Newbie what to awod this

Ppm 650 in 1100 kit
Ph6.5 in 8.2out

Iam on flush right now but have put 50L in a 15L pot but now down in 7.3 ph looking for 6.5.

Maby not inoff runoff when watering but what is the leaf tell you Masters?

Possibly nute burn. What are your feeding practices?

Now p and k only

What kind of soil and what were you feeding prior to the PK only? For ph out you need to do a soil slurry test. You can google how to do one, that is the best indication of what the soil ph is… I find the ph out of the water can be higher than the soil so I’d start there - I’m a newbie as well, so I’m going to tag a few experts here:

Looks like a lot of nutrient burn, I would retain nitrogen until a little farther into flowering. It’s starting to show nitrogen deficiency.
I would flush and reset, then start feeding again.

Yeep just flush here whid 6.0 and ppm170 of p,k.

Have 3 girls more and they not look like shit feed same and one of they is blue chees and find lithle yellow but turn more green after put Epson in water.
