Hi Ive been trying to show off the displays of my various grow methods in my smalltown shop and Ive been having some issues with my tomatoes.
Their turning yellow, but I havent given them many nutrients. I just tested their soil (SS #4) ph and it was 6.28. I have it on a light rail 3.5 with a lumenaire 6 reflector and 400w MH bulb. I was wondering what I could do to perk it up?
any suggestions?
