hey barry,

i use those same nutes by peters, its very strong so start using only 1/8th strength right now and only use it 2x a week at most.

if after a week she looks great move it to 1/4 strength and so on until you reach 50/50.

you plants look good so far but your going to need PH up using those nutes, any pet store carrys PH up in the aquarium section, its good idea to give your plants a good flush every 3 weeks or so during flower to rid of excess salts and other build up, when you flush use just plain water.
