My little clone is not growing at the same rate as the others

So my leaves are curling in and the plant has barely been growing, I watered twice in one day because I realized the first watering had an off PH so I basically flushed with the correct PHd water the second time a few hrs later, which caused my 6 clones to get overwatered and have leaves curling down. I let the soil dry out a lot this past week between waterings and there starting to recover (leaves are starting to get more straight) I don't know if that was from the overwatering or maybe me watering twice in one day caused the plants to absorb more nutrients and get a nitrogen toxicity. Anyways they all seem to be recovering okay after that but my dosido clone looks like shit leaves are still very curled in and the whole clone is turning purple( I know it's in its genetics but it doesn't look that good even the new growth is starting to turn purple.)

Here is my setup:
Soil Fox Farm Ocean Forest
Container 1 gallon smart pots
No nutrients added in yet
Clones are 13 days old
Lights T5 4' 8 bulb fixture 40000 lumens + another T5 2' 2 bulb fixture on the side 4000 lumens total 44000 lumens
Plants are 2" to 4" inches away from light
I have a small rotating fan on low speed blowing air and moving left and right.

Please help

Hi how are you doing today? The one between your legs is still wet, pic shows that clearly, overwatering will kill them out, you put them into nutrient soil so thats how they burned. Under floros it takes twice as long to dry out due to heat not being a big issue, learn to feel the weight of the pots to determine when to water/feed. I let mine dry out to the point that the leaves are laying against the stem almost - Thats dry - then water a few times to allow all the roots to get soaked well. For now I would say wait and watch, dont have any fans directly on them but provide airfow you dont want to wind burn them too. once they get some more roots they wil handle the medium choice better, hope this helped.
