You might want to do a flush, fill with cold water, and then keep that water below 70. Don't overfeed, and make sure your pH is in the correct range. Water temps are really important for roots. I keep mine around 68, and go entire grows without a single flush.

Hi, added a picture of plant. There is seen some spots on lower leaves, but they have been there awhile and it has not gotten worse.

Water temp is 21C (69.8F), it was way higher before i got my portable AC unit installed in tent few days ago. I just put -1C in the settings so it should take it down a little bit more and keep it that way.

Seems like a must have for hydro grower. Ive done some research, cant find a place to order it in EU

Maybe Hydroguard? It's not nearly as concentrated.

Look for products that have a significant amount of bacillus amyloliquefaciens
 
agree with above either go hydrogaurd or h2o2,either way.Its probably been the high temps of water thats done it!!get the roots sorted first and water temps,then see if spotted leaves get worse,and take it from there.
