Check ppm everyday, if it's rising ppm too high, I like to see around 20ppm drop per day anymore than that I will up my ppm's. In dwc I max out at 450ppm with ro water anymore I get tip burns

I agree ,
Gotta watch ppms daily,
I usually run 500 to 1000 in veg and 1000+ in flower .
You really need to make sure you have alot of air and water movement on your roots.
Lack.of air will impact your plant immensely.
I like to over kill the air, I run a large pump and 4 stones in a 27 gallon rez.

Are you running sterile or live?

How often do you change the res?

What nutrients are you using and how are you mixing them?

What is the source water ppm?

Res ppm?

Where is the waterline in relation to the net pots?

How are you doing tops ups?

Ita the start of a Potassium deficiency and there can be many causes. Potassium is very important in regulation of water uptake for the plants.

It could be as simple as ppm being to high or a nutrient imbalance. But more info is needed.
