one of my plants looks good, the other has some sort of problem. if anything, i've underwatered it, but i think i'm watering it on time. i've given it grow big 3 times. 1/8th tsp, 1/4 and 1/2 per half gallon (then that is split between the 2 plants), so i don't think i've over nuted it (no nutes in soil) the tips of the older leaves (big ones) turn yellow then dark brown. some browning on the edge of those leaves. they are pointed up, and a couple leaves are almost twisted weirdly. i can get some pix if needed. they need water now, so i need to figure out what to give them (no feeding scheduled for today otherwise) edit: they're in soil, ph of runoff has been between 6.5 and 7 since i started.
