1st time posting! With pics!

Wasup everyone. So i've been growing for the last year and still learning. Any help or tip would be great! Anyone can explain me how to use the ppm meter (Pic)?

Veg Tent:

6.5'x6.5'x6.5'
(2) 600w MH

(1) Green Acid (Clone)
(1) Madness (World of Seeds)
(5) Morning Glory (Barney's Farm)
(1) OG (Clone)
(2) Platinum Bubba (Clone)
(1) Purple Kush (Clone)

Nice setup. I don't know how the PPM truncheon works but I have Bluelab PH and PPM pens and they are the shit. Just remember to calibrate every two weeks to keep it from drifting.

Good luck and keep it green!

Nice looking setup and that green acid is crazy looking with the 3 blade leaves.

Thx bro! Why some times there are 3 blade, 5 blade, 7 blade leaves...?

Welcome! Nice gals

looks good man proper set up!!!!!
