Good evening, we have recently set up a grow room running 4 x 400 watt lights over 6 plants. They are 2 weeks old from clone now.
The lights are running on 4 lumatek ballasts 400 volts with 600 watt lamps. On the ballast the minimum to run it at is 400 = 500 then 600. Which should I be running on and what’s the difference ?
The plants themselves look fairly healthy. I believe we were overwatering them for the first week. So have dropped it back to 1 feed a day.
We are running at ph 5.5 to 5.8
Then the chemicals at 1.2 to 1.4
Room temp is 27 during lights drops down to 20 ish during sleep.
I have a few poor looking leaves , should I leave them as they are ?
Any info would be hugely appreciated.
