Someone please tell me what is going on with her.. ive been feeding it an 8-6-6 for veg but the ph level is about 6 right now.. it turns to about 6.8 5 mins after i feed it but now its back to 6!! i noticed the yellow leaves and thought it was a nitrogen deficiency but maybe the PH has something to do with it?? anyway i was hoping someone could tell from these pics their guess on what might be wrong.. any input would be great i*** know none of you would like to see a perfectly good plant die, so any other things you might want to throw in i'd appreciate it.. this is my first grow!!!**
