hello my coffee plant sadly just keep get worst and worst first all the new leaves started to grow light lime green with dark veins as you can see at some of the pictures, then those leaves started to lose all the green and became whiteish and yellow.
two weeks ago i transplanted it to bigger pot as in the pics, but now it started to get black and broown spots all over the leaves, may it be because the higher he is now? sun burns ? and what deficiency is he suffering from? thanks ahed for any help Crossing Fingers!

Several possible issues here. Did you move it from indirect to direct outdoor sun?

Have you checked the pH of the original soil?

How much of the original soil did you remove when you repotted?

Excessive heat compounded with dry air can be very damaging. Are you keeping it inside or outside?

How do you decide when to water and how much do you provide?

Thank you for the reply, first of all i bought it half year ago and since then it was outside and it was outside at the nursery back than, i checked the soil ph it came out as 7, i didnt remove any soil just burried a big hole and potted the whole root structure to the best of my memory it outside in my balcony with soth west sun light, most of the day and i water when the top of the soil seems dry water until water spills from the buttom of the pot..

In my experience with one coffee plant about 4 years old, it is a very thirsty plant and seems to dry very quickly. Maybe it had been getting too dry between being watered. Now, this may change since it s repotted.
Unfortunately, I am pretty sure the yellowed leaves will not change back to green.
Plant it and they will come.

Outdoor direct sun is too much for it. If you had kept it outside in a shaded location it would not have so much leaf burn.

The pH is too high and should be closer to 6 so the nutrients in the soil are available to it.

The repotting has made proper watering more difficult.
