Nutrition lockout?

If you can't get the ph up maybe a little lime from your local nursery is needed. That being said, recovery time in soils can be up to 2 weeks. If you think you have over fed, that really slows bud production and will affect your girls from flowering as good as they should have. A sign of over feeding is the pistols on the flowers will turn brown/red very early on. Some say this is normal, but it is not. A proper fed or even a little underfed girls pistols will stay vibrant up to 5 weeks after flowering starts. That's normal for a properly fed plant. Browning within the first few weeks and your flowers won't reach the potential that they could have. Cheers
