Thanks for the compliment JohnDee. Admittedly I began in soil and yeah, so I guess I have a few bad habits to break yet (ie pot lifting). Anyhow, thanks for the different perspective and an opportunity to learn a little something new. Ya'll have a great Holiday weekend!

Why not feed at higher ph, like 6.5?
That's a good question...I'll offer my thoughts.
His primary issue right now is a build-up of nutrient salts in rootzone.

Everyone recommends ph 5.8 to 6.0 for coco. I don't know if 6.5 will cause any problems. But he's not going to change the ph of his rootzone significantly that way. Only runoff will do the job.

On the other hand, as a temporary compensation...it could help with nutrient absorption. Give it a try. It's a reasonable suggestion.

This page says adjust ph in based on ph out, but some people here said differently. https://www.growweedeasy.com/ph
I had low ph in a coco hempy bucket from excessive PPM, and experienced growers said they don't pay any attention to run off ph, but they do monitor run-off PPM/EC.
I've seen a lot of recommendations to vary the ph, like 5.8 - 6.2, but I have to look into ph for coco more.

Edit: Just found this while searching the net, "Save your sanity, don't test run off in coco"

1600 ppm is to high for coir unless your running heavy lighting and Co2. 6-650 ppm (1.2 ec) works good for me with single daily feeds and a little less when multi feeds a day.
Noted, thx. Ok watered this morning with 980ppm and got 615ppm runoff. Gonna keep it at 600ish and monitor.

I think i am pushing them hard on the lights
Led at over 40w sq ft.
350w for a 2’x4’ tent
No co2, lights are about 20” to be safe

You can run much closer with strips. 44w/ft. is probably too much with such efficient lights, especially for a 1st grow. The normal recommendation is 30.

Have i got a deal for you, ill post in detail in a bit. Its called the ppk method or Passive Plant Killer method. Its not passive nor does it kill plants! Cheap, easy and it turns coco to hydroponics. I love it, but gunna take min to detail out, as soon as i head to the smoke room for the night ill give you the details.

This method turns coco into hroponics plus. I can set up a one plant rig for about $25, and numerous tweaks and mods can be done to fit your needs so grab the substance not every detail.

Shit needed:

Appropriate sized laundry basket
Weed block landscape fabric
Electrical tape
Small fountain pump
Tubing
Throat pice for sink drain
10 gallon low profile tote
Tennis ball plastic sleave and lid
Plastic epoxy
Timer

Now take the tote lid and cut hole for throat piece to slide in. Cut hole size to tennis ball sleeve and cut a chunk off bottom of sleeve, epoxy it in, it will be a filling hole. Drill hole for the pond pump tubing in lid.

Now cut hole for throat pice in bottom of laundry basket slide throat piece in and epoxy it to bottom of laudry basket as if the laundry basket were a sink, the thoat piece is a drain just as if it were in a sink. Cut chunk of weed block fabric and electical tape it tightly with many winds to cover the bottom of throat piece like a sock filter... now line the laundry basket w two layers of weed block fabric slicing an "x" over the throat piece hole.

Sit unit on top of tote by sliding throat piece is throat piece hole making sute it doesnt bottom out. Make sure throat piece doesn't bottom out in tote.

Place pump in tote, run line out to a halo to or make a water halo out of the tubing by putting bolt in end and drilling bunch of holes in the last foot or foot n a half.

Fill clothes basket w coco and plant plant it making sure coco gets to bottom of throat piece. Run your halo around stem staking if neccesry. Run pump to timer. I run mine 2 mins every two hours but theres many tweaks one could do there, more frequent less run time etc.

I fill mine w jacks 321. Which is close to equal volume jacks hydro and calnitrate and a pinch of epsom if u choose, stuff is crazy cheap and works great but any hydro nute wud do. I mix mine weak, half dose max which is 1/2 tsp per gallon, i dont ph but its 6ish.

Im telling you they explode in this! If pump fails while away the plant can wick water and the constant bath keeps fresh oxygenated water/feed to em, 24/7. Im three rounds deep using this method. In unscientific but not sloppy side by side the plant in this container was about 1 and 2/3 the plant that was in coco treated like soil was. Makes life so easy, just fill the hole now and again and they rock, within a week transplanting em into it youll have roots growing out the side of the weeblock lined laundry tub, theyll aerotrim but ull see em poking out, and when i clean up at end i have 18 inch roots that worked their way through the weedblock and are sitting in the res...

If you have more than one plant you can daisy chain the toats together with just tubing barbs and tubing between em, thats what i do, my room is small i only water the one by the door and it shares with the rest.

I never change the water just keep adding fresh.

Id never grow another way again, lightens the workload of watering 10 fold and they grow faster than hell!

i only do this in flower for now but im having to cut my veg size or they overgrow my flower room!

I’ve read about it a couple times I guess my mind couldn’t wrap around always wet coco and the plants not being overwatered
They love it! mine are SOAKED 24/7. Overwatering is an oversimplified term really for a symtom of roots lacking oxygen. In soil or peat a dry cycle is necessary to get that medium to draw oxygen in, coco retains oxygen even fully saturated and method i use brings oxygen rich water repeatedly daily "flushing" out the oxygen depleated water that was in there, though coco holds enough it doesnt need that constant fresh water, feed mix, but im telling ya they love it when you give it to em.
