Toxic Salt build up! Solution?

Hi there :)

Setup:

Grow tent 1,5m2
600w HPS
Light Mix Soil
GHE Flora Serie
15L pots

Week 6 Flower
Strains; Skywalker x1, Himalayan Kush x1, Unknown x7
(some bag seeds i got from a friend)


Ive resently had some problems with 3 of my galls. I belive its toxic salt build up.
This started about 8-9 days ago, I started to flush when i saw it, have flushed them 3 times, each time with temped and Ph'd water. Aprox 20-40L each.

I belive the reason fo this salt build up is because I havent given them enough water, basicly no run off. I have changed that now.
Ill also have to add that the water is using LONG time to get down and thru the pots, think the root ball is huge.

Anyway, the 3 affected plants seems to continue with the signs for salt build up.

Does anyone have any ideas to fix this before the plants die on me?

Are you getting the bud formation you'd like to see? At 6 weeks flower they're just about done. I'd say transplant to bigger pots and go easy on the ferts from now on, but they've been in flower to long I'm not sure it would be worth it. What you can do is learn from this and take it easy next time. There are different ways to fert plants which takes all the guess work out and just lets nature do it's thing. You mix some powder fert in your soil and just give water as they grow. You won't have any more nutrition problems in the future. You live in Oman?

The plant won't fix the damage already caused but you shouldn't notice any new damage if you flushed well enough, it probably wouldn't hurt to flush it a few more times. As long as you have good drainage it shouldn't be a problem flushing again.
