Hi!
I have 3 blueberry auto flowering plants. They are currently 5 weeks old today. I noticed a week ago that tips of leaves were turning yellow at the top, I came to the conclusion this was the start of nutrition burn so have just been giving them water and ‘power zyme’ on feeding this week. (Advised by another grower)
The nutrition burn seems to have got better but now the plant seems to be dying from the bottom up, the leaves are drooping and dying. I believe they have just started flowering so maybe this droopage and dying of the leaves is normal. This is my first grow.
I’ve attached pictures of the plants. Any idea what may be causing this?

Currently;
Temp - Around 23 Degrees
Humidity - Around 40%
Light cycle - 20/4
Light distance to canopy - Around 20in

Is moist under the surface currently. I tend to use that as an indicator as to when it needs more water.
I’ve also attached the soil that I use, I was told it was good for auto flowers

I have never grown autoflowers but it look to me like they need water,usually droop is from over or under watering unless you burned them with ferts. Maybe take one and water it and see if it reponds,it should quickly if its underwatered

Yes, do you recommend a certain type ( eg scrog or just tying down)

Yep. And pots not raised up. If there is a hole in the bottom. Just makes it tough to No what is going on at the bottom of the pot.

With no drainage it could be bone dry the top third and soaking wet the lower third. Just two cents.

The purple stems and fan blade discoloration look like Magnesium def.
I would get a meter so you can water correctly and add some Epsom salt next time .
I don't grow autos but you have limited time to make this plant its best .

I haven't seen mention of water type or PH...

What is your water source? Tap? RO? Natural spring? Toilet?
Have you been checking/adjusting your PH when you feed/water? What is your PH?

Your roots are poorly developed from a poor calcium:boron:potassium ratio. Excess calcium is keeping photosynthate from moving freely within the plants.
