'rips' on leaves
Leaf damage between the veins only found it on two older leaves, had problems with calcium and magnesium deficiency early on, could this be a symptom of that or what else could it be? Haven't found any pests..

New brown spots
These brown spots came out of nowhere, all over the plant. Had no issues with spots up to now. She’s 4-5 weeks into flower, recently started canna terra Flores every other feed. Also added some seabird guano recently. Please let me know what you think and thanks

Early signs of Calcium deficiency?
See a deficiency here? The whole leaf is very mildly spotty, like just a shade off... seems to be getting worse but very slowly. I had to filter the pics I took, were over exposed.

Nutrient burnt leave removal question.
Should I remove all the burnt leaves? Worst ones are 25% burnt. Some just speckled throughout. Do the flowers still need exposure to the sun? Or will the leaves exposed to sunlight keep the buds growing? Can cutting the burnt leaves cause enough stress to hermie or stunt growth?

So... the brown spots in the last 2 photos. Are they Ca deficiency? Will I do extra damage if I add Ca/mG supplement? What is the upper concentration of Ca/Mg concentration for cannabis in DWC grow? How can I tell if I add too much Ca/Mg? Help please!

Deficiency on Leaves
What kind of deficiency causes small white spots on the leaves like this? Also on the lower leaf it's a bit mottled and yellow. I think it is two distinct problems.

Do these random spots mean nutrient burn/deficiency, or is this normal?
I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

Help me Gods of education
Hello boys and girls ✌️ Could someone help me on this green decoloration. I raised to 300ppm and the conditions stay the same as above. I just sprayed them with tap water (6.7pH) for like 3 days to raise some humidity. Could it be related? Could it be a lack of nutes?
