My current grow is Bomb Seeds THC Bomb Auto. This is my first grow using LED. I am at day 60 now, and about a week ago, my girls stems turned a bright neon green, while all the leaves are a normal dark green. The plant is growing flawlessly, no deficient, pH 6.8 and seems to run between 6.3 and 6.8 depending on the moisture level of the soil. I am using AN Jungle Juice with the hobbyist supplements. Been adding 1 ml/quart CalMagic with every feeding. Anybody ever see this before, and what did you decide it was? Is this common with the use of LED? Never seen this before, so just wondering whats up. Thanks.
