looks like nitrogen deficiency and calcium deficiency. Judging from the looks of the whole plant I think I can tell your ph on your water is off which might be causing nutrient lockout.

I check my ph(with ph meter) before i water, making sure its at 6.5 or 6.4. I give the recommended dosage of Bio Grow, as it is an autoflower. I also checked the run off and its normally at 6.5 or 6.6

yellowing leaves from the bottom up is common at finish. if you'd like to try and prevent this i would wait until the next run. Add more nitrogen before this point. Once you see the problem its something you've missed for a couple weeks already. your plant does not need a pile of nitrogen right now.

Add some Calmag from now on at 4 weeks. I also like using Kelp based additives ( Dark Energy/Super Nova) for micro-nutrients Always have some nitro in your feed solution, as some don't use a lot in the bloom stage, and that looks like what you have. That is what I see, a def in N, and possibly Calcium.

looks like the way a plant finishes up to me. they naturally turn yellow when they're at the end.

Yea they do yellow near the finish least but he is not near finish. Are u using calmag? Is it RO water? I use GO wit RO water 15 ml/gl , anyless and i syart to see the same thing

hes at 6 weeks. Should be close right? idk, i don't mess with autos. Ya your right though, theres no mention of calmag in his post. To me it looks like nitro, and it looks pretty far into it. I also like about 120 ppm calmag all the time. its almost macro nutrient status.

it appears to me that u cut her N off too early. I am not framiliar with the exact NPK of the nutes you are using, but i continue to feed veg quantitys of N untill week 2-3 of flower and then slowly cut it down until they are done, my last feeding before flush (about 7 weeks or so) i cut off N nearly completely, but the plant still needs N in early to mid flower. You dont want this yellowing effect in my opinion at all, but def not in week 6.

Are you using an abundance of flowering nutrients or a balanced feed? To much P and K can lock out many things. Keep it balanced throughout the grow with a slight decrease of N late flower to keep a happy healthy plant.

Typical nute burn.. would check ph, then flush then add calmag and check ph and then see what happens.. bit it does look like nute burn obiously ph has alot to do with it also.

Looks like a PH issue. You have a mix of nute burn and deficiency. Looks like you saw the deficiency, increased feeding and burned with the available nutrients. Check PH with 2 methods, your meter may be wrong. Double check with a chemical test or another known to be accurate meter.

I don't know what the problem is but it's not singularly N. Nitrogen will take one or two leafs at a time then move on to the next leaving as much healthy foliage as possible. What and how much have you been feeding? Using tap water? Are you letting the chlorine evaporate? Google Chlorine Plant Toxicity and check the images. What are the PPM of your water?

Also, if it's yellow or brown cut it off.

don't cut it off. gently pull it off when it wants to go. you don't know what his ph is. you also don't know whats in his root zone. OP have you ppm"ed your run off? theres still more questions to answer before slashy slashy happens.
