Any ideas??

I just started noticing this today. I did change the RES two days ago. She’s a little over 4 weeks old and is cheese autoflower.

PPM: 335
PH: 5.7
Temp 68-79
RH 39-50%

is this something to be concerned about? Or just keep rolling?

Thank you!
RF

335 PPM sounds low for that size of plant or are you adding 335 PPM of nutrients to tap water? Looks like a magnesium deficiency.

Well two days ago when I did the RES change the PPM was 450. But then I added about 1.5 liters today because the water was low.. then I checked the PPM and it was 335 now. And yep, tap water PH’d to 5.7

I am chasing a similar look with the burned tip, I'm between wind/Light burn or needing more cal mag nute. Following

I feel like all those things look the same on a leaf lol I’m thinking it’s either light or mag issue. I use tap water, floragro, floramicro and florabloom. And running around 350-450 PPM idk how it could be nute burn..

Why would you add plain water to a res of already mixed nutrients? Of course adding water will lower you PPM from 450 to 335... Keep your feeds consistent.

You didn't state what medium but with that pH I'm assuming coco.

And I didn’t think I was suppose to add nutrients other than when I changed my res?
Sorry I'm stoned apparently. You said res, and my brain thought reservoir for like an auto feeding system. I'm hard wired DTW apparently. I don't know hydro, have a good day. Carry on.

I would up your ppms, try 600?, and aim for a range you are happy with. I end up topping my res up with nutes every 5-7 days.

i am doing DWC and need to add about a gallon on nute water each day to each plant.

I am using cultured solutions nutes

No just water, I always bring the ppm to the week of the schedule I'm on.
I bought 4 extra buckets and fill them the night before a week change.
I'll transfer the girls with the air stone into a clean new bucket.
