Can't figure it out

The set up is 27 plants in 3.8L rhizo (fabric) pots.

1 x 600w & 1 x 660w dual spectrum hid lights
1 x 1150w dual spectrum gavita pro de

All been drip fed from irrigation system

Soil is biobizz allmix

Was using biobizz fishmix (instead of their grow) with added calmag due to deficiency, switched to shogun terra and rock resinator for flower and to avoid the drippers been clogged by the organic nutes

exhale co2 bag

2 fans blowing the air around

Plants have been vegged for 3.5/4 weeks and are now 5.5 weeks into flower

This problem has appeared rapidly over 2/3 days, i foliar fed with biobizz calmag (organic) as this was the only calmag i had at the time, i have since added shogun calmag to my nute res to help solve the problem but im guessing since im in soil it'll take longer to break the nutes down ready for plants (i usually grow dwc/hydro) 1st time with soil LOL


I thought it was calmag, others said on another post that they're hungry and others said Nitrogen deficiency, so i added shogun terra GROW for some extra nitrogen, it doesn't seemed to have worked

I usually ph in hydro but haven't in soil after been told soil buffers itself, anyway i decided to check ph, ec and run off

Run off info is :
3.6EC very high
PH is 6.3/6.4
Water temps 20c


Water going in is 0.4/0.6ec (0.2/0.4 is background)
PH 6.2
Ph 6.2

Is the high EC coming out due to salt build up?

Plants haven't really got any better since i up'd the nute strength to 2.0ec

Started to flush for the next 2/3 feeds to try flush out salt.


Any ideas?
Am i right or wrong?
I'm at a loss right now aaaah

Lockout. You're feeding plants in fertilized medium. Options are plain water only for a while or flushing. I'll venture a guess that calcium is the major cause.

Thankyou, i did have a feeling it was lockout, how long should i water with plain water for?
