Magnum auto in FFOF week 6 - deficiencies?

This is my first grow. Magnum autoflower in Fox Farms Ocean Forest week 6.
I began feeding one week ago each plant got 1 tbsp Dr. Earth tomato, veg, herb
My PH meter is broken. I have been watering with soft tap water left out over night.

Flowering well, is it normal to see all these leaf issues at this stage?

Whats “ soft “ tap water ?

No that's not what I would consider normal. What size are your pots? U could try making a tea with the dr e and hope u can keep her green enough to limp across the finish line.

Municipal treated river water.
I haven't had it tested recently, but I think it is relatively stable.
Here was my last test:

PH: last week meter reading says 7.4, meter won't calibrate now, I don't trust it.

Ward Labs tested sample 2016:
Total Dissolved Solids (TDS) Est, ppm 85
Electrical Conductivity, mmho/cm 0.14
Cations / Anions, me/L 1.4 / 1.1
ppm
Sodium, Na 12
Potassium, K 1
Calcium, Ca 12
Magnesium, Mg 3
Total Hardness, CaCO3 43
Nitrate, NO3-N 0.8 (SAFE)
Sulfate, SO4-S 3
Chloride, Cl 10
Carbonate, CO3 < 1.0
Bicarbonate, HCO3 33
Total Alkalinity, CaCO3 28
"<" - Not Detected / Below Detection Limit

Thanks for your attention Budzbuddha; I took my direction from your post below, I forgot to mention I added about 25% perlite.

Just over 3 gallons

Remember that it will take a little time for dry fertilizer to break down. Top dress FFOF will work faster as it is already ( ready to use ) .
I am on the fence about river water but sounds just like everyday tap ( municipal ). No need to gas off water.

You don’t do that with other plants . I use straight from tap - my cali water is hard as shit - but it waters my grass and cats drink it.
Mine chimes in at 7.6 ( ish ) @ about 350 ppm. It pretty much covers the Calmag issues since it is hard water ( high calcium / solids ).

My other houseplants don’t care either.

I would remove only the leaves “ touching soil. That can ‘ burn “ them too.

OK! I can make a tea! Thanks all for helping this nubie!
I am outgassing out of habit because my peace lilies are sensitive to chlorine.

Treat it more like a regular plant - nothing fancy.

Got it! A regular plant that drinks like a fish, eats like a bear, suns like a sports illustrated model, and only lives 10 weeks
PS: also never had to worry about humidity except with orchids.

Edit: no disrespect! I truly appreciate the feedback!

Update: I suspect the issue was fungus gnats.
You can see one of the traps in the picture.
I thought they just ate fungus, but discovered the larvae nibble on roots too and cause leaf yellowing.
It kept getting worse. I used liquid Bacillus Thurigensis, No luck after 10 days.
Added a cup of diatomacious earth to water and they all seem to be gone after two days

Thanks!

Update; fungus gnats are resilient! They survived Thuricide BT, and diatomacious earth treatments.
I'm not going to buy more "stuff"
I guess I will just live with it until harvest.

I learned something new.
Thuricide is wrong species of BT for fungus gnats.
Need Mosquito bits, which is BTi Bacillus Thurigensis israelensus
