Sulphur Amendment in Hydro

I have recently learned that pro growers/alchemists advise to feed mag sulfate and potassium sulfate for added terps.

Given my current flower nute, I would like to ask advise about how much to add of those other chemicals.

Anyone can please advise?

i'd use just epsom at 1 gram per gallon with your nutes. K sul would give you way too much K.

thanks for the advice man

If you arent using RO water you will likely have enough sulphate in your base water. If you use tap water, the water company will usually provide a quality report which listts the elemental content. Excessive mag can cause issues with potassium especially in a recirculating res.
