How To Flush Without Emptying Resevoir

[iloveplants]

I have a 200 gallon tank that waters 4 different tables...there are different strains on each table. My super lemon Haze look like they have nitrogen toxicity....I need to flush, but I can't just empty my tank, fill it with RO and flush. That would not be ok for the other strains. I can disconnect the one table from the tank, and flood the table by hand, but I can't do that manually six times in a day....plus that would screw up the nutrients in the tank big time. So if I flood it manually ONE time would that be sufficient? Or can I switch to spraying foliar waterings? The buds are small and there is lots of air flow and circulation, so I think they'd dry quick...and not have a mold problem...any thoughts???

So you can't flush them all bc you don't want to waste the nutes? Or bc you are afraid to flush the ones that don't need it?

I don't use flood tables, but I flush plants for weeks at a time in chlorine free water (not RO, just tap water with the chlorine bubbled out) Most plants respond well to a good flush, I'd just flush them all and then adjust for the SLH.

But wait for a flood table person to confirm.

This is why you should run different reservoirs for each table...

Can you just flush the shit out of them once by hand?
