After redoing my reservoirs following your recipe , I got my nutrient solution to mid 500's.....


Feeling so much better now. My PH stays fairly consistent, hovers around 5.6 5.8.... I noticed last night that the very tips of some of the fan leaves were white/ish .... I new I had to get the nutes right or these two would eventually croak too...
The small one has brownish looking root tangle on one side and whiter looking roots on the other. Will post some pics after I take the kids in from playing outside. The big one looks better. They don't look no where near as full and massive like I see in others pics, but these are still small I suppose.
I'm wanting to flip the lights soon so that these will be "ready" for my birthday in a couple months. I didn't intend on growing these big . This is just an experiment to see if my thumb was green enough to step up to DWC. So far , I'm already planning on going full bore with the next go around. Will be adding a helluva lot more light , and a bigger vent fan. I don't think this 4" fan that came with this kit is quite big enough. My box temps max out around 90Β° F ... Humidity is in the 50-60% range normally.
Gonna redo the interior with a reflective surface.
Thanks for the help Aqua Man and congratulations on your new position !
