Please Help me Save my Plant

[gropple]

Hi everybody

I will be really grateful if someone can help me identify the problem with my plant

I was expecting this to take another 2-3 weeks to finish but its started losing leaves very quickly, like in a matter of 3-4 days the leaves have started turning yellow and dying off, some pics attached

been very healthy throughout but last one week has been nightmarish with storms and crazy weather and now this baby losing leaves like its on destruct mode

even the buds are feeling without too much life/oil, dryish, otherwise they have so much life/moisture/stickyness

Its basically a hempy bucket, outdoors, i have been feeding general hydroponics 3 part grow.micro.bloom

Also, two mornings out of last three, ive found the bucket toppled over because of the winds, and i noticed that the top layer of the soil (perilite) was missing and some of the roots exposed. ive fixed that now, but could that be the reason?

I'm not sure but looks like a deficiency, due to lock-out maybe? Do you check your pH? What water do you use?

no i dont check the ph, what should i do if its a lockout?
