Day 32... 4.5 weeks.
No calmag given.
Last feed 1.4 ec
0.25ml per ltr silica
Level tsp mycho disolved
Hard water grow nutes.

Eurika moment: for autos it's all about light intesity in flower.
Photo period in flower only 12 hours to receive DLI, so can handle stronger light.
Autos stay on 18/6 or higher in flower, so need far less intensity of light to stop raising plant metabolism without co2 enrichment.

Successfully run with blue dream auto staying under 50k lux even with calmag.
If use calmag- no pk booster, just a little k supplement. P antagonist calmag.
Staying under 50k lux is the key with autos for me.
 
Next feed (tomorrow )

Showing signs of a little hunger on lowers since last feed (5 days ago), so raise ec to1.6.
These lower leaves were sitting a little in the dirt and also under a now thicker canopy, so would be sacrifed/stripped of nutes and dumped by the plant.
Early signs when stripping the leaves show she took mag first and looks like a little k later. Being mag (semi mobile) , k (mobile) from lower leaves.
So...change to hard water flower nutes for the k now transitioning to flower, also 50ppm or so mono mag.. silica, mycho .total 1.6ec .
see if I can ride the calcium train in my hard water, if not...got some cal mag on stand by...will use like the blue dream auto.

Lux: hot spot 35k...outsides 28k
100w board footprint too small now for consistent lux...300w bar light dimmed.
 
No mono mag, had mono trace mix delivered by mistake lol.
So, still no calmag given.

Plant fed.
0.25ml per ltr silica
0.6ml per ltr terpinator (k)
Level tsp mycho disolved
Hard water flower nutes.
1.6 ec.

Under the 300w bar light...dimmed to ~60%
Hot spot: 35k outsides 32k
Raise to 40k across the week.
 
Day 40, 5.5 weeks

Early signs of calcium deficiency spots appearing on what was last weeks upper leaves, so calmag given(yesterday).
Even though my water is high in calcium the plant is either unable to use it or there's still not enough.

not suprised though as the plant has been at full tilt this week, the roots have been filling the pot whilst the top has stretched 8" or so, also setting flowers at the same time.

Would've been nice if I could've played around with the mono magnesium to see if I could get closer to the 3:1 ratio of calcium/magnesium I wanted (currently about 5:1 in my water) to see if that helped process calcium.
Always next run.

Day 39 feed
0.25ml per ltr silica
0.8ml per ltr calmag
Level tsp mycho disolved
Hard water flower nutes
Total : 1.8 ec
