I’ve been running Athena Pro Line for probably 10 months with HPS lights in flower, cmh (3k and 4k in dual 315s) and HPS in veg.
Was running 2.0 EC in veg and 2.7 in flower, just like the heavy chart.
I’ve bumped it to 3.0 veg 3.0 flower. I just harvested the first room I ran 3.0 EC in flower on. Don’t know the weights or have COAs yet.
I have a mono crop of White Truffle on day 25 at 3.0 EC, but was running 2.0 in veg.
I pour an entire 25 lb bag into a 30 gallon res with 25 gallons of water and run Dosatrons.
I am running rockwool, but have ran 1 gallon coco fabric pots in the same room as the rockwool on the same feed and irrigation times. I did not notice a different or have any calcium issues.
Irrigation is .5 gallon emitters, 10-11 times per day, 3-5 mins per feed. Somewhere between .3 and .5 gallons per plant per day.
I do not check run off, just go off the plants.
Since going to 3.0 in flower I noticed you need to bump up the irrigation times after week three to avoid burn.
The run with coco and rockwool, the White Truffles were in coco and testing 5.75% terps. I’ve also had it test in the mid 3s.
I’ve have ran 9 plants under LED at home, pouring my 2.7 EC bloom feed from Dosatrons at work to take home. The plants were very deficient after week 3.
I’ve hear of people with LEDs running 3.5-4.0 EC.
