what hind of soil are you using? could have a lot of nutes already. as much light as possible at this point is fine, so no it was not your light.
but yeah slow down on the watering this can have the same results as over feeding in soils with a lot of nutes, like Fox farms or roots, without mixing them with amendments hav a lot of nutes and the soil as is can get a plant through about a month or 2 of growth without adding nutrients.
no you plants a lush and full of water no visible deficiencys.
