Advice about leaf colour

[Ish]

My plant's been doin quite well but 3 or 4 of the lower fan leaves are very pale green. I thought it might be cos i wasn't feadin it enough so i started to give it a bit more food but that hasn't helped. If anyone knows what could cause this i'd love to know or if anyone knows if the feed i'm using will work ok.

Most likely it's just because the light isn't getting to it and it's dying.Totally normal.
Is the plant getting ready to flower and thickening up?

I'd get some new fert. 20-20-20 somewhere around there.
miracle grow has one (all purpuse)I think.
Then flowering you want a diffferant level 10-49-15 sommething like that look them up .You'll find them.

Picture would make a world of differance.

Cheers for the advice so far i'll take a pic or two tonight and put them up. I don't think it's the light tho cos is't gettin about 14-16 hours good quality light a day. I read another post about yellow leaves bein due to over watering could that make the leaves pale green too?

Yes but if it's over watering there would probably be other problems like root rot.That makes your plant fall over and is pretty obvious.Only water when it needs it(first 2-3 inches of soil should be dry).
Depending on the strain and the stem structure ,the lower fan leaves can turn yellow and fall off it's totally normal.
My Blue Moonshine just did this.Now that the leaves are gone there is plenty of light getting to the lower buds on the bottom branches.See what I mean.Sativa is bigger and lankier and the squat little indica's get all bunched up, it's only natural to make room for light to survive and reproduce.

Well there's definatly no root rot or anything like that and i think i've only been watering it when it needs it so it's probly not that.

I've put a couple of pics on if that helps

thanks again for any advice

Yeah there not exaxtly the clearest pics lol but u can see what i mean. The top layers are lookin fine a nice consistant dark green just a few of the lower ones

After seeing the pic I'd say it needs some nitrogen.So get yourself some 20-20-20 nutrients.The 1st 3 is the nitrogen and helps the plant with photosynthisis.Like this.
