First Time Blueberry Autoflower

I think a lot of our plants have the newest growth come out as almost bright green/yellow and slowly as the leaf ages it turns into a more natural green. However an iron deficiency coupled with possible ph fluctuations can cause that same new yellow growth. Hows your calcium intake? And ph? Is it staying fairly consistent? Ive noticed most growers end up using some level of a calmag supplement through their grows. Happy vegetative stage! The over all plant health looks great, nice and bushy.😊
