My Plant looks Healty but My Bottom Leaves Drop

Hopefully I'm doin this right and I'm in the tight place to get an answer? I have 6 plants? They all look pretty healthy but one stands out passed the rest.....it's about an inch and a half taller than the rest and thicker! But the bottom sets of three leaf sets are droopin down..... I had flourecents down by the stems on the pots..? Is that why? Plus the set above those, the tips are curlin... Is this nute stress? Just wonderin? Please let me know anyone thanks!

give us pics , descriptions arent reallly enuff to give info on buddy but what i will say is that bottom leaves regularly yellow and fall off, its just natures way of gettin rid of useless vegetation.itll happen all thw ay thru ur grow, more so at the end of flowering. nuthin to worry about as long as it doesnt spread too far too fast. thers no exact science to it more experience and practice.
