Using pure blend pro / when to use cal mag?

[tintala]

I just switched to pure blend pro, however , it was burning my clones, so i had to cut back, but was wondering if anyone uses it and when do you start using CAL MAG? Seems this is what did them in?

so i guess you dont use it unless you are using RO water..just read...

I put Cal/Mag in the veg and bloom cycle w/o any ill results to the clones

Are you using RO water? I wonder if calmag should be used with regular water? How soon in veg , like right when clones go in?

so PIT:then would you say that one should use cal mag with PB due to the lack of cal mag in grow, i mean, since there is no cal mag in pure blend one should use calmag when using grow and bloom? They are supposed to be used in conjuction? sorry bout all the ways of asking this. lol.
thanks

Soft water is deficient in in calcium, so if you are using soft water, it's generally recommended that you use a calcium/magnesium supplement. Only use if there is a deficiency, hard water has pleny of calcium.
