Glad to see DG active on RIU, I've been a user of your products for years. With that being said, I've got some questions about Foliage Pro, Grow, and Bloom...
It seems like ever since I made the switch to LED's I've had to supplement additional Ca and Mg to avoid deficiencies. My understanding is that your products already contain these elements and shouldn't have to be supplemented. Have you ran into this issue before with LED's? Do you have any advice? Or do you think other factors such as lower temps could have an effect on Ca & Mg uptake?
My other question is this. If I were to fill a 20 gallon reservoir with 0 PPM R/O water, and I added 1000PPM of Foliage Pro, what would the breakdown be PPM wise of how much of each element is in the water?
