Beginner: Hybrid tea-rose sunburnt leaves or fungal infection?

Hello everybody! 
I am new both to gardening and to this forum, so please be gentle if I get something wrong I may not know it. Also, I am not an native English speaker so my gardening terms and explanations may be primitive. :) so here goes my first problem: I have recently bought and moved to a ceramic pot a pale pink tea rose hybrid. The soil was especially for roses and I also bought a gel-mineral base also designed for roses which I used as instructed once a week. I watered the plant daily just enough and it received 6+ hours of direct sun (temperatures a little bit high I think). So far, so good. After two weeks (meaning these days) I noticed that some leaves have turnt like this -> see photos. I don’t know if it is sunburn or fungus or anything! I also searched the internet for something similar and I didn’t find an answer(or maybe I don’t know where or how to ask).. I don’t want to lose the rose as I’ve read that these types of roses are very hard to maintain and that’s why every change stresses me a lot. Hope you don’t mind looking into this and giving me some advice. 
Best regards, 
Allie

    Welcome @Sunnyrose :)

    My instinct is the same as yours ... that they've been sunburnt ... possibly the plant was kept in a more sheltered spot at the nursery.   

    However @Marlorena is very knowledgeable about roses ... hopefully she'll see this thread and give you some sound advice.

    It looks scorched to me.  What country are you in?  When you say the temperature was high, how high?

    I call that fertilizer burn due to excess salts in the compost, which means you've over fertilized your rose...  a simple repotting would have been sufficient, without any extra feeding until the rose has re-established itself in the pot...  I note you have been feeding with some mineral gel once a week...  what you need to do is water the pot thoroughly to try and remove the excess salts, and pinch off the worst affected leaves, and do not feed until it produces healthy growth again..


    Otherwise, there is very little wrong with your rose, and nothing much to worry about...  it's a pretty rose.. 

    Please make sure you have sufficient drainage holes at the bottom of your pot for the water to drain away..

    Due to personal privacy issues, I’m not yet comfortable to disclose this, hope you don’t mind, sorry. However, I can say that it’s Eastern Europe and the temperatures were over 30^ C

    The reason behind all my extra care is that 5 years ago I had another mini rose bush and after two weeks it completely died and that was the end of my   trying to keep a flower in a pot.
    I will do as you said, hope I’ll keep it alive and healthy. Thank you! :)

    I agree  :)  and if you're worried about your rose don't hesitate to come back and ask more questions.  :)
