Problem in coco coir

MickFoster said:

Not sure why growing in coco is being made so complicated?
I just feed one nutrient from start to finish daily to run off with tap water, a pH around 6.0, and an EC around 1.0 and I never have a discolored leaf all the way to harvest. No supplements.

I've succesfully run multiple runs with this coco & this nutes reaching 800-900g/m2. I moved to another location and cant make it work since april. I tried reverse osmosis water to discard the water but didn't help

Do you use nutrients with each watering or you do some watering with tap water only (let us take one week for instance), asking myself since I am just about to start first coco coir grow only.

My plants looked exactly the same when I used pre bagged coco. I could not figure the problem out and gave up after 3 tries. Went back to a soil-less mix.

600ppfd might be a bit much if your 18/6, and the plants looked hungry. Light stress will make plants look hungry too tho. Someone mentioned too high of an EC, I run 2.5 out the gate, never an issue.. My clones get rooted in 2.5 lol. But I make the mix myself and it could be a better balance that what other people experience issues with at lower EC values.

I always feed/water with nutrients........never, ever plain water.
I start in solo cups and start feeding daily to run off around 3 days from sprout.
I transplant to 2 gallon pots after 2 weeks and start feeding twice a day.
