Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Yellowing and brown spots on leaves
Can anyone identify why this is happening? I am growing 2 other plants (one the same strain) with identical treatment and this started happening with one of my Royal Jacks. Everyday new leafs show the same symptoms.

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Calcium / PH issues? Did I take the correct steps?
Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.
