I post this thread for my friend. He has grown some plants indoors and currently the plants are sick, spots on their leaves. Could anyone tell me what was wrong with the plants and give some instruction?

He uses smart pots in order to get healthier roots.

Is he spraying the leaves with anything? And is he using calmag? Looks like soiless...yes? Whats the ppm hes running and does he get good drainage at waterings?
