That many plants won't fit properly in that amount of space.
You'd need 3-4 8 bulb t5 and still not have that pro sheen to your buds.... Just get hps probably 400w in that space with cool tube I was planning to put 600w in 3x5x6 closet but was worried about temps so i got tent.
think maybe...
Give them nutes or they will die not a lot though I can only assume you have some sort of feeding guide . You're ph is staying high because that's the natural ph of your tap water(or there abouts) when you start to feed it should chill out a bit.
