We want to stack the EC throughout the grow and you want the roots to be in optimal state to take up nutrients again.Well for starters you constantly use technical terms in the wrong context. You write that drybacks which only causes heavy EC rise and pH swings somehow is a positive marker since it "stresses the hell out of the plant"? The only result is stunted growth because optimal requirements for growth are not being met.
The plant doesn't in any way become lazy when optimal requirements are being met. Something you stated in earlier post, total nonsense. The roots die off with drybacks it doesn't cause "explosive root growth", again total nonsense.
The root network expands because it is trying to get to the little water left in the coco and therefore the plant grows rapidly.
Dryback in coco is max to 25% vwc
And saturation is at 50-55% vwc
So I think I got my terms right...
Don't dry out the coco, dry backs are the way to go.
Accompanied with proper flushes during the right stages of growth there won't be much of an EC rising.
Really look into p1 p2 p3 when growing hydroponics.
Basically like I tried to explain before
Your lights go on and the moisture content has gradually been going down in the coco
(So from lights-on until your first fertigation is phase 0.)
U can steer your dryback to the desired level by postponing your first fertigation.
Now starts phase 1,
You add shots of 1% of your VWC to your coco or rockwool.
In between each shot of water u wait about 30-45 seconds to prevent undesired run off.
This all allows the coco to slowly resaturate as this takes more than 30 mins.
Now you've reached your field capacity ( wastei that means the maximum amount if water your coco can hold )
So phase 2 begins
Phase 2 u have small drybacks throughout the day and maintenance shots to stay at field capacity...
Key is knowing when to stop the last fertigation to reach the proper level of dryback next morning.. this is called phase 3.
I hope you understand better now
