Amnesiaaa haze

Hello Both plants were supposed to be amnesia but they look different, like different strains plus one is sooo much faster than another. Maybe I'm trippin. I'll add more nice pictures later on instead of under hps light photos. Last 3 waterings were using plain phed water. Didn't help for tip burning. In next couple days I'll use maybe just a lil bit of pk 13/14. Whatever they'll ask for
