Not sure if this is normal...

So this is my first time posting, hopefully someone can lend me a hand...

Here are some pics of my lady, she's about 3 weeks into 12/12 (probably more like 2 into flowering...flowered her early...) and until today things have been looking up...

I went to check on her this afternoon and I noticed an increasing amount of what's seen in the pics...

I know as plants get along in flowering the bottom leaves turn yellow, but these are now showing larger brown spots on the insides of the leaves and curling upward and dying...

I'd expect at least another 4-5 weeks in flower so if this continues at this rate, I won't have a plant left in that time! Please let me know what you think and if there's a problem...

add some veg nutes to your flower nutes for next couple of feeds

hit it with some nitrogen and it will bring back the dark green you want it to have....now if you started flowering the plant and its over a week into flower then yellowing of the lower leafs is normal...what light cycle you have em on? and no matter what you will lose some lower leaf...it just nature
heres a pic of completely normal flower time yellowing...when the leafs yellow it can one of 2 things....it could be the plant using the food that fan leaf provides, or it could be a nitro defficiancy

if its buffing its norm just pull the yellow ones out their taking much needed energy for buds

yellowing of the lower leaves is not normal at 3 weeks into flowering.

the bad thing about using flourescents is the light diminishes very quickly and if there is no light within 5-7 inches of the leaf then it will not be getting the light that is needed. I normally keep lights within an inch or two. If its possible spread some light around the middle to the bottoms of the plant...I do not know your light placement or the convenience of doing this in your area...I tend to see more yellowing of the leaves as I have to spread lights due to growth...The curling of the leaves is more than likely a nutrient deficiency, there are posts that have basic syptoms to help you diagnose your plant, I will post a link if I can find it. As I said your lighting may be fine, I do not know your setup, so the yellowing of the leaves could be a nitrogen deficiency...

Thanks a lot for the input guys...the plant overall is rather small cause I was just trying to get my feet wet in the growing game again so I quickly pushed this plant into flower...I have 6 CFLs on her so she's definitely getting the light even to the lower leaves, but recently I backed off the veg nutes cause I figured they wouldn't be needed as much...guess I was wrong! I gave a nice dose of some veg nutes and plucked a few of the really bad looking leaves so hopefully after a few days she'll be back to her old self...I'll post more pics in a few days. Thanks again!
