The Setup:
4 bucket RDWC
4 x 4 tent
Mars Hydro TS 3000 light 80% strength at 30 inches from plants
2 air stones per bucket
Water chiller kept at 65 degrees
General Hydro nutrients measured in 24 gallons
Micro 120 ml
Gro 120 ml
Bloom 60 ml
Rapid Start 60 ml
Floralicious plus 24 ml
Armor Si 24 ml
Diamond Nectar 120 ml
Flora Blend 120 ml
Calimagic 60
Using RO water
Temp between 75 - 80
Humidity between 40% - 50%
PH kept between 5.5 and 6.0
These measurements are based on the General Hydro feed chart generator. https://generalhydroponics.com/feedchart-generator
The plants are 8 weeks from seed, and have been manifolded for 8 colas. The net is just there for support more than scrog.
Through most of these plants lives it was a constant game of keeping PH down, and PPM up. For the past 3 weeks their PPM was around 920 (I was actually adding 28 gallons worth of nutes to 24 gallons of water) and would still go down. I think what happened was since the heater in the house kicked on the temps in tent went up and they just drank more water than usual. Before the tent was at about 75 degrees but now its running between 78 and 79. So yesterday I did a nutrient change after about 6 hours of flushing mixing it at the measurements above and a PPM of about 770. Today the ppm was 780 so added some plain RO water to bring it down to 750. My question is if 6 hours was enough? The PPM of the runoff water was about 40 so I am fairly certain I got the buildup out, but if it has nutrient lockout should I flush longer? Right now the only signs are that the leaf tips got the tell tale sign of burn, and new growth has some yellowing from the inside out. So it seems the nutrient burn probably caused some lockout for immobile nutrients. I am curious how long nutrient lockout has lasted for others using RDWC? I was going to put these guys into flowering next week but not if they are locked out.
