Newbie (but of course!) Nirvana NL autoflower, oldest are 5 weeks, Mars 1200 LED, supplemental T5, 48*48*80" tent, ph always adjusted to 6.5, temps been very good at 75-79 degrees , humidity is running low since adding Phat 6" vent can/fan etc, down as low at 16% but more so around 20%, fan on slowest speed by my variable controller (I also have a cold air humidifier and a wet shamwow sitting in a tray to try to increase humidity) I am running lights on a 20/4 schedule, during the 4 hour lights out, the vent fan is also off and then humidity can run up to 55%, temp goes down to 70 or so (supplemental small temp. controlled heater) Using FF nutes, and supplemental GH Cal Mag, and Silica.. Just started a bit of Molasses. I did find a few bugs but sprayed with Spinosad, and Neem. Laid some diatomaceous earth on the top of the soil on the two oldest affected plants, yellow sticky card seems to have found only 1 flying tiny bug... so I don't think that is a real problem? In 3 gallon air pots and I'm now watering them from the bottom. I'm having a hard time getting the watering down, too wet, too dry!? Roots are coming out of the bottom of the air pots. Soil is FFOF~40%, Happy Frog~30%, extra Perlite and Coco round out.
I know this looks like Nitrogen deficiency???? I only see it on the fan leaves and it seems to be mobile but I have fed them a pretty potent nitrogen dose at least a few days ago, EC was around 2.5+ or so... ? WTH? HELP! I tried to get a better pic of one of the yellowing leaves and DID notice (again) some tiny black spots so I tried (!) to get a pic close-up (I have an iphone close up lens coming soon) through my 45X loupe... if that helps? That very white on a side leave is definitely diatomaceous earth, and might be the white you see in the close up?
