m0useanswered grow question 3 years ago Is your diaries information correct?
2500-PPM and EC-5 is cray high. I'm am surprised they are alive if that is correct reading.
You may need to calibrate your TDS pen and confirm the numbers are true.
If they are real, you need to lower the feed immediately and flush it out.
If the numbers are not correct you maybe underfeeding your plants. you can use 1/2 of the feeding schedule recommended by AN but keep calmg normal. Auto's are not as heavy feeders and like less.
your lighting also says its 17/7, 18/6 or 24/0 is the ideal settings. I prefer 18/6 myself for autos.
Best Of Luck and Happy Growing!
