wen u see ur first yellow leaves is a good time to start the nutes at low doses
i know they say u should change ur hps bulb after 3 grows lol, but ill wait to see how bad it getsMaybe its nothing to do with this but Ive been wondering if the CFLs loose power over time and thats why the second grow arnt going as fast? Coz you say yours isnt and mine isnt (but mines a different breed) and youre using the same CFL too? Its probably nothing but just something Ive been pondering...
