Looks like acid burn. Maybe a drop of nutrients hit the leaf?

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!

I have this symptom, a pattern of rust spots happening on new leaves, I have checked medium PH, which is around 7.5. I think it is Boron Deficiency caused by The medium PH not being approximately 6.5. I need more suggestions, What do you guys think?

Top leaves turn dark and curl - What can I do?
I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago. Mid last week I started noticing some burn a the tips, so i dialed nutrients back again. By this weekend the tips of the leaves curled further and turned dark. The rest still looks a bit pale, but buds look good.

Why are there soon many brown spots all of a sudden in WK 7?
I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

Leaves brown down the length of half the leaf
I have some leaves that have gone a bit brown down one half, but along the length. See them in Day 40 pics (I have added a extra comment there). Does anyone know what that is? I was thinking maybe it is just the bits that have been sitting under other leaves, but I am not so sure

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.

Which pests do this?
Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?
