Cant figure out this problem (pH or nute def?)

This has been happening my past 4 grows and its starting to really bother me because i cant figure out the problem. Heres some pics of my newest vitim Dark Devil Auto.






And now again with my new Jack Herer.






It seems like its happening earlier and earlier in the grow now. Before it was after flowering, now its starting as seedlings.



I use fox farm happy frog w/ perlite. Fox farm trio following schedule at 1/4 strength and cal mag. For the dark devil i only fed once, and the seedling i havent fed at all.

77-90F

anyone have any advice?

I use FF.
What is your solution PH?
What is your runoff PH?

Id say PH is out of whack. I run FFOF and their trio pack for now and I have the same problem sometimes. This grow it started with spots early on, but after I flushed with PH'd water the problem didnt progress to the rest of the plant.

Id make up some PH'd water and give the newer plants a good flush the next time they are dry. You want a lot of runoff. Just collect the runoff and check it until you start getting water that is PH'd and low PPMs Then you know you're starting fresh with solid PH and low PPMs.

From there just make sure you PH your water, and be sure you are PH'ing your nutrient mix *after* you mix it together. Should stop the problem and help get your plants on track.
