plant bottom leaves dying

heading into the 2nd week of flowering and all bottom leaves are starting to die is this a problem and how can i help fix this problem if so everything else looks healthy

no a lot of growers trim the lower leaves off called lollipop trimming.
you want to remove the dead ones and trim a bit in the least.

...Mind you... if you have a small grow and have sufficient light all around you want to remove the least possible..
So depends and I responded without knowing what your exact grow conditions are

no its not that small i got 13 plants bout to add another light in there real soon tho so that may fix the problem right now got a 600 w hps did the trick for veg but i dont think it will cut it for flowering alone pe's are 3ft nls are 2 sumthin so yea bout to add a t5 in that bitch as well

how big is your grow area? 600 is good for 3' x3'

between week 4 and 5 I really cleaned out a lot of upper fan leaves to open up the lighting to the lower branches. I also increased nutes that would add to bud locations and had/ have an explosion of buds
Now my girls are starting to look more like corn stalks then bushy weed..
I have 6 in a 4X4X8 and the 1000 w hps cool tube does the job and then some

my tent is 4x4x6.5 some1 recommended a 600hps but obviously that isnt enough so i will just throw a t5 in there real soon
