Has anybody tried jacks ro 12-4-16 thru veg then switched to jacks 5-12-26 thru flower without the calnit? Or switched and went back to ro formula till end. I’m in Rdwc atm. If so what was your findings. Wanting to boost P up just a hair. So far so good on the jacks ro in veg. Thanks in advance.

Why would you leave out calnit?

If your looking for a lower N formula for flower there are Jack's 0-12-26 and MasterBlend 4-18-38.

You need calcium. And you need more N than what's in jacks 5-12-26 unless you're in the last couple weeks of bloom. Still need the Ca tho. Ppl use either calcium chloride or gypsum for just Ca without added N.

Thanks for the reply’s. This would be Just for flower. would like to lower the N. Up the P a bit first couple weeks would be good. I looked at the no N formula. Guess I could call jacks. But I do have some 321 still and calnit. Grown with it all the way thru quite a few runs but switched to hydro formula this time to try and see how it did with less N in flower and with 100% ro water. Havnt tryed the 10-20-30 for a week or 2 to see how it does. Idk just trying something a little different to see.
