I’m using Jack’s 321 with Ro water, What should I shoot for for my ec32 gal water in 17 gal tubs in 4 totes. @Myfriendis410 @Growdoc @Bamarayne @ peachfuzz @

I run 1.4-1.5 most every feed, may bump up first couple weeks of flip. I try to maintain 1.8 runoff, or close to it. With totes and no runoff, I would start at 1.5 because they will eat the nutes out and EC will start to fall unless you stay on top of res EC.

I’m running Canna nutrients and i go for an EC range of 1800 to 2000, TDS of 900 to 1000 and my PH at 5.8 to 6.2.
I do this for the entire grow except for the last 2 weeks. I just let the ladies drink up all of the nuts in the system. I hate wasting it lol.

You can run full strength Jack’s from beginning to end. Don’t forget to add silica. I keep my TDS at 2.0 to 2.2 except for a three week jolt of P and K at transition. That bumps it up to 2.3 or so.

Do you add extra cal/ mag at any point @ My friend 410

No; never saw signs of a def. Canopy stays green until harvest too which I like.
