there is like 3 things that I think could be rong with my plants eather high heat because there is no fan/ I'm growing in a cabnit. Second it can be over watering and third is underwatering. I'm growing in stiriphome cups and my plant is like streching twards the light and then the stem got vary skinny and then started falling over. My last plants did the same thing but they got to 5in before they did that and my one now is like 3in. Is there any recovery if there still green. Plzz help me find out what the problum is. And when the plants are that high is it bad to have constnt light on them or should I turn off the light for the night time?
