I want my candys

Hello. First, I want to say both of the previous answers are correct. Deficiency can be caused by too much nutrients, and you do have signs of overwatering, however the most common mistake is incorrect ph. For soil, I agree with @ValhallasGarden that 6.5-6.8 is the range you need to dial in. This is most important. Second, @Athos is right about letting the plants suck up existing nutrients from a nice, healthy potting soil. You should not need to add much nutrients in the first 4-5 weeks if you start with good soil. Then, you add small percentages of recommended nutrients and watch how the plants react. I have been guilty of going overboard with the nutes and using incorrect ph multiple times and it always turns out bad. Less is more with nutrients in soil. Good luck, and please pick one of the other guys as your grow answer, not mine. They provided the answer between both of them.

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 ! 🚀
