Are these looking healthy?

ALRIGHT I AM GROWING 5 CHRONIC PLants in a hydroponic drip system/ nutrient flim. my first system and i made a few mistakes.the resovoire isnt light tight but still seems to be growing fine. this could have been ph problems because i just baught a liquid balance kit once i started to have problems. i am using 5 t5 14w about 1000 lum/each.and will be budding with 600 hps. the nutes are a real easy week to week instruction called bada bing bada bang bada bloom by holland secrets. are these plants ready to clone and put to flowering. they are about a foot or more tall. i have noticed that the root growth from the side of the pots are turning brown and dying because they are not reaching the waterand possible light issues but the bottom roots are growing fast. i will post more pics because the plant seems to be loosing the wilted edges and in the first pic the plant almost is a little purple and the tip may be turing yellow.. not to sure

looking good...yep,,you could take clones from that..just a couple
