high everyone,

i was wondering if it's a bad idea to have a fan blowing air over my plants constantly...i don't have an oscillating fan and i've been using a small box fan...

some of my babies tips are browning and some of the other ones leaves are wilting...i haven't started using any fert yet so it can't be from over fertilizing...it may be from a ph imbalance but i don't have an accurate ph meter yet..

any input would be helpful thanx
