Second week of flowering, and my very own lettuce plants are finally starting to gain some (sort of) height. I might fuck'd up a little with LST on one of the ladies: the main cola is stretching, leaving the other ones below. On the other plant, all the colas are growing at the same height, forming a nice, even canopy.
I've started to increase their meals, slowly giving some more water and nutrients, keeping on the lowest side of the suggested doses. Some of the older leaves started to yellowing, so I've cutted them (but I don't think to call that a defoliage). Lowered a little the light, they seem to appreciate their environment. Temperatures are rising, sun is shining. Maybe I'll start to show them some natural light outside the box, in the future.
