Yellow underleaves dying during flowering normal?

Ok basically as you can see the bottom leaves are yellowing and falling off. Im on day 26 of flowering and feeding schedule so far is 1ml biobizzgrow and bloom for first 2 weeks and now week 3 1ml gro and 2ml bloom. My nutes are over 1-2 years old so im not certain their working so would like to check if my yellowing is normal during flower? Or should i get new nutes. Oh ps I also added 3ml advanced nutes revive start of this week for essential nutes like mg.

a top shot

I imagine its all good dude the bottom leaves are just missing out on light or getting old the bottom leaves it is always normal for them to drop at some point

yea, this happens as buds use the nutrients from fan leaves, causing them to turn yellow and die off. As long as the buds look healthy i wouldnt worry.

ahh ok thankyou very much for your answers. So do I just prune as soon as the leaves start to shrivel up? Or as soon as their yellowing?

matter of preference, most ppl say wait til they get to where you touch em n they fall off

ps some guys in chat are saying they think I have a mg deficiency. I did water with advanced nutes revive at 3ml per litre start of week. That contains mg so is it likely they could be right?

oh and sorry to keep posting here but is it really normal for plants to leave leaves in only the third week of flower? Everything else im reading says if they have enough nutes they wont yellow until final weeks when you flush and they extract last nutes from leaves. WHich leads me to believe i need to get new nutrients fast!

I wouldn't worry about the bottom leaves as they are not getting enough light. However I would grab some bamboo and keep your colas in a circle and allow for light to get to the middle of the plant. Best looking colas get light from all sides including the middle. Bottom leaves I pick off but leave the leaf steam in place as it holds nutrients

Ok thanks guys. Ill just keep doing what im doing then!

Dont leave the stem! The stem carries nutes to the leaf and Co2 to the plant from the leaf. If the leaf it dead and there is still a stem, yer plant will try to repair the broken leaf, wasting nutes that should go to yer bud! But if you cut the stem off, as close to her as possible, then those nutes are no longer wasted and go where you want them to, TO YER BUDSSSS!!!!!

I thought id add a picture. Ive bought some fresh bio bizz grow today to see if i can halt the yellowing till im ready to flush! Id guess its better to keep nutes in the leaves till then for the fattening up. What do you guys think?

Dont add n-e nitrogen
