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

Ok guys I really need help I’m freaking out last run with this strain I ran into the same issue at the same stage of flower week 4 hits the ph runn off drops below 5.3 and I started seeing burnt tips my ppms leading into flower where 500 week 4 I’m at 600 it was fine for a few days then boom ppm run off went up hire than influx and ph in was 5.8 untill now it raised to 6.3 by next morning now suddenly its dropping to 5.3 by next morning and they stopped feeding ppm run off is higher every day I check it and add new water after draining could it be because the stretch stopped now they don’t need 600ppms? So I’m over feeding and that’s why I’m seeing burnt tips?help guys I really don’t wanna botch another harvest....ps threw repurchase this strain ilgm black widow is a light feeder

are you feeding every watering? from the little info given, u may have a salt buildup in the medium... flush with phd water a few times and then resume

I did that 2 days in a row I’m growing in Hempy buckets so I have to feed with every watering just checked my Rex ph in bottom of Hempy buckets in 1hr it dropped to 5.5 from 5.9 wtf

thats not necessarily true.... flush until your ph stabilizes then put them on a feed feed water schedule....

if you can you add more information to the nutes ur using, temp, whether ur doing a 100% perlite hempy or a coco hempy etc

feed them twice a day during lights on at 300ppm. don't worry about runoff pH.

we dont know his medium or the type of hempy hes doing to recommend that.

doesn't matter what medium.

Unhealthy roots can cause the pH to crash. A large population of bacteria (either good or bad) can cause the pH to crash due to the organic acidic excretions. The small reservoir capacity aggravates these issues greatly.

there is no reason to feed (if using perlite with a res) twice a day...

What is that red cup in middle of pot ?
What medium are you running for Hempy ?

100%perlite lower ppm to 500 im in week 4 flower with cal mag I’m at 250 with ro water 50ppm doesn’t seem like enough food to finish flowering

As far as Bacteria goes my last grow in coco did the same thing at week 4 flower with low ph so I don’t think it’s that

That red cup is my empty protein container ins clear I have the black pot to block light

Also ph run off shouldn’t mater but I see issues every time it drops. So it’s a indication somethings wrong the runoff ph never dropped like this and everything was fine untill it dropped now I’m seeing burnt tips from lockout

also lockout dont give u burnt tips over feeding does

I have a 55gak bucket so their sitting in that for 1 week then I rinse it out and Chang it

I’m looking at some pics of deficiencies and it’s hard to tell because I’m still new to this I lowered ppms to480 lights go off in 2hrs I’ll give an update tonight when light turn on again thank you guys for the insight and making my thumb get a little greener

Too much K can acidity the rootzone. What ratio is your bloom nutes?
