2 weeks flowering pics - BG

What do you think this problem is? It's now starting to show on all three ladies. I want to get it fixed before it gets out of hand.

I added Peters Super Bloom last week (very diluted) and this week. Are they over nutes? Are they lacking nutes? I'm watering about every other day if not every two days.

Nobody? Is this a potassium def.? I need help....

def looks like nutes burn. Nute burn will start by burning tips of leaves first most of time. I heard of many people using peters blossom bloom but its not the best choice. A little strong but if thats all you got just use it but might take a week or 2 to get used to it.

other than that you got yourself a healthy lookin plant man
