I don't like taking picture under hps, not good unless I cover the light or shut it off, pain in the butt!.
Added 3 gal of water to the rez replaced water pump filter and added nutes. Have to replace the filter on pump once a week. Found out that water level and quantity changes dramaticaly when roots grow and start taking space in the buckets. My system holds 12gal of water but I base all the nute calculation on a 10gal syst, that way I have less chance to overfert.
Think I'm going to prune some more fan leaves blocking light soon, because they're bushy as hell and the screen seems small now for the bushyness.
I came up with this simple way to calc nutes after adding water. Usualy I add 3 gal every 3 days so...I add only a 3rd of what I added when change the rez and usually takes me back close to where the PPMs were. So basicaly I've been eyeballing it lol! .
Going to be adding a second fan to see if it helps to bring down the RH some wich is 58-60%.
Temp 75f
Rez. 68f
PH. 5.7
RH. 59%
PPMs. 1650
Took the pics this morning with my cell. No way to make them big form the cell I'm at work. But not working hehe!
