I decided to get into gardening this year for the first time. I planted a veggie garden, then a friend gave me 3 cannabis seedlings he had started from some random seeds he had saved over the years. Having no clue, I went online and got some basic info on pot size, soil, etc. My plan was to just let them grow and see what happened. 2 of the plants turned out to be males so I discarded them, leaving 1lone plant that I have become obsessed with keeping healthy and hopefully harvesting. I planted the seedling outside on June 1st. It has continued to grow (in height) quite well. It has always been sort of a light green colour but over the past 3 weeks the leaves have become paler, tiny yellow spots appeared on older leaves and a few larger fan leaves turned quite yellow. I tested the soil. PH was a bit high so I added PH Down and started feeding with a bone and blood meal additive. I wondered if it was root bound so I transplanted it into a slightly bigger pot 2 wks ago. It has continued to grow but the spots on the leaves have not improved. I took my soil samples to a store that specializes in cannabis growing. He said the PH seemed fine, nitrogen appeared low. He gave me FloraNova Bloom (4-8-7), said to feed once or twice a week. I am now wondering if there is something else I need to do or if I should just leave it alone and let it grow? Any suggestions?
