Hello all!
The plant is a Vision Seeds Amnesia Haze auto in a 15L airpot with potting soil, fed 2.5ml/l each of Biobizz Grow, Bloom and Topmax, getting about a liter of tap water that (almost always) sat for 24 hours per day. Spends half of the time under an unreflected setup totaling 40W CFL desk lamps, and the other half under nice full sun.
I'm not sure about it's age (about 2 months maybe?), but it's more than a month into flowering. The trichomes don't seem to signal harvest time yet.
It has taken some burning one day when it was too hot outside, some leaves burned and fell later, growth slowed for a few days, but nothing lethal.
Haven't had a single problem until the last few days, where it seems Nitrogen is defficient. The lower leaves are yellowing uniformly, as can be seen in the pic. This just sounds weird to me since the nute dose seems right, and I am afraid to up the Grow additive, in the event N is not defficient.
I should add that some leaves (healthy ones too) have their very tip browned out but this has been like this most of the time (same as in my previous real outdoor grow, which showed no signs of deficiency all the way) and doesn't seem related to the problem.
I'm only able to upload this one pic at the time but will add more in a couple of days.
Thanks a lot for any advice!

... if you're going to take her in the next week or so, then just stay your course,... longer, give one last stronger dose, and let her cruise over the finish line..! Since you're using organic, mild stuff, no need for a lengthy cleanse period; give her nothing but water, lightly, the last few days before harvest,...
She's fattened up well, is full of resins, and in a week, she'll be good and ripe! Have you looked at the trich's to assess color and appearance? I bet she's near to all cloudy now... cloudy = ripe trich's! Amber comes when the THC starts to degrade into CBN, the narco-sleepy cannabinoid,... How much is a personal choice as to buzz preference,... as an Amnesia Haze cross (Sativa dominant), she's likely to have a very up, energetic happy high...
... cheers Hey! have a nice fat Rep' 
for starters!
