My plant is in flowering stage and a strange yellowing of (mostly) bottom leaves have started happening. Maybe lack of magnesium problem?
Help me please diagnose my plant problem, see pics

Yellowing is usually a sign of a nitrogen deficiency.
In your case I'd say it is okay as this is normal to see later in flowering, with lower older growth.

jimcz, put up more info. what soil are you growing in, how big is the container, what fertilizer are you using, how much of it are you using, what room temps like? I think I know what the problem is but need to know more info.

It's soil mixed with some perlite, in about 12L (3 gallons) pot. 2 weeks ago I started with flowering food, 18:6:28. I usually put about 4ml from each bottle (see pics) into 1L bottle for watering. I water every other day and I put food into every other watering. Temp is high, it's summer here, can't do anything about it. But I don't think it's heat problem.

Over fert.

Could be a root issue. Is there a funky smell?

skunkpunknz, he's growing in soil, not hydro. bad smell is very unlikely.
jimcz, you've been feeding 18:6:28 every 4 days or so. It's over fert. You shouldn't be using such a high NPK ratio fert anyway. How can it be under feeding when you've been feeding them like crazy?

Dude you have like five different answers. I dont even want to add my two cents because its differentEh. Thanks for your feedback but it's hard to choose which opinion to go with. One says hungry, the other one over fed.
.....but i will anyway. Id say change nothing. The top of the plant looks healthy, green, and not burnt. It looks like your losing like the lowest leaves? Thats pretty much normal impo. The plant just sheds a few lower leaves, in veg you may lose a couple but in flower you lose a few more. If the top and middle stuff looks fine, and it does, i wouldnt sweat it too much. If your not adding calmag then do that, but other than that little bottom self pruning the plant is doing, id say they look healthy.

Plants do not "self-prune."

have you ever grown a plant? My plants like to kill their own leaves off if theyre not getting enough light, like on the bottom or center. Yours dont? Or maybe you dont lose a leaf until you trim it off after the plants hung and dry? And if you dont quote my post i cant see if your talkin down at me polak
