Change In Color

So today I come home from work and check on my babys and 2 of them thier bottom leafs have turn really light green not spots but the whole leafs.
but the other 4 are fine
Im growing in soil and its preimer pro mix and im using advanced nutrients grow mirco bloom

bump
can someone please help me starting to get worried about those 2

What age are your plants mate ? When you say babys, are they young ?
Lower yellowing is normal in flowering i beleive, as the plants are using them up

More info is needed tbh if you are to get any real help m8 or a pic or two.

Gd luck.

They are like a month and a half and im just about to put them into flowering
I did take some clones off them like 5 days ago could this have something to do with it

maybe, im not a pro, but it might be usin alot of energy to heal... depend on how many clones you took at once?? i had some that the bottom leaves slowly faded until they were completely yellow because of over feedn tho. maybe check your ph
