I have the same problem with mines, by any chance can be from the soil? too compressed or not enough breathing?

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

flush in flower?
I'm starting on my 4th week if veg for pink runtz auto. I'm using fox farm ocean forest and happy frog for soil and nutrients. I know ocean forest has a lot of nitrogen and I was wondering if I should do a flush around week 2 of flower and then add bloom nutes.

Now I really have a more serious problem. I would say I'm experiencing a nutrient lockout. Does anyone know what it is? I'm going to water with enzymes to see if I can clean out the excess.

HELP—Trained eye needed for a nutrient deficiency diagnostic!!!—HELP
Can anyone help me with diagnosing what appears to be a nutrient deficiency? I used Jobe's fertilizer sticks (13-4-5) [I know, horrible stuff but its all I could get for the next two weeks] which I diluted to 1/8, 1/4, 1/2 of the recommended amount as per label. CHEERS!

Mango Smile should i add some nutes or i can just give more of what i use?
I'm feeding this Mango Smile more than all the other plants, but it continues to be the only one with deficiencies. It's being fed with CalMag and BioMagno Bloom OM, but it doesn't seem to improve. For the other plants, I give half the recommended dose, but for her, I give the full recommended dose. Any advice?

It's been 4 weeks since I stopped fertilizing thinking I was closer to the harvest than I actually was. Should I start fertilizing again with some flowering nutrients or leave it as is? More than half of the trichomes are milky.

I just gave biobizz bio grow because that's what I have at home, 4 ml per liter. We'll see what comes of it. There are more and more yellow leaves.

Not sure about deficiency, thought was Calcium or Magnesium but not sure anymore.
The nutrient deficiency is back so I gave it another double dose of CalMag to see if that can stop it in its tracks but I am not positive if that is the specific problem. Added micronutrients mix as well to see if maybe that helps. Any suggestions would be appreciated.

Defficiency or light burn?
I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here? Ive added a tiny dose of calmag, can I supercrop this late into flower?

NEED HELP :(!
first time I see this problem, I've only watered with Grotek's Cal Mag and a few times with the BAC vegetation base at 1/4 of what the manufacturer indicates, always with a pH of 6.0 and EC 600-800, but the residues show 1800-2800 EC and a pH between 4.0 and 5.
