Okay, so it's been a while...

like more than a year - what can i say? i've been busy - eating...and cooking...and growing (or trying to grow) vegetables in humongous clay pots on the deck...something is causing the lower leaves one of the cherry tomato plants to yellow - early blight? and its upper leaves are tinted purple - low phosphorus? just noticed this yesterday - there a zillion baby tomatoes on this plant, and i don't want to lose it...
