Please can someone tell me tips for growing autos ...

hey mary, good question ! the newest lighting technology is basically what is called "fluence-like" lights, LEDs that can increase yield 30% from HIDs ! all the newest LEDs basically have warm white for veg and cool white for flower, so no more of these purple lights. what's the color of the sun? is it blurple ? anyway I'm getting some of these next gen lights from nalite in china http://www.gznalite.com/grow-light-bar/pl024.html check it out, see also @silverback_guerilla he shows these lights in his latest grow, and it's a very nice grow ! for nutrients i stay bio always, and i'm not using liquid fertilisers anymore, too much pressure and it's hard to control, just mixing some home made powder for veg 12,3,3 and powder for flower 3,10,10 into the soil then plain water with a cal mag +kelp foliar spray and some amino acids during end of veg and mid flower... see @mad_scientist latest grow on GD for the technique... it should be easy ! anyway i got some biotabs aswell and i'm just following their schedule because it's really easy and it works really well with some autopots, but autopots are not necessary... see @biotabsf69 thats the official account you can see how well and how easy it is. That's just my personal experience, hope this helps ! 🚀
