Plants stopped eating, everything in check

I’m in a 30g rdwc and my plants seem to have stopped feeding. Water levels still dropping about 10g a day. Veg I was at 750ppm (500 scale) and dropping 10-20ppm a day, but once I hit early flower my ppm started to rise 10ppm a day. I’m now sitting around 500ppm and still having a slight increase everyday. PH steady dropping as well where in veg it was rising. I checked each sites roots and don’t see/smell any issues.

Around week 6 of flower
feeding Megacrop with RO water and great white
Led lights with 1000ppfd at the tops
1350-1450ppm co2
83-86f and 57-65%RH
Res water temp 64-65f

how look the plants

The plants all look fine I’ll take some pics later but they don’t show any issues beside a cal def that was from a previous ph issue. I haven’t been around enough to be able to tell if they’ve stalled or not since this is my first run with this strain. Maybe a little behind on the bud stacking/weight if anything

I'm not an expert but maybe you should try adding some extra PK as I heard Megacrop is a little N heavy to use all the way through flower by itself so maybe it's the mix? I think they do bud explosion?

Right I have bud explosion but it’s not really necessary. I’ve taken plants through harvest with MC only. I’d assume if they were hungry for more P/K then my ppms would still drop slightly right?
 
try a 24hr flush with plain water. then start them back at maybe 300 ppm and see what happens. that usually breaks a hunger strike.

Your probably right, I've never used MC so was just throwing it out there :bigjoint:

Alright never done that before I’ll give it a go. Would dropping ppm to around 100 suffice? Just refilled all my house jugs so gonna have to wait for another full tank if I wanna do a complete res change.

one of the first and best things i learned about hydro was if you see/have a problem, give them a 24hr flush and then start back with much lighter nutes. it works every time.

you positive you don't have any root rot? that would cause your same issue

Nice thanks I’ve never read that anywhere before. That was my first guess but since they’re scrogged up I can’t fully lift them up the inspect roots, I can see half the root mass tho, then peek on the other side to see the other half. But definitely no smell, I’ve never had root rot but I have a good idea what it looks like
