Hey, I am a novice but are the bottom sets of leaves on your plant yellowing from the pictures it appears so. Is that why you thought the temp was bad? Most likely Yellowing bottom leaves means low nitrogen levels in your soil. If you add some thru good nutes it should help It also slows growth (wich you dont look like you have a problem with) also look for purple in your stems also an indicator. Hope I'm not overstepping my bounds just have just had the problem before and thought you might like the info.:jointsmile:
