You should try and maintain a relative constant water level, because as the level drops the PPMs and salt concentration rise. not good. Ph will also change

I know a lot of plants can go a while without water, but its a stressor, sometimes a good thing but usually NOT

put them on Ph corrected water for a few days, then go back to nuits. see if those top leaves straighten out , if not no worry.

Daddynobucks Reviewed by Daddynobucks on . Two important questions, 21 days flowering Im on my 21st day flowering, three females left, one small 12 inch plant and two 3-foot size plants. My first question is about picture #1, towards the very top of my plant the leafs are curling around the edges, but no where else on the plant and the other plants aren't doing it. Is this just part of the flowering process? Maybe lack of light to that part of the plant cause that one out grew my lights?? The second question is how long can this aeroponics system go without water?? The Rating: 5
