whatup you guys this is my second attempt at growing so feel free to give me some critisism and feedback. i have a 4*4 6 1/2 tent with a 600watt lumatek digital ballast and a yield master 2 hoiod. im doing 20/4 schedule. doing GH micro,bloom,grow nutes. ppm is at 360, temps are 70-82. humidity is 34-56 percent. 9 plants. 3 fireflies, 3 blueberry hogs breath, 2 alien ogs, 1 fire og. i think i have some nut burn on the fireflies and alien og. i think its because my ppm is to low for 9 plants and i should up the nuts. i have a 30 gallon res but am only using 15 until the get bigger. this is my 2nd week in veg and plan to flower on 4th week. please look at my plants and give some advice. i flood the table 4 times a day for 10 minutes each and it takes 8min to drain. im using 6inch net pots with coco plugs and hydroton clay as media. roots are popping out of the baskets now and look clean and white!
