Hello, looks like PH Problems. If the newer leafs okay and the symptoms stopped no problem. If there will come more leafes in the middle and lower section like this on the picture i would check PH.

Foglie bruciate.Hey guys! Hope everything's going well. I have some burns on the leaves of just one plant, I gave it bio grow and top max biobizz. Humidity is at 50% and temperature is 27/30 °C unfortunately. I think it might be due to the lights being too close, but I wanted your opinion. Thanks a lot!

Carencia de Mg Flag-shaped leaves with yellow spots, no doubt a deficiency of Mg. The problem is that I don't know what causes it. I will do a soil acidity test to be sure, but I'm leaving the thread open for more experienced growers in case they could lend me a hand with this.

Browning tips and lower leaves Some leaves have a little brown on the tips, and some lowest leaves are turning yellow then brown, although I have been looking it up and it seems to be normal? It's not nutrient burn as I haven't given any. Any clues on what it could be or if I should be concerned?
