Heading into week 6 being fed with megacrop and sweet candy. They were looking mighty light so I upped the feed yesterday. Picture makes it look darker (healthier) imo. This out of the 5 I have going is the only one really being unhappy and started developing these spots. They are kinda drama queens, drooping like 4 hours before lights out.

better check the in-pot pH, looks like P defc. most likely,... You'll need a good soil pH probe, the Accurate 8 (CPW) is a solid choice!
Diurnal droops is a fairly common thing, so nothing to sweat there,... several of mine do this as well, but not always...

Yeah iv been thinking it time to grab one. I have a bluelab ph water pen and love it but their soil pen is far too expensive. Today I upped the feed and water at 6.3. The run off was 5.8

run-off from feed and/or even adjusted-water only is a very poor measure of actual in-pot pH.. that fact that it went down like that indicates it's definitely acidic in there, enough to force buffered soln. that low... hints that it's off pH in there!
Look in the Sticky article section above this one for the run-off test and calculation method and you'll see what I mean,... even with this, run-off is dubious for pH in most cases,... a lot can skew readings! Hard water (it's the mineral content CaCO3 that does this in tap water, and Ca-mg to a lesser degree) ...
