I have 3 plants in 1 gal geopotsGreat to hear from you @Wisher2! Hope all is good your end.
Yeah the runoff situation has me stumped. Before any plants went in I tested the drip lines to get my flow rate, and from this I set the baseline for the timers.
All things being equal every plant should be getting 1gal per day from 12mins total run time, but clearly not everything is equal as the reservoirs empty at different rates. This is not relative to plant size or apparent consumption levels, and I can see no leaks anywhere.
The table furthest from the res and with the least number of plants - the 24K Gold - has the most runoff, but I think stoppering the unused halo lines after kicking out those males means the same water volume is running to fewer plants (3 instead of 5) and most of it is just running right through. I can't reduce the flow on the pump so I have just rolled back the feed time a little.
Opposite from the 24K and also furthest from its res is the Larry OG, which has almost no runoff whatsoever, not in 2 weeks since flip, and this 25gal res pumps out the slowest (i've refilled once a week instead of every 3 days). These 5 Larry's are heavy feeding plants that have stretched the most despite being the youngest in the room, foliage is lush and perky and bud sites are forming (nearing wk3 flower).
Dipping into the top of the coco I can tell it is damp but not moist, the pots feel light and there is no moisture in the table / hydroton layer. Those roots through the smart pots have dried back also.
On the face of it I would say they are not getting enough water, except the plants seem happy. What gives??
Should I up this timer and therefore water volume?? Perhaps not every halo is the same based on water pressure physics?

Tell me a little more about your setup: how big are they at third week? How much water do you average per plant per day?

Oh and about nutes: i'm nearly out of the GH Flora Series and although it has been fine I just know I don't have to crap around with three bottles multiple times a week. Working out my feeds every time is fussy and time consuming. I'm going to finish these runs and switch to either Peters' dry salts if I can decide on the NPK, or I read excellent things about DynaGrow's Foliage Pro and Bloom: single bottles, apparently cheaper, and run straight through.
a 15 gal reservoir
and each plant is 4' tall
they each drink .75 gal a day
it is my little tester box
my other space I run flood tables
I can run up to 5 plants @ 4' tall in the box
with cree 3590's run @ 2.1a
for nutes I run Botanicare CNS17 grow
Pure Blend Tea
and silica along with hydroguard
these are Landrace Affies I am testing
the one you dont see Is smaller ....I am testing the growth of an un topped from clone to 12/12 to see how it will work in a SOG. these 2 were topped once
the one on the right is Sativa leaning
the left....more stout and squat more Indica leaning
the sativa leaning went crazy once topped
the Indica lean......almost perfect 4 top structure
