red branches need help

so i have been noticing for about the past week or two that the branches are startin to dramitcly turn red on me when i went to shut the light off yesterday i noticed the all the branches off the main stem are all red so i have been tryin to flush the plant out with just plain water no nutes ant suggestions would be great thanks for ur help later

mine are purple i didnt know they werent suppose to be

most of the time thats just how some grow. mine grew green then change to purp. and red but there was no problems in the growth, well... none that i could notice

Its usually a sign of a deficiency. Could be due to nute lock caused from inbalanced ph.

I agree with punk.

What soil are you using, and are you flowering yet? Maybe a P deficiency?

i had red streaks in stems when ph was low_ correcting ph helped
