I read if you get a decent amount run off no need to flush in coco is this true?
I do a res change every 2 weeks, at that time I flush. It might be more than necessary but it's to help prevent salt build up... when I flush I use a cleansing agent. I've been told never water just plain water, hence cleansing agent.
Coco doesn't hold on to the nutes like soil does, that's why it needs to be fed every watering.
Plants in coco show deficiencies quickly but recovery quickly as well.
I've been growing in coco for 3-4 years, I'm still learning...

Pick a schedule and stick to it and you'll never have to flush unless you fuck up. I water everyday with a feed-feed-feed-water schedule in coco hempy. Others like feed-feed-water. Find what works best for you.

Another piece of advice is keep logs of what you're adding and your readings, it can come in handy if something seems off. Start low with your feeding concentrations and work your way up. Try to ignore your nutrients recommended dosages, less is more - learn to read your plants.

No, just the cleanser. I use general hydroponic florakleen... come to think of it, you might be ok with just RO water, for your flush.
Flushing is hotly debated, I was taught to do so, so I do. Is it needed? I don't know but it hasn't hurt anything...

depends on the use of flushing. flushing at end to get anything out of buds is a myth. Most coco manuf. recommend at least 1 rinse,flush,salt removal,whatever you want to call it sometime in the grow as coco can hold onto the salt more than soil. and you usually feed more in coco

Right, the flush for me, is to prevent salt build up... nothing more. I just happen to do it with each res change (2 weeks).
Right or wrong it's how I do, as far as I can tell, It's not hurting anything.
I feed with every watering other than the flush, but I feed right after I flush.
Some people feed several times a light cycle, I choose to do so 1x a day. Could I do the microfeeds? Sure.
Again, I'm still learning and make tweaks as I learn more.

They honestly seem over watered to me, with the yellow droopy leaves. Also try and put some trays under them preferably with pot risers to keep them out of the runoff.
