Nute lock out

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.

Plants like acidic soil. 6.5. Measure run off ph to get idea where you are. You have way to much nitrogen looks like in picture. Hard to tell, white light is better. Npk ratio is 1-2-3 is flowering. Very light nitrogen. It will actually hinder bud development. Is what I see and advise. Good luck and hope that helps. 🌱🌱🌱

It’s really hard to see what’s going on with the plant with that light on.. even the ones in your diary are tough to tell. Kinda looks like N tox which would track with calcium deficiency as it locks out calcium.. but im speculating for the most part because I can’t see very good in these pics. Id lower EC of feeds going forward and monitor your run off values.. that should give you a good picture of what’s going on. Be careful with FF nutrients, if you’re following their schedule it’s imperative that you are flushing with their flushing agent as often as it tells you to.. I used the fox farm nutes for a while and instead of constant flushes they work great at 1/4-1/3 strength. Hope this helps.

Flushing with neutral pH or mildly acidic water (6.3 -6.8 ph) is typically your best bet so you should be all good there. Now that it's been flushed and you (presumably) saw a healthy amount of runoff, you will want to give them around a week (give or take on how your plant absorbs water) to dry out from being soaked from the flush abs then feeding at half dose, maybe even quarter dose, and doing working back up from there. A product that can also help you deal with nutrient lockout is Recharge. It adds helpful fungi and bacteria to your water (and thus soil) that can clear up lockouts. I highly recommend it personally but it def is not a requirement if money is tight
