Hey Boss, you have two sets of leafs,It's time to add 1/4 the strength nutr.I use GH 3-part nutrs.They have a feeding chart at hydroponics.net go to the bottom of the page and click on learning center.there's a ton of infor and the weekly feeding charts and more.
To calibrate your pen you will have to buy the calibration soluition,4.01 & 7.01.You cant use your nutr solution to calibrate with.On the pen there's two trim screws,one for the low ph 4.01 and one for the high 7.01.You put the pen in the 4.01 solution and turn the screw and the same with the 7.01 sloution.Now it's calibrated.You will do this about one time a month ,just so the pen will give you the right PH reading.To have a early and late crop just start one and 5 weeks later start the second. Best of luck to you. PEACE
crazywill Reviewed by crazywill on . WATERFARM/ BLUE MOON ROCKS & PAPAYA Hello, once again everyone. I have something else that I'm interested in. BOG's Blue Moon Rocks and Nirvana's Papaya are my two latest projects. I want to start a mom of each strain (Veg/Clone Room). Afterwards I want to create a flower room for clones. Not sure which hydro style I want to use (DWC, Flood & Drain, Aeroponics, etc.). I would like to have two seperate tables (Early Flower and Late/Harvest Flower). I'm thinking about using 2-400 HPS or 1-600 HPS, but I'm not sure. Any Rating: 5
