Leaf problems

[OldNewbie]

Hi guys n gals,
am having a problem with my first plant -
it is about 16 weeks old, from a feminized seed grown in a greenhouse
it has had a lot of buds on now for over 3 weeks but has not yet flowered

I'm sure you have seen this problem many times before but I am a real novice !!...hahaha
as you can see in the photos the fan leaves have started to turn yellow and shrivel, some of them becoming brittle

is it too much nitrogen or too little ? can you tell from the photos ?
should I flush it or feed it ????

some of it could be heat stress ?? as we have had days over 30degs recently

I don't have a soil tester

Buds don't look bad, fan leaves yellowing maybe maturing, hairs looking red, younger stuff looks ok so grow it out maybe flush to rid fertilizer before harvest

It's hard to get them to actually flower very abundantly, if you get a flower take a pic, some may not have seen

Thanks tiranger,
have just given it one flush in case I'd over fed it and hopefully it will flower soon. Will post piccies if it does
Will flush again before harvest

Looks like it is flowering to me. It's normal for a flowering plant to lose it's fan leaves as it comes towards the end of it's life. I wouldn't worry too much. High heat will accelerate this.
