This is my 4th crop and I'm still scratching my head as to what is causing the problems. I'm wondering if there's something in the room off gassing. (see pic of equipment in room)
They're less than 1 week in and already showing the same signs as the previous crops. Little to no root growth and new growth starts drooping and older leaves start yellowing.
Sealed room with CO2 @ 800ppm
Consistent 69 degrees in the room
55-63% Humidity
Weekly calibrated Nutra Drip Tri Meter Reads:
PH 5.7-5.9
430ppm (using just well water reads 210ppm which comes from red clay dirt and is a little high in Fe)
Reservoir Temp at 64 degrees (I just added a heater last night and brought it up to 70degrees)
Highblo 80 is aerating the res using air from outside the sealed room
Recirculated top feeding into rockwool. I decreased from from 4min every 2hours to 1.5 minutes every 3hours when I noticed the drooping but they haven't picked back up.
5x1000 HPS water cooled lights
Just switched to General Hydroponics nutes from Sensi A&B
