Get some 5-1-1 Fish fertilizer from Home Depot. Grow big's ratio doesn't have enough nitrogen for flowering. Remember the less green leaves the less bud. Even their bloom formula is lacking in nitrogen. I've seen numerous people on forums with the same problem using your nutes. Read what professionals and degreed horticulturists use. You'll find that all the "special" fertilizers and additives are NOT on their lists. Why would the most knowledgeable people on the planet use what they use? Remember these people make their livings growing plants. Try some fertilizer from Walmart if you want better quality, I'm serious. It's a weed, that's all and it neither needs nor wants special potions. Try some Jack's Professional 10-30-20 for flowering. Btw it is not normal to have a bunch of your leaves turning yellow during flower, look at the leaves of other flowering plants. Add nitrogen.

Very nice healthy dark green leaves throughout. Now look at the fertilizer he used. It's nothing special and the ratio is 20-20-20. That fertilizer is cheap and easy to find even Walmart may carry it. It may be part of Peter's fertilizers. It's the same stuff professionals use all over the country. If you know something they don't then you can be a millionaire. Please don't take that the wrong way, I'm only trying to make a point. The people making marijuana specific ferts just want your money.If you want more bud you need all the green leaves you can get because they make the bud. That's science. Yellow leaves don't help.

gbig and the powders have plenty of n for the whole process
