Please help if you can. Started about a week ago. They are 5 gallon pots on a concrete floor, could that cause issues? Grow 220 led lights 2 feet away approx.
Looking at your pictures the leaves seem a little pale, maybe nitrogen deficiency? Perhaps post some details about your grow to give people a little more to go on.
Is this hydro, soil or soiless? What are you feeding them? What is the PH of your grow media and your nutrient solution if you use nutrients?
I don't think that's your problem but not a good idea to rest the pots on a concrete floor. Get some pot stands. I use them on my 5 gallon fabric pots. These are the ones I use.
Amazon is a tad expensive for these, I got mine at a local hydro shop much cheaper.
