Man its been along time since i've updated on these girls. They seem to be doing well. I just started flowering, these pics are taken 2 days into flowering. Only problem i see is that i'm getting yellow top growth... not like nute burn but more like iron def (from what ive seen in pics). This happened the day after I switched to HPS and 12/12 lightning... was on 24/0. Maybe that shocked the photo on em and turned them yellow. They are getting better tho, as u can see its not extremely noticeable from the pics (lights were off, used cams flash so the color would be closer to what it should be).
I still haven't purchased a TDS/EC meter yet lol
. For the most part ive just watched the PH, water level, Temps (res and air). When the water level goes down i just make sure the PH is the same. If the PH rises and the water level goes down it tells me that the plant eating more and drinking less... so I add FULL str nutes to PHed RO water. I just top off with 1/2 str nutes solution and flush every week. So far this has worked pretty well.
The other problem I 've had is with Water temp, though its never gone up above 75... I usually keep it at between 60 and 70. But I hate putting water jugs in there all the time. Though i found a possible solution... yall tell me what you think.
Texas Hydroponics :: Environmental Control :: Reservoir & Aquarium Chillers :: Ice Probe Reservoir Chiller
I think this thing' will help me take my mind off water temps considering i'm using a 10 gallon res
But anyway, wanted to give yall an update and some input if your looking for a reasonable res chiller... I think i've seen one cheaper at an a Marine aquarium place btw.
Peace
