Where are you? Looks like heat stroke, you'll need kelp for heat stress.

Sick leaves, good buds
Some leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest. I know that ripen helps to end life and makes the leaves turn yellow, but not so!

Older leaves turning brown and crispy?
Older leaves down the bottom of the plant turning a bit yellow on the tips. Should this be a cause for concern? All rest of the growth up the top are looking very healthy though

Why does my pH keep changing in Germany? I set my water at 5.9 then it shifts 3-4 times over few hours, causing lockout if I water my plants with it, In Ireland, I never had this issue. Using Advanced Nutrients A+B, Big Bud, Overdrive. Could German water be the problem? Any fixes

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.
Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

Leaves not looking healthy
Red spots and leaves curling down. I had some poor soil with low acidity to start with and put in too much neuts at the beginning. Not good. Been giving it lots of PH water to get run off correct, probably too much and I now see some red spots on the top leaves.

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.
I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency. However, only the main cola is affected now. So I also suspect light burn. What's your opinion?

Help with issues ID
I have a photoperiod in a 5 gal using BAS light. It is currently day 3 of week 4 , and I'm getting some damage on the tops. Would this be light stress or another issue? The tips are starting to go light green. Using the 200 watt light for the 2x4x8 ac infinity tent.

Possible nutrient burn ?
I’m pretty sure this is nutrient burn but it’s weird because I’ve only given a tiny dose of nutrients so far. Less than a quarter of recommended dose and probably less than I’ve ever given an auto before. What do people think ? Nutrient burn ?
