Beginning nite burn?

[SupremeGroveOfGreen]

Hey, I asked a few days ago about discoloration in the leaves but I was told it’s nothing. The small light green discoloration is probably nothing, but on this new lead I noticed light green on the edges which looks a bit like nute burn. I checked my ppm and it had gone up from 470 to 490, so I diluted the Rez down to about 290.

I know the smaller green patches are probably nothing but is the green on the edges the beginning of nute burn?

actually looks like the opposite. your ppm is too low. get it up to 750-800.

I agree. No burnt tips. She just needs more food.

Thanks so much! Any idea why the ppm kept going up though? Everywhere I’ve read people say “listen to your plant, each plant needs a different amount of feed. If ppm keeps going up it’s up taking water faster than nutrients and you need to dilute the solution”
Maybe my TDS meter is just a little messed up or something? In a previous grow the ppm almost always went down throughout the week

calibrate the meter if possible.
