Can’t figure out this problem

Yeah the closer you get to harvest is, generally speaking, the more you should cut back on nutrients...not because of flushing/leaching and all that stuff as I know that's kinda controversial, but rather because your plants really do stop feeding as intensely about half way or 2/3 of the way through flower....half way through I always cut my nutrients by at least 1/3, feeding 2/3 of their regular dose. If not I get bad yellowing/browning/burning up top of the plant and it sort of resembles a cal/mag issue, but is really just because the nutrient salt is simply too concentrated in those leaves.

PP,
There's lots of products out there. He's probably using House & Garden's Drip Clean which is a product that helps reduce soil nutrient salt build up. I think hydro guys use it too...partially for the reason you suggested.

I looked that stuff up and its to keep drip lines and spray jets clean so made for hydro use only really. I certainly don't see a need for it in soil/soilless grows.

I've never used it...but like you I decided to look it up. This is what I read:

"Salt buildup in the root zone can cause numerous difficulties, reducing plant growth and vigor by altering water uptake and causing toxicities or imbalances. Only House & Garden’s Drip Clean uses ionic bonding to safely remove excess salt molecules from the soil or growing medium, preventing salt buildup and allowing plants to thrive."

http://sdhydroponics.com/2012/01/11/using-house-gardens-drip-clean/

It sounds somewhat similar to what Flawless Finish does using chelation which is a form of ionic bonding. Only the FF is primarily for end of grow flush.

So it appears that your reading was incomplete. Originally it was marketed as hydro only.

At the start i was also using drip clean, like 0.5ml in 5L every second watering but stopped as I thought maybe it was having adverse effects

Yosim,
Since the subject of this product has come up...I think you were smart to stop using it. What I am curious about is how the stuff only selects bad salts to bind with. Maybe it did remove something useful.

that is really interesting because I have cut back on my feed and expected to see more deficiencies but plants got no worse, i will bear what you said in mind, thank you

The reason I started using this House and Garden drip clean was because I saw it somewhere recommended for Autopots system (which I run) to keep the lines clear - however about 1/3 ways into my grow one of my lines actually blocked, so my conclusion is it did SFA to prevent the problem i was actually trying to prevent! hence i just stopped using it anyway, thanks
