so much help on this forum kinda feel stupid wasting my time taking all those pics and posting some many times.

Whats a good ppm range to never really go over. A good starting point for seedlings and peak bloom. I am asking where I should start as far as ppm and whats too high for most autos I know they are all different?Never over 600ppm...? Why? I think those gorls are hungry as hell!
Starts down low, I would treat for under feeding. Not underwatering.
@saneiegocali92 has a great point about it looking like root death.
I'm going to re read this thread. Brb
ok my temps can get kinda high sometimes around 87f for a few hours here and there untill I see it and cool them down. so I know that plays a part in feeding. hanks so much man for helping me.500-600 ppm for seedlings
900-1200 veg or bloom
And if they can take it...
1200-1500 ppm bloom. Yes I have gone that high before. 1600 is my usual.
I feed heavy and back off when the plants say so.
