New grower having problems with white bottom leaves?

I'm new to the forums, but I plan on utilizing this research much more. The bottom leaves on my one of my two indoor plants are turning white. I just repotted them recently and just started them on grow nutrients. I don't remember how old they are, but I'm going to guess around a month and a half to two months. I will say that I didn't have proper lighting at first but now I have one 45 watt red and blue LED grow light that seemed to boost their growing speed. Any idea what could be turning these leaves white?

Also if it helps, the nutrients I'm using are FloraNova 7-4-10. I'm using a little less than a tsp per half gal. Also upon further inspection the second plant has a similar problem but not any where near as bad.

Nothing to worry about. Those are older, early fan leaves that the plant doesn't need anymore and likely sucked the nutrients from but now that it's in a new home it looks like it's doing fine.

If it were a nutrient deficiency it would be happening to other fan leaves but it's not spreading. Those old lower fans that are at the base of branches tend to fade away and can/should be removed when they get ugly. Helps with air flow too with bushy plants and won't be missed by the plant one little bit.

Plants are looking really good and show nice healthy top growth with strong stems so I's say they are doing fine.

Thanks a lot. I've just been freaking out a bit about those leaves.

No problem. A few more grows under your belt and you'll be a lot more relaxed about little things and get to know more what's a problem or not.

A lot of people are into defoliating their plants for higher yields and strip off lots of healthy leaves. Let your plants dry right up 'til they are drooping really bad and the weakest leaves will die off on their own. I "accidentally" do that every so often and my plants are doing fine.
