Hi im brand new to growing forums and some sound advise would be much appreciated
not really a serious grower but like to have a bash at it like abit of a hobby if u like lol. Anyways the autoflower is in about week 5 or 6 and have been feeding 1ml bio bizz grow every other watering for the past couple of weeks. Everything was going smoothly until all of a sudden the plant doubled in size in literally a week and the flower hairs are quite prominent now. The past couple of days ive noticed that mainly the new top half of the plant is yellowing and has a few very small brown patches on the leaves. Should I have switched to bloom by now is tht the cause of the yellowing bcuz the plants nicking energy from the leaves to grow the bud I gave no idea. I need to rid the yellow somehow and start on the bloom cuz the primary fan leaves are nearlly dead to so might b time to switch. Its only growing under a 125w cfl on my bedroom draw lol. And I havent phd the water because the hydro shop bloke told me the soil should buffer the ph. Bio bizz nutes and plagron royalty mix are being used cheers. Happy toking
