Is this normal ?

Right so my plant is roughly 7 weeks into flowering (7 weeks from when i switched the lights) I'm using cfl's.
Recently some of my leafs started turning yellow so i pulled them off. Over the last week I've roughly pulled off 10/15 leafs and it looks like at least one new leaf starts going yellow each day. I know some yellowing is normal but is mine a bit to excessive ? i would say my plant has at least another 3/4 weeks to go so i don't want this to effect my yield. I haven't really given her nutes throughout the grow. I'm thinking this could be a N problem or sulfur.
So my options are give it some bio bizz grow or some top max if it's a N problem or i could buy some epsom salts tomorrow if it's sulfur or i can just leave it be. What do you recommend. I've attached pictures

Th ey could probably use a bllom fert, give it no nitrogen this late, it will ruin the flavor imo.

do you think i should use the top max instead of the bloom as it's a lot weaker. I don't wanna over nute it at this stage. I think she still getting some nutes from the soil etc

i dont know what top max is...your biggest worry now is not overfeeding... if you are worried about overdoing it just give it a lighter does of a bloom fert instead of a full does. I wouldnt be worried though about overfeeding it right now. You only got about another week of feeding time.... this info will have to go into the next grow

i would give it some ferts and stop pulling the leaves if it is a N def. then it will take it from the leaves so if you pull it, the plant will take it from another leaf. i push down lightly if the leaf stays down time to come off otherwise it will get green again in my exp.

leaves naturally start to yellow and die late in flower. leave it alone. let the leaves fall off on their own.

don't pull leaves off this is totally normal. next time as soon as you start seeing yellow leaves give it nitrogen for a couple waterings. Then switch back to bloom fertilizer. hid lights will help also. you might want to look into that.

Yellowing should only happen like that after you flush your plants and prep for harvest. Too late to fix it now but next time your plant shows signs like that earlier in flower, flush your soil, lets it dry out a little, then give it some bloom fertilizer that has a little nitrogen "1-2%" and a micronutrient supplement that has calcium and magnesium in its list.

i see some hungry plants. you need to give your girls some FOOD. but then your on your 7th week... so why are you even bothering to worry about some N deficiency? just let your plants flush and drain all the sugars off its leaves.

Okay well i will try and give it a weak solution of bloom nutes, flushing isn't really a massive worry for me as it's all organic nutes anyways and i will leave the leafs alone. It may be on the 7th week but it's still got a few left to go so don't want the whole plant to start dying from lack of food.

No nutes, It's called fading and it should yellow a lot more. When my plants are done every sun leaf has fallen off and the sugar leaves are just starting to turn. The burnt ash is snow white and the taste is delicious! just let it go...

Well I've gave 1/4 strength bloom nutes earlier will it still be okay ? I know some leafs yellow etc i just thought it was a bit much yellowing so just wanted to check. But i think she must have at least a few more weeks to go as she hasn't really packed on any weight yet
