Sick plants

[cman]

Any idea on what the issue could be for these? I suspect it's nutrient related since I just changed the water in the hydroponic setup but unsure. They are only 2 1/2 week old plants

Worst way to start 4/20 weekend

Looks like heat or humidity stress.

I wonder if the reflective film on your pails could be causing hot spots on your leaves?

It got too cold in your room homie. Your hygrometer says the low temp the past 36 hours was 64 degrees. I had that same issue on 1 plant that had an ac unit blowing directly on it my first grow

And I'm pretty sure the high says 86 degrees. Get your temp in check. Look on amazon for a thermostat controller that you can plug an ac unit into. I have 1 that can set different night and day temps for maybe 40 bucks

Thanks for all the tips n help. I hopefully got the temp in control and added a little humidifier in there. Plants seem to still be growing and looking healthier
