snowryder leaves turning yellow and curling up? wtf is going on?

hi, first heres some brief info on my closet grow:

2 snowryders in 6in pots
175watts
miracle gro soil
fan
always 80-88 degrees

im about 2 weeks in. both my plants started out ok, but lately they have been turning yellow and its just getting worse and worse. one of them have turned yellow and the leaves are curling upward.. i water about twice a day, morning and night. and normally the soil looks dry so i doubt its overwatering. my guess would be the pH level. wat do you think? sry no pics..

someone plz help

take a pic and post brother, yellow leaves can be a few different things from heat stress, nute burn, micro nutrient problems, ph, light bleaching....
Take a second and post one and someone will likely be able to offer constructive help but I'd want to see it to offer good advice.

cowell said it best

I'm with the above poster, get us some pics........also twice a day is too much. its probably nutrient burn caused by watering so much. your more than likely releasing all of the time release fertilizer in the MG.
