Ya no doubt there no food left. Feed them as you would maybe a little more since the flush. as far as ph. I don’t know what to tell ya. Feed them some calmag and let the plants tell ya if all good.

Will chalk this up as an I don’t know why. Lol. I wouldn’t bother with the rest. Just continue to feed around 6 and see.
 
My only idea is the pebbles are saturated with pH and it would take crazy amounts of water to flush it down. Never using them again. 1ml/100l of calmag?

I've taken a few photos. They are only pale because of the mh bulb and my camera is shit so can't even take a decent one without the bulb but they are healthy green colour. What do you think of them? 5 and half weeks old
What do you think about the plants?
they look ok. Shitty pic though. Looking at the amount of pebbles.geez there’s a few isn’t there. Nothing you can do but keep on keeping on. Lol.
 
Probably too big a pot for such a small plant. Hard to tell. But looks like not enough fertigation.

It's my first time and I've read it's better to go with less than too much, but according to the chart I think it's safe for me to try 1100 for a few days and observe, if nothing bad happens then increase.

That was for the other guy. But ya in your case increase small amounts and observe. That’s the beauty of coco they’ll respond quick if it’s bad lower EC and flush it out. So easy.

With my 1-2-3 nutes. Powdered from my local hydro. I’ve been playing with more 3 then 2. 2 is my N.Some of my previous hydro crops after 70 days of flower the leaves are dark green like they’ve been armour alled lol. So been reducing N now. If you’ve ever read about lucas formula does kinda the same thing.
