Why are some lower branches dying off

I keep having lower branches die off on this plant and there's no sign of damage at all I just come out and one lower Branch will be totally wilted like it hasn't had any water in days water in days

Could it be dry spots in soil. Ran across this on you tube and looks familiar

Yeah I guess maybe it could be it's been really super hot here I give him at least five gallons of water a day they're in 45 gallon grow bags quite strange I hope it doesn't keep going up the plant they're beautiful buds

I would water once then come back in 30 min and do again

The heat shows.Sunburned?

Double check pests?

The simplest and easiest thing to do and could very well be the fix. I would consider you only dropping 5 gallons of water in a 45 gallon pot the reason this is happening. Common standard is watering a pot at 1/3 or 1/4 its capacity. Which in this case, for your 45 gal pot, you should be in the 11-15gallon range...this is to fully soak your media...you probably have necrotic spots in there because you have little pockets of these 5gal daily splashes...

yep I missed that on the 45 gln containers and only five gln then I would say dry pockets

I've had lower leaves and stuff die off before and the reason for this was because the bottom of the plants weren't getting enough light. I don't know if this is the same problem you have. I'm just throwing ideas out there

Hey there everyone, I've seen this in multiple different gardens and with entire populations. I'm pretty sure it is "salinity stress," and may be happening due to heavy well water, calcerious native soils, or salt bond partner buildup from salt nutrients. Salinity stress is confused for verticillium and other pervasive wilts in vegetable crop.

Basically, solution pressure in soil for these salts is so high, the plants must uptake some amount in order to drink at all. The lowest branch or first divergence from the xylem is kindof getting dumped on with salts, until they are so built up in the tissues that they're causing cell lysing and death, and the branch eventually wilts.

Consider this a guess.

Edit: check out this article: https://www.marijuanatimes.org/sodium-is-on-the-podium/

"Some plants have evolved mechanisms to combat toxic build-ups of salinity by collection and extrusion, compartmentalizing excessive salts in vacuoles, or storing the salt in lower, older leaves."

Thanks for all the feedback I watered the piss out of them

You need to scope the underside of the leafs, on the lower part of the plant.
