almost looks like nitrogen Toxicity them leaves look pretty dark green to me along with the browning and burnt leaf tips just my 2 cents but id check for pest first before I went adding more or less nutes to be sure
yea haven't touched your as of right now but this is my second grow 1st one failed she hermied on me so I ordered a few seeds and that came out kinda scaring me lol
one drop if non bacterial dish soap or ivory soap to a gallon of water and buy one of them YELLOW sticky pad to hang in grow area..cover to soil with perlite or sand to stop the adults from laying eggs till ya get them under control
