I am running a hydro setup ebb and flow.

Had to leave town for a week and had someone watch my stuff.things came up and he couldn't. Got back into town. Plants are showing signs of light nute burn and some of the leaves have small holes in them.

Ppm was at 2500
Ph was at 4.4

Flushed the res and ppm at 900 and ph 6.1 like usual. How bad will this set me back? Plants are 5 week in flower.

How much lower on the ppm?

900ppm right now should be fine...the ph was so low because of all the nutrients in the solution...I'd get your ph down to 5.8 though...its ok to let it drift from 5.6-6.0 to grab the most out of it as thats the complete range nutrients are available to a plant in hydro :)

Should I flush the res with ph water for a few days then give her light nutes?
