Lower branches dying, Is this normal?

Hi my plants have gone into flowering but the lower branches have begun to brown out and die, is this a nutrient deficiency or is it relatively normal for an outdoors plant?
Just worried it’s a mobile deficiency that will ruin the rest of the plant but I don’t know anything about them.

Absolutely not normal op...better check fast and hard for pests, either at the root zone, or on the plant itself, everywhere.
Also, could be root root, check your root system, smell them. Are they brown and smelly?
That plant is definitely in trouble.
Good luck op.

What is your watering schedule, routine? Ph? Nutrients?

Edit to read root ROT sorry.

It's lack of nutrients to the plant.
Root rot, PH problems or lack of feeding ........ hard to tell.

Hi thanks for your reply, I water with 8 ml of GoGo juice which is an organic fertiliser and also ag grow bloom nutrients but I’ve recently cut them a bit because I was getting nutrient burn , this is my first real grow so I’m pretty noobie

I feed them once a week and then give them water every now and again too, ph is 6-6.5

Ok you need to ph water to around 6.5 for feedings, waterings. Then allow pots to dry to approximately 80% of the weight when freshly watered. It is referred to as the " lift " technique for checking moisture levels in medium.
Every once in while will not cut it.
These plants love a wet/dry cycle, it allows a natural ph swing for elemental pickup by the roots, also allows oxygen to reach them.

Forgot to mention I live in western Australia, the plants have been suffering from heat stress , I water them whenever the soil is dry about an inch deep

Oic I hope you and yours are safe, and I'm sorry for what your country has had to endure.
You can shield her from extreme sun with a shade canopy of some sort..filter much of the intensity down during the hottest part of the day.
Try to keep the pot shaded and cool as much as possible.
Beyond what I have mentioned, I dont know how you should proceed.
Plants in extreme heat will drink more, so are very prone to over fertilizing and lockout due to salts building up.
Leach soil if suspected with 3 or fours times the volume of the pot with fresh clean ph'd water. Once this has drained out, follow up with a half manufacturer's recommended nutrient amount in your water, ph to 6.5 and feed.
Hopefully these suggestion help op.
Maybe a fellow Aussie with experience in your climate can chime in.
Good luck op...really.
