Deficency, Ph Issue, or Both?

Currently growing in rock wool cubes using the Lucas formula + CaMg + Microbes run to waste, feeding low 200ppm and 5.8ph due to signs of burns and color loss. Could it be not feeding enough or is it something that I am lacking? Heat definitely isn't an issue or lack of light. Any insight would be much appreciated, Thanks for any input in advance!

If this is a wide spread problem on your plant(s) then I'd say it looks like Nitrogen isn't getting to the plant. If you're running some heavy wattage lamps, 1k or even 600, you need to make sure and give them consistent feedings. A little bit, all the time, rather than a lot every once in a while. Of course, the leaves that turned yellow can't come back, so best you can do is stabilize it. Rock wool is inert, don't forget. I'm a soil man myself.

Appreciate the info brother man I check to see how heavy the block is at least once a day to make sure it stays heavy and rarely give it more then a half gallon per day, ill try uping my nutrients gradually just don't want to burn it. Thanks for your time!
