Lower Fan Leaves Slowly Drying Up

so my girl is almost 5 weeks into veg. its 36 inches wide and 16 inches tall. the plant is super healthy looking except for the lower fan leaves. they have slowly been drying up and d dying. ive only lost about 7 since about 2 weeks on. is this normal? the lighting is decently good but because the plant is so bushy, the lower section of the plant doesn't get alot of light. could this be causing it? also its in a hydroponics setup. thanks in advance.

Yep just let it fall off. Make sure you pick the leaves out of the soil because they lower your PH!

alright thanks

leaves in soil lower ph? wtf?
