Light/heat burn and mag def?

Thanks for chiming in. Any tips about fertigation? Using 5L pots atm (2x2' area each). I'm not sure how many times per day is best.
1 or two emitters per pot should be fine; I run a faster speed pressure compensating drip emitter (10 GPH) whereas alot run slow (.5GPH), id suggest medium to fast drip speed, with short burst feedings. I fertigate as often as I can while minimizing nutrient runoff and making sure plants roots are not waterlogged (prevent waterlogging by undersizing the pot and getting the plant rootbound, [once its rootbound you actually cant overwater it if using coco; I know it sounds counter intuitive, but been doing this for years.])

and feeding at least once per hour, off at night, to become a true "pulse-feed" system. I currently fertigate 12 times an hour in flower. You just have to be there for a while to adjust timing for a while until you hit the sweet spot; but once its setup you can leave for a week or two vacation and comeback to a healthy garden.

Yes this is what I want, a system I can leave for days :D right now I'm feeding by hand every 12th hour.

They look pretty good, healthy; way too many tops, prune em off now. Say about .75-1 oz per top so only allow how many tops you need to get your desired yield. SO if you want 1 pound create 16-24 tops, prune off most everything else or get tiny larf nugs an no good solid buds. Get them on the drip ASAP even if u just drip in the same way you hand water, once or twice per day, you'd still see huge benefits in growth and less labor for you. Ive added drip as late as 3.5 weeks in flower and still noticed a huge boost in yield/growth from that late of an installation

super easy, brute 50 gal can for res ( I have mine on castors for ez moving), ~400 gph pump, tubing, a dozen or so emitters, and a timer. BOOM. can add another pump to flume/aerate too but not necessary in DTW

Should've mentioned that I found a way to make the system and is almost done :)
Got a 1000gph+ pump that can be adjusted. Planned to use that for this kinda system.
Let's just hope seal's hold

you might be overcomplicating, but looks neat. its drip, use 1/8" tubing. Any deficiencies you might have, Mg included, become much less common with automated feeding

if its too small use more than one dripper ;) I run 2-6 1/8" lines to a 3-10 gallon pot. 1 1/8" line to any 2 gal or less
That would solve it.. But thinkin about it, I can actually use this for rdwc waterfalls when the time comes :) also thinking maybe I should just screw in 4-6 "sprinklers" in this one for best distribution.

I was thinking that would be good waterfall for DWC when i saw it. In my experience distribution only becomes an issue when using 7 or more gallons media. and even then I use 6 1/8" and I get 2lb trees with zero handwatering. 1 single 1/8" emitter can supply up to a 2 gallon pot. Ive been working with drip in multi light perpetual systems for years. Coco wicks water well, use that to save on equipment and labor
