Looks like nutrient burn. She’s a little high in nitrogen. Water feed for a few days and convert to a bloom tea for the week.

Please have a look at these leafs! I gave a new dose nutrients by wormcasting rockdust and guano. Also some seashell chalk. I waited a bit, but it seems to continue spreading, at low pace.

Is this overfeeding or another more complex problem
This is my first Automatic plant culture. I've made some novice mistakes, such as topping the plants. They start flowering about 2 weeks ago, but the leaves are turning yellow with some brown spots. I feed with an old Nutrient I had here. Can that be the problem?

Leaves dying
Last week I noticed that the leaves were starting to burn on the tips and added a question here. Most ppl said I should give less nutrients so I started giving only 800ppm (I was giving them 1000). Today I noticed that the leaves were like this.

Dry spots on sugar leaves, plant late in flowering, also spotted on another one in the same reservoir
Hi guys, my plant is around 2-3 week before harvest. What is the cause of the these dry spots on some of the smallest sugar leaves on my plant? The ppm might be too much and is around 1200-1300ppm. PH is 6.0-6.1 I've spotted it on one other plant in the same reservoir. Thank you

Should I cut the dried leaves at the bottom?
Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.

Super Yellow Leaves in Mid/Late Flower
Does this bottom left plant need more nitrogen? The last two waterings we've given it 1.5 ml/liter of Micro. Should we give it more? The other 3 plants of the same strain are much smaller, much darker green, and further ahead in flower. These Blue Dream autos are 51 days old.

I have tried to figure out what this could be without much luck... it seems that my leaves are having a slightly yellow tint to them under the grow light. Under normal light it seems ok, what could this be? Overwatering I am guessing but not sure.. Any help would be appreciated
