Lot of good answers below can't add onto what their saying. Best Of Luck

Hugely over fed with nitrogen so unfortunately I don't think your buds are ever going to be that big but don't give up. Flush out all those excess nutes, and give them a pk boost with no N.

I agree, too much nitrogen, but the pictures are not very good. Always post clear pictures taken under normal white light when asking for advice. Too much nitrogen will stimulate leaf growth at the expense of flower growth. True nutrient lock out does not occur until the substrate is below 5.5 or above 7.5. In soil, a range of anywhere between 6.2 and 7.2 and your plants will be fine. Try feeding half strength for a while, even for the rest of the grow, as half strength is usually plenty strong enough. If you are not sure, it is always a good idea to ask questions first before doing anything radical, rather than doing something then asking if this was ok. Cheers, Organoman.
