I agree here....first of all the FFOF is hot out the gate... And the nutes 1/2 strength Is too much yet....give it another couple of waterings with just ph'ed water and she should be fine.....don't forget you shouldn't have to nute in the first 3 weeks with FFOF....theres no way it's def...already.... They will be fine...get LSTing my man...it's time...word

Yeah def nute burn, always remember with growing weed it's always best to under do something then over do it! the soil i use gives the plants all they need for the 1st month or so then i start in a 1/8 strength nutes every other watering.
