How big is that pot?
@blackthumbbetty 5 gallons
Was the pic taken just before either lights on or off?
I’m noticing some discoloration on a few leaves, too.
Tell us everything you can about your grow, such as medium, nutes, pH, lights being used and their power/height, your temps and rh, watering practices, and strain.
Appears to be underlit too
I need to get a ph tester I have a 150w sunsystem
Using ffof soil , I usually water once a week with a gallon of water with a little less than the amounts of nutrients then it should with the fox farm nutrients
Yes, you need to get a pH meter.
Plus discontinue nutrients at this point. Later; yes. Not now in FFOF.
With Fox Farms, an ec/tds meter would be helpful, too. Not necessary, but it’ll help you know how much stuff is in the soil, which let’s you know how much your plants are eating & how much more food you need to put in.
