anything after 1200 is pretty much wasting chem's in veg,they may tollerate it....but its a waste of money.
divestoned Reviewed by divestoned on . are my ppms alright? My plants are now all about 2 feet tall, Still vegging them for 2 more weeks. I raised my ppm level from last week 1240, too 1440. Is that to much? I changed it last night. Rating: 5
