if you see something SAY SOMETHING

high temps, humidity issues or potasium, leaves looks strange. guess watering issue too, i see you dont saturate pot fully, see some blue granules, is it against snails ??? what for so many white stuff, is it lair of perlite ??? too many questions, hard to understand or tell. most leaves colour is nice, plants a bit small, branches lanky, so either root system didn't developed well, or weak light, or bad feed regime or diet. small tunes ups needed, without two way communication is hard to go through all things that would make grower to wonder why you did or havent done something. dont stress, read, compare, time and many grows will do you are pro, or mistakes will make you to know more ;) i dont know one grower who havent done something wrong, each grow is a new lesson... have fun, dont stress !
