Hey dude.I like the fact you invested in your stuff ,good seed strain and equipment will erase many mistakes.Your PH is F'd or you have nute burn big time.So flush like everyone here is saying and go easy on the nutes ease them back with a nice balanced PH and they will be fine.All your equipment is excactly the same as mine but i use General Hydroponic for nutes and for flower i use Plant prod 15-30-15.Also i do not use Fox farm for soil .I like either a bail or two of Sunshine #4 or Promix HD and i add nothing too this.All ready too go airy and light through the whole grow.Your temp if using a 1000 watt hps might be high.I have two Lumateks and run a 600 & 400 watt hps on either side of my large closet and the temp is steady at 85 f and my plants at 3 weeks flowering are frosty and already getting dense and huge.I have 3 God bud females and 6 Dynamite females.Grow Dynamite strain from Next generation seeds.The yield is huge and the stone is f'ing nuts couchlock ,Indica bus stuff.$75 for 10 seeds.Anyway try the soil i suggest here next grow you will be very glad you did.I'm on my 3rd grow and all have turned out totally perfect.The 1000 ,if you don't mind throwing a couple more bucks down i would use a lumatek 600 & 400 instead of the 1000 lumatek and bulb.I find you can drop them horizontally and the bulbs you can get them fairly close too the canopy.Good luck man. Peace
