Crispy brown leavesnorthern light is showing yellow and brown leaves at the top and the bottom of the plant. These leaves are thin and crispy like if they are about to fall off. I am watering it 2 to 3 times per week and started adding a bit of cal mag last week when they started showing brown dots

Suggestions as to why this plant is a mess!First grow - Blueberry Auto outdoor. Pathetic thing is on day 36 from direct sow. White splotches since week 2. Subjected to excessive heat, an oversized garden bed, lack of sunlight and overcompensating with supplemental grow lights. CoM organic nute/soil. Any solid diagnoses?

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?

Browning leaves sections of leaf surface discolouredDay 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice.
Thank you for your time and all answers are appreciated. Have a great day!

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

So our upper leaves have been developing some burn along their edges but are now yellowing too. I've increased the gap from light-plant to 75cm but is there more to it? Unlikely a deficiency as she's fed 1/4-1/2 recom. nutes every water. Root ph is ok so maybe nute lockout? Chur.Week 11

Rusty spots mid-top of plants. A couple on each plant. Thoughts?(Check diary for more details)
Thinking calcium deficiency, also maybe magnesium deficiency on a few low yellowed leaves. Thinking it could be nutrient lockout? Feeding them 6.25 pH always. Gonna try 7.0 once and 6.5 for awhile. Thoughts anyone? Im still fairly new and learning
