2.5 wks into Flower first grow. Hows she look?

The female came out of a bag of killer weed. The taller male was some mids and I have killed. The edges of some of my leaves are dead. Could this be nuit burn? I have been using 2 tsp of Tiger Bloom per gallon every other watering. Been using about a half gallon every two or three days per plant (Soil). Since flowering, I have been keeping them outdoors except when it drops below 50 overnight (SW Florida). Any tips or just keep going as Im going?

Thanks

keep doing what you have been doing
