Nute question for Hempy; NSR Greenleaves

I'm starting my first hempy grow. There aren't many choices for nutrients around here and shipping is a real pain. The local hydroponics shop had a few options. The two kinds that were available were a) General Hydroponics 3 part mix, and b) NSR Greenleaves Grow Juice and Bloom Juice.

I picked up the Grow Juice and Bloom Juice.

Has anyone used the greenleaves products?

If so, do you have any pointers for using it in a hempy grow?

Anybody use these nutes?

I have used NSR Greenleaves for some time now with satisfactory results. Hydroponic grow system with careful attention paid to ph levels.

My latest grow started off fine with NSR Grow Juice. I switched to a new supply of NSR Greenleaves Bloom Juice for the flowering phase. My grow turned into a disaster as leaves started to turn yellow. I believe the problem is magnesium deficiency which was never a problem before. I added epson salt to the mix which stopped the yellowing of leaves but i do not think the yellow leaves are going to get back to green. The only variable I can put the problem on is the new batch of NSR Greenleaves Bloom Juice.

NSR Greenleaves is hard to find online and now I see why. I do not recommend NSR Greenleaves. I have to assume that they messed up when they mixed the batch of NSR Greenleaves Bloom Juice I got a hold of. I also note the NSR Greenleaves has no online presence which makes it difficult to easily register complaints.

I have the same problem. The NSR Grow works fine, but when switching for bloom phase, after a few weeks I have encountered a Magnesium deficiency as well. This problem hasn't yet been taken care of, and was the reason I started searching for a different nutrient brand.
