Does anyone know why my leaves are yellow

WELL MOST OF THE OLDER LEAVES ARE TURNING YELLOW BUT THE NEW SETS
ARE NICE AND GREEN SHOULD I KEEP TRIMMING OFF THE OLD ONES
OR WHAT SHOULD I DO

no don't trim. looks like you need nitrogen

mix some pee with water. pee has nitrogen in it

dont do the pee thing
just use some extra veg nutes
try incressing you feed
if your doing 1/4 try 2/4 for a while
other then that the plant look great

she needs to be fed, the plant is taking all the nitrogen from older leaves and putting it into growing new leaves, thats bad. dont trim them, they are yellowing because the plants taking stuff out of them and putting it towards new growth, so you should let the plant take everything from them before removing them, if they come off with a gentle tug then its time, if not then leave them.

Evrn if i just added bloom its my 2 time i waterde with bloom can i still
add nitrogen

give it a really light dose of em now and next feeding time give them another light feeding of it.keeping your leaves alive far outweighs any *risk* of giving the plant nitrogen in flowering.(im assuming your in flower since you said your using bloom nutes currently) The people who say no nitrogen at all just cuz its flowering dont really know what they are talking about imo, giving it only nitrogen high food during flower would be a bad idea, but once in a while doesnt hurt, it helps keep your fan leaves nice and healthy so they can make tons of energy to put into the buds instead of suffering from n def. and dying or at best being less useful than healthy fan leaves..

you may have started giving bloom to early
its is ok to give veg nutes 2 to 3 wk into flowering
