That looks like a problem by a low ph, raise that to 5.9 even 6 for a feed and see if that improves. I am pretty sure about that too my friend👍

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

Rusty spots mid-top of plants. A couple on each plant. Thoughts?
(Check diary for more details) Thinking calcium deficiency, also maybe magnesium deficiency on a few low yellowed leaves. Thinking it could be nutrient lockout? Feeding them 6.25 pH always. Gonna try 7.0 once and 6.5 for awhile. Thoughts anyone? Im still fairly new and learning

Handel es sich um Kalzium oder magnesium mangel oder ist das ein Pilz
It's Skywalker from Dutch Passion, now in week 3.5 of flowering. I fertilized it with Green House Feeding Grow at the beginning, and after the time change, I used Bio Bloom according to the manufacturer's instructions. The soil from Plagron has brown spots everywhere for the past 2 days.

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Possible manganese deficiency?
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.
