Buffering/flushing coco half way through grow?

I'm curious as my runoff is extremely low compared to what I'm feeding half way through my grow in at 1.9 out at 1.3ec and showing defienceys. can I basicly flush with full strength nutes until my run off is the same as what I'm putting in?

Or mabey just increase inflow strength abit.
Could poor water distribution cause this? As im just using feeder rings.

I'd just feed more if your EC is running off lower than in. Would recommend a flush mid grow if you have the issues I was seeing in my past grow (inbound 6.2ph and 1200EC, outbound of 4.5ph and 4500EC). I chalked my issue up to not watering with sufficient runoff.

EC coming out lower than what you put in is very rare for coco, my guess is poor feed distribution. If your plants are burning or showing decencies even though your EC runoff is lower than what you put in its likely the salts are accumulating in one area because the coco isnt being saturated evenly.

I'll try and hand water the entire medium tonight an see if the run off is any different, if it's accumulating somewhere I should see a spike in the run off.

Hopefully the plants are eating the nutes, to cause the low runoff ec.

How often are you feeding them the 1.9ec?
More than once a day?
How often feed until runoff?
Oh, and pot size?
Using ph range of 5.8 thru 6.2?

Feeding has been once a day, just started doing it twice a day about 3 or 4 days ago trying to help correct the low run off.
Run off is every time.
28 litre pots but there a grate in the bottom of the pots so probaly minus 3 litres.
Ph has always been between 5.6 - 6. Mind you my runoff ph is more like 6.5 but most sources I read say ignore ph run off.

I thought it was mag but after some research it might be iron as it is starting on the newer growth working down the plant, the bottom leaves seem fine.

Growth has slowed drastically since I noticed too.
I'm thinking it's close to time to flip but I want to sort this out before I do.
