Well in vegging under a600w hps at 24". I'm doing DTW feeding 8 times a day at 1300ppm. They are day 21 Northern Lights Auto. I'm at full strength on all the nutes.
@chefdave i saw your grow. I believe lol.View attachment 938799View attachment 938800

DAMNNNNN things move fast in this thread, hard to keep up!!!
For whatever reason I assumed you were pure hydro recirculating, those are the figures I quoted above and in Autotron's grow thread. B
ut if you're using drain to waste you can reduce strength 50% right off the start & stay there. At 1300ppm you're running way too strong and as it builds up in your medium it will start causing problems. DTW should be running 650 - 700PPM. Plus my comment of watching ppm's after feeding won't work with drain to waste. So be safe, dilute at least 50%, and watch what she does. At day 21 with a 600W HID you can lower your lights a bit, but until you get a good nute regimen going, maybe you're better to leave the light where it is and let the plants grow to the light. That way they acclimate to the light strength & nutrient strength.
Northern Lights.... Mmmmm, good weed! My first auto was an NL - Big Bud cross, wish I'd saved some.
