Without a diary, it is hard to say what exactly is going on from a couple of pictures. It could be a slight burning from excess nitrogen (burnt tips), but one or two brown spot are not necessarily a sign of anything major occurring. Remember too, no plant will have 100% perfect leaves, 100% of the time. Red/purple stems can also be a sign of nutrient excess, but can also be completely normal for some strains. Without a lot more information about what exactly you are doing and growing, anything more specific help is impossible to give. Hope this helps in some way,......... Organoman.

hi there, maybe you should try to give a check at the water ph. wait until the soil is dry and water at ph 6 and if u can give a look at the flush water u will get.
