Cutting: right or wrong??

[Nikolaus]

Well my automatic ak47s are almost 5 weeks old and I notice some of the big leaves are starting to turn yellow.
I also noticed that the steam they come from are duplicated, by that i mean that the new leaves come from a new steam right up from the older and bigger ones.
My question is:
Should I cut the old leaves off so i can provide more energy for the new ones or should i let them die and fall down by theirselves?
Please experienced members, help me out!
Thanks!

It is likely a nitrogen deficiency. Nitrogen migrates from old growth to new causing first pale green leaves, then yellowing and withering of the lowest leaves.

If leaves are solid yellow they aren't doing much.

Thanks Lola,
Well, once in a while i use a 10-10-10 nut formula.
How often should i use the nuts? Everytime i water the plants? I do it like 2 times a day. And for how long?
Your answer seems pretty alright to me. And they're already flowering, so i don't want the buds to turn yellow for the next month or so.
Also the temps are high, but i don't know how to control it, as i don't have an AC installed on the plants room... Last time the temps were high to but i could manage to get a good harvest. Except i was trying White Widow instead of automatic Ak47

Please request adequate information and pictures before attempting a diagnosis.
There are many potential sources of yellowing.

The OP is referring to side growth. Don't remove leaves that do not drop on their own.
You are watering way too much. The pot should dry out and feel light between waterings.
REad the growroom setup sticky in that section about exhaust. You need an exhaust to control temps.

Start a thread in the 'problems' section that includes the troubleshooting form, filled out, and hopefully pictures too.

My dog ate my cam...
I'll try to use the cpu cam, but it might suck. I'm looking forward to post some pics again!
