A lot of the time people think they have a stunted plant when the actual cause is something else. The most common mistake is putting brand new seedlings straight into large pots when they first go into dirt. Plants will not hardly grow above ground (apparently stunted) until the root mass has grown out to meet the side of the pot. The first couple weeks in dirt are spent growing that rootball to support the plant. By going straight into a finishing-pot size container the plant will just grow roots for weeks. That is why we transplant a time or two 2 while vegging. I typically put new seedlings into solo cups for a couple weeks. Then they go into 7-inch square berry pots (about 3/4 gallon) for another 2 weeks. By using small containers early we are speeding up the time the plant needs to grow a supportive root mass because the distances from plant to inside pot surface is quite a bit less.
I'm not saying you didn't stunt them with nutes, just saying it's a good idea to check the other obvious possibilities too.
Good luck, BigSteve.
