Hello and welcome to the forum.
Your plants are way under potted. They need to be in great big pots as soon as you can. Minimum 5 gallon. 15 gallon would be better.
Water them in with something like Pro-Mix 5-15 5.
If you are growing them in soil. Mix 1/2 cup of bone meal into the soil of each pot before transplanting.
Fill the pot up to 1/2 inch from the top pressed down a bit. Spread the bone meal on the top and rake it in 1 -2 inches deep.
Transplant into the pots. and water well with 5-15-5 to get the roots going. They should green up a bit as well.
If growing in soil, I'd suggest you also add mineral solution. 1 Gallon jug wood ash to a 5 gallon bucket of water.
Add 2 cups of solution to a gallon of water once a week along with Cal Mag and Fertilizer.
The way the leaves are canoeing is caused but light stress. Light is to hot or to close to the plants!
These plants are a very light green. This is hunger for nitrogen. The 5 15-5 will get the roots going and give them a little Nitrogen. A week after transplanting deep water with 1/2 strength once a week with Promix 12-6-6 for 30 days. Then full strength once a week.

It's a good all around fertilizer for Veg.
The spots on the leaves are Calcium deficiency. After Transplanting Water them in with some calcium along with the 5-15-5. Don't over do it. Just a little as the Bone Meal will soon be providing most of the calcium your plant requires. If you happen to have a little Cal-Mag you need to give them a little. 1/2 TSP pr gallon once a week for rest of the grow. So Mix 1/2 TSP of Cal Mag in a 1 gallon of water. Add 2 ozs 5-15 -5 to gallon water and deep water ASAP. This will get them going.
Next Week: Begin with 1/2 TSP of Cal- Mag in a gallon of Water. Add 1/2 TSP 12-6-6 once a week for 4 weeks.
Week 5 mix 1/2 TSP Cal-Mag in 1 Gallon of Water and add 1 TSP 12-6-6 once a week until you see buds forming about the 3rd week of July.
Then switch to 1/2 tsp Cal-Mag in a watering can of water. Add 1/4 Cup 5-15-5 per watering can once a week. The rest of the time just water when needed..
This will also work in potting soil. But you need to watch the PH of your water so you don't have lockout problems. Use Rain water if you can.
If you are using potting mix. Don't use the Bone Meal as described. Up the Cal=Mag after budding starts to 1 TSP pr gallon mix in your fertilize.
This should fix you right up.
