Hempy bucket ph drop in flower!!!!!!!again

Here are a few shots of how my buckets are set up. I've changed from the drip rings to FloraFlex drip caps to eliminate erosion. The streams from the drip rings were too strong

well, let's check out your nutes: you said AN ph perfect sensi coco bloom a&b , correct? and just cal/mg as your additive?

Yes that’s correct

wanna try a different nute? are you close to a grow shop? or have amazon prime or quick shipping?

oh yeah, are these autos or regulars?

Photos also last time I was using canna Coco Turk ANB and I ran into the same problem at the same point in time so I’m wondering maybe it’s just a strain that has weak genetics and is super prone to root issues who knows next time maybe I’ll try GH trio I will see this and veg Sensi Grow is amazing

some strains can be finicky with nutes. my last one was a bitch with Calcium. never had to add Ca in many years since I started using well water.

with the sensi bloom you are using, aren't you not supposed to adjust pH? and you are adding cal/mg first right??

Figured I'd come over here instead of talking on the hempy thread. Here's the feed chart I use if you want it. I use everthing but the boost and calmag ro water to 150-200ppm. Have tried veg bloom, jacks, megacrop ect and keep coming back to this. Never have to worry about burn and sometimes I never water to runoff or flush and the plants never miss a beat.

I use Coco perlite Hempys. I normally have the opposite problem in flower. I don’t pay much mind to coco ph runoff but it does seem to rise a bit when comparing results week to week. Will salt buildup cause the rise in ph? Also, may it be under feeding?
As far as the problem I’m seeing here, I would switch to hydro nutes. You’re using coco specific nutes but not using coco. What you may want to do for now, mix your tap and RO water down to about 80 ppm. Add your Sensi Bloom until total is 580. Leave out the added calmag. My rap water comes out at 70 ppm. I feed my plants this way once every few days. They seek to like it.

After doing a considerable amount of reading recently, it appears that the issue is the coco not the nutes. It seems that perlite is truly inert and doesn't seem to have noticeable effect on the solutions that p[ass through it ... so much so that it is successful for drain to recovery dutch buckets that would be a total nightmare with coco.
I'm planning on switching from coco when I rebuild later this year
