Hey dudes, I've got yellowing of my lower fan leaves during week 2 of flowering. They are easy to pull off. My soil pH is 7.2ish The pH of my feed is 6.1ish. It's an organic grow so from what I'm reading I can add lemon juice, but I'm not sure how much since the feed is already skewing acidic. They are also drinking a lot less than they were during veg, from 1l per day to 1l per 1.5-2 days (18h on/6 off light during veg to 12/12 light during flower)

2) Growing - Indoors
3) Watering schedule - 2l every 3-4 days, organic biobizz nutes (1 ml/l grow, 2ml/l bloom, 1ml/l top max this week)
4) Growing Medium - All mix soil
5) What stage of growth - Day 12 of flowering (after 8 weeks of veg)

Thanks for your time dudes.
