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

Ugly leaves
So, guys.. I asked a question here, like 3 days ago, about some leaves. I think I have found out what has happened. Mold ignition, but very few, at the root. Have already medicated. Do you think this is a mold symtomn? Cheers!

Too much light or other deficiency
Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

Why do the leaves of my plants have brown spots?
Why do the leaves of my plants have brown spots? I have control over all cultivation parameters except for humidity, which has been difficult for me to control and is currently high. What do you 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.

2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦

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.

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!
