Mint Jelly and purple haze in 2x2

It seems I've finally fixed the nute burn. It's interesting that both plants were incapable of taking over about 600 ppm. Once lower, they really took off. switched on the red colors this week to 25%, and will up to 50% today. plants seem to be handling the lights no problem. inside temp hasn't been above 78. switched to flowering notes. Just kept them very low so overall, PPM was about 500.
