Flushing don't seem to solve my lockout

Hey bro. You have been running your ph at the high end for flowering for coco. This stops a lot of the nitrogen uptake which really looks like what has happened to me. Highest ph in soiless that I go is 6.2 to start when flowers have formed. Full flowering imgo to 6.3. At 6.5 very little nitrogen uptake happening at the root zone. Cheers

Bad timing mate.You should be ok by now.It looks like its on the newer leaves and not the older one's.I wouldn't bother with any more Bud Candy,its about due to stop anyway and I'd cut that Overdrive down by half.1ml -1ltr.Iv used Advanced 2 part Coco,for a few yrs now,used the 3 part before that and just going back to soil and Iguana Juice with Candy,ignight,big and over.Get some Microbes and Fungi next time.I sue Voodoo Juice and make tea every few weeks with voodoo,charge,bat shit and molases.It should help with issues like this.Hope it hasn't got any worse.You should of got some Revive when you got you Cal-Mag.Get some Amino Acid if poss.Amino Treatment from house and garden or Raw's Amino Acid and some Kelp.Ups your Calcium intake from between 300-1000 times.

Usually after a hard flush you've just removed most of the Nutrients. I'd have fed them not long after the flush. 🤘😤

If ur gonna flush from a lock out better use at least ⅓ of the pot's volume in water. So around 3.3 liters for a 10l pot. This how i do it. But its up to you. Stay lit growmie.

I have faced this lockout once. All I do is flush till ppm in runoff is low and start to feed nute in a little and add more next time.

I've never had lockout but I do know fixing an issue won't happen over night. I would trim those bad leafs off and give it a feeding if needed and watch and see how she reacts. Hopefully she'll respond well to the flush you gave and never skip a beat growing.
