I just noticed a couple brown spots on a couple leaves and the tips are burning.my ppm is 650 so im just wondering if thats to high or what is the best to keep her at? im using gh flora nutes grow,micro,and bloom.I just checked my ph and its high its at 8.6 but its been around there this whole time with no problems as gh nutes have ph buffers and everytime I lower the ph I seem to have problems.Im just wondering if she needs a higher ppm(more nutes) or to lower it? I noticed some of her stems are reddish-purple also so is she locked or out in need of more micro nutes? Im new to hydro but i know in soil that she has a def more than likely for micro nutes.
