GH MaxiBloom, Cal and Mag

When using RO water with GH MaxiBloon do you think i should add cal-mag? On the back of the MaxiBloom package it says it has:

ca 5%
mg 3.5%

i ask this because any time you mention ro water, people say you need to add cal and mag.

thanks

forgot to mention that I'm in hydro ebb&flow buckets

When using RO water it is a must to use cal mag even if the nutes that you are using has cal mag

yeah it is expected to ad 10-15ppm of calmag to r/o water

question any pics of nugs with that nute line curious

sorry no pics, i just switched from soil to hydro. And this is the only nutrient line I've used in hydro. But i didn't think i was doing all that bad in soil. But my ebb&flow buckets are blowing away any soil I've done.

definitely will. ebbnflow is the best in my opinion i use advanced nutes but wanted to check a cheaper line used in an ebbnflow

@5grams per gallon theres 46ppm of Mg and 66ppm of Ca in Maxibloom. Im not sure of hydros requirements but id definitely add some calmag which will also more then likely add to your N too with calcium nitrate and magnesium nitrate as main ingredients in most calmags on market. I like botanicares calmag plus if i had to pick one of the many bottles out there.

I've been using it about a year in 5 gallon DWC. I like it, its easy to use turns out good. You might want to try some maxi grow with it and the kool bloom seems to really help bulk it up, the dry kool bloom sucks. In flower, i use two small scoops of maxi grow, two of maxi bloom, and a little liquid kool bloom.

I think one of my plants is having a cal mag issue. I use tap water but it is only about 44 ppm out the tap. Not sure if its a cal mag issue or ph lockout.

not a bad pic of the nugs thanks.definitely a nute problem with to much salt or ph but it looks like there is a salt build up preventing the leaf to bring water/sugar intake and thats why the tips probably burned first the the middle part by the leaf veins were next.
