Well my plan was to go to 100% bloom but since the leaves are turning yellow I figured it was a Nitrogen deficiency so I thought I would add a little just in case. My bloom has 2.5 and my grow has 3 so its really not that much difference in the Nitrogen content. I will try raising the PPM a tad with bloom nutes and CalMag+ and just monitor it over the next day or two. I really don't want to flush because its such a pain and I just changed the res yesterday, but I guess I will have to if the problem doesn't turn around.
