Hey yall! Im new to growing and this is my first plant. Picked her up about 2 weeks ago. It was a clone from a local shop here in arizona. Plant seemed to be healthy until recently. Its now drooping a bit, as well as developing a yellow color on the edges of its leaves. what should i do to correct this? Strain- platinum kush breath Media- fox farms ocean soil Water- distilled Grow light is 18in above the top of the plant on 40% ACinfinity 3 plant kit. I have done some research and believe it is most likely due to a calcium and magnesium deficiency. I went to buy Calmag just in case. Any advice would be greatly appreciated!
