small growth and yellowish/ lime green leaves

I see a couple possible issues my friend. 1.) Nutrient Lockout 2.) Available nutrients 3.) Overwatering 4.) Light Intensity Again possibilities. Here's why; 1.) At too high of watering ph the plant won't uptake the right range of nutrients. This leads to the plants using stored energy in the lowest growth first. 2.) Some promixes only retain nutrients for up to two irrigation prior to needing supplement. If nutrients are added when they are not needed you risk toxicity issues and could really stunt growth. Some nutrient burn signs may start showing up, but I don't think that is what is completely happening here. 3.) Waterings are the hardest thing to nail because too much you risk suffocation of roots, drowning, or rot issues. Underwatering will cause almost the same signs and damage the only difference is feel. One will be way dried out obviously. Both will show signs if wilting too so pay attention to your medium and try to make sure that the mediums surface dries out between waterings. 4.) Light intensity being too high will keep your plants shorter and you could look at I as the little plants may cower away from the biggest light. Make sure to not destroy them with too much light as a young plant. They only have small leaves and can't really do too much until about mid week 2 of veg. Regardless the plants are suffering as you noticed, but they aren't a lost cause my friend. Adjust your PH you water in at, dechlorinate your water by letting it set out for 24 hours to gas out the chlorine. That alone should help a lot.
