Hi. I have a few Hulk Berries and Medusa F1 auto flowers growing. I used the fox farm happy frog soil amendment mix straight from the bag. It’s my understanding that the nutrients last roughly 5/6 weeks and people prefer to feed bloom nutrients after that period. My question is at what stage of life would I feed an auto flower the bloom nutrients and do you have a brand suggestion for me to purchase ? They are very healthy around day 28 now. I have done one grow without adding any bloom nutrients and it seemed like they wanted more than what they got and expressed some deficiencies. Thank you for all advice on bloom feeding
