My plants are 3 weeks old.i have not used any nutrients yet before i start i wanted to find out why my plants lower leaves are turning yellow then brown curling and die the tops still somewhat green.Ive done some homework and it seems it might be (mg)deficiency,also not enough oxygen getting too roots i used perlite but did skimp a little they are planted in 8oz plastic cups with holes poked on bottum i know if its oxygen too the roots ill have too trans plant with new soil and more perlite that scares me.I have floragro,florabloom,and floramicro plus a ppm tester and ph tester my HELP ? is which one should i try first and what should my PH and ppm numbers be at.Right now i have a gallon jar of nutrients mixed but am scared to use! PH reads 5.8 and ppm reads 646. i need too do something soon they are thirsty and i want to make a decision before i feed them open to any and all suggestions
