’re right about that.

It looks like an exhale bottle with some kind of weed extract on the top of it. You didn’t put that there? Is it some kind of byproduct of the co2 generation?
