I vote light burn. The brown/burned tips seem to be only on the very top of the plant while the leaves further down still look good.

Hey mate ! That don’t se mens overwatering, but overfeed ! In my opinion , you have a nutrient burn, and maybe a light burn too, are your tent to hot ? Or your plants to close to the lights ?
First of all, you can flush the plant, after that give nutrients again but 1/3 of the dose and increase gradually

Is this a disease caused by a lack of calcium and magnesium?I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

Photo named Day 7 Zoomed, I have been seeing these dots for 2-3 days now. What is it? how can it be solved?
FYI - These were the first set of leaves, others look healthy.

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!

Emerging Issues - Week 9At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Brown Rusty DotsWhat are these brown dots on my plants? They are only on one of the plants, they have gotten a spray with Dr. Zymes Eliminator and had no effect, also did a mL of Cal Mag in its last water with no effect and getting worse. I’m not sure what this is and I can’t get it to go away!

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.
