This picture pretty much sums up my problem of the day, weak stretchy stems coming out of top right after flipping to flower and they are purple. Also you can see the tips of a few leaves browning and dying off in the area...I found some more purple stems on my other plants as well even some main stems have purple hues, what is my problem here? All i can think of is temp drops and night and maybe the leaf burn from me moving the light a tiny bit closer for flowering? However the two don't seem to make sense together really. i've put a heater in the room to keep temps 70-80 and I have a good fan in there and it's obviously pretty cool so I dont see why my leaf tips are burning...I'm confused. Any help will be great appreciated and +repped. Thank you.
