Dolomite lime for soil?

[Cp420]

Ive been having alot of cal/mag issues with my plants ive been using liquid cal/mag and its just doesnt seem to be enough.in veg state they grow well but once i start flowering its like i cant keep up with what the plant is taking in even though ive added enough cal/mag to my water to kill an ox! So im wondering if adding a bit of dolomite lime to the soil is a better solution instead of the liquid cal/mag?

Sounds like you were more likely dealing with lockout if excess liquid CalMag did not solve the problem.

Dolomite can help buffer soil, but the dose required is no easier to get right than is the dose of CalMag. Further, just about any prepared soil mix you buy will already have dolomite lime in it which makes dosing even trickier.

If you have decent photos of the problems you have had, asking about them in the infirmary by filling in the form would be your best bet for helpful advice for the next grow.

Good luck with it.
