I water brand new seedlings with the exact same mix and I don't change a thing all the way through to the chop. If you want to flush at the end, do so, they will fade quickly.

This is exactly what I do and it works great.

Correct

Like I said before it’s the tupar that’s the issue bro. Try it compared to pure coco. I’ve had great results with tupar in the past but again there are inconsistencies from bag to bag. Jacks 3.7 calnit 2.5 epsom 1 gram all per gallon should work great.

To me anything over 600 ppm (1.2 ec)is a waste in coco. Most of my veg feeds are 400 ppm or less, flower 500 ppm or less.
And once you learn how to feed your plant a balanced diet you'll find you don't need to feed coir to run-off every time. I do whole grows with coir with no run-off.

got everything sorted out and now they are recovering nicely. bad coco with a ton of salts in it caused lockout and then it presented itself with deficiencies so i answered with heavier feeds. got worse and worse until i flushed the hell out of them and gave them a restart and moved them from 1 gal to 3 gal pots in a new clean brand of coco. the roots are coming back to life, the plants are getting green and healthy all around. still a little light and deficient but night and day difference. flowering on the first if they keep this up. now i have to build my scrog frames and mount them to the light framework and hang the trellis netting.

thanks for all the input everyone. id like to urge anyone having issues to check their runoff for inconsistencies. i knew as soon as i saw the runoff ppms. i was on the brink of giving up, killing everything and starting over. contemplating quitting all together. bad juju all around. i felt cursed and like everything i did was failing, especially after my failure in the other garden due to overwatering after transplanting. damn near killed everything and had to blast everything to save it. now im coming back harder than ever. PPK is getting cleaned out and revitalized with a vengeance!

Glad to hear it brother how are you feeding these are they being hand-fed or are they on a timer pump setup

blumats doing their thing
600ppm jacks and calnit. right now i am doing a 1:1 ratio to supplement extra calcium and green them up.

I gotcha. I'm showing lockout overfeeding symptoms on my room right now. I flushed with 300ppm and I took my feedings from every 5 hours back to every 12 hours I don't think my root structures are big enough to support the 5 feedings per day yet.

You can't really overwater / overfeed coco. Even when you over do it before plants have established their roots, the only consequence will be slower root development.

Think of it this way - If you're doing DTW coco right you're basically using the coco to hold the liquid and the roots upright. That's it. You could grow the plants directly in 100% nutrient solution if you wanted to. It wouldn't cause burning or 'lockout' or anything like that.

Until the end of flower you shouldn't ever 'flush' with anything other than normal full strength nutrient solution.

It may not be overfeeding but it's certainly salt buildup. I know this because I flush with 300ppm water and runoff is 400ppm... the last time I flushed the runoff would drop .3 to .4 ec per watering telling me that my plants were consuming that much. Now runoff is higher than the input.
