lock out? N def? Calmag?

day 27 flower
fox farms ocean soil
nuke heads flower nutes
ph 6.4-6.5
started on day 22 of flower. worsening. I have given a dose of cal mag and no changes so far. maybe nute lockout?

KebinLub is that your Runoff ? 6.5 If not check the Runoff I just water till it comes out the bottom holes and then test that.
And if that's the case I suggest you flush them out with about 3 to 4 times the amount of water to your pot size, Say your pot is 5 gallon you would need 15 to 20 gallons of water to flush properly. Then what i would do is give half the nutes you usually give, You can work your way back to a normal feeding then. I am pretty sure ffof is hot off the get go so IMO.
Give them about a week they should perk back up.

Good luck and Happy Grow. Peace out

If you have to flush add some yucca

Hi KL,
Indeed a flush is needed. Toxic ph from nutrient salt accumulation. On first post, second shot down there is clear cut Mg deficiency (note the chevron looking leaves)

So once watering is resumed...include some MgSO4 (epsom salts) or calmag depending on how hard your water is.

I have some fox Farms sledgehammer for flushing. Should I use that? Or just flush with reg ph water

Hi KL,
I wouldn't use the Sledgehammer since you are going to turn around and continue growing. Some of that stuff might linger which would be at cross purpose to your grow.

Some folks feel that a mild nute solution is better for the plant osmotically. Less trauma to roots. Maybe some epsom salts would be a cool flush additive since plant is already deficient. So 1/4 strength nutes or maybe 1/2 tsp epsom salts per gallon. One or the other. I'd choose the epsom salts if you have them. Any drug store but don't get scented.

Thanks for your help fellas

Your welcome sorry i wasn't around, but just plain tap water will do just fine, But johnDee idea is right on the money.
Good luck Peace out

Another reason to use a mild nute solution...........salts grab onto salts.

Definitely a mag deficiency. And looks like your pH has been a little erratic as well. If it's a salt build up your runoff pH will be acidic and ppms will be high
