is my plant suffering from some nute deficiency

Hey everyone was hoping i could just get some input on my plant here, i have 2 big bangs growing atm, and i have noticed some of the leaves near the bottom have become brittle and discolored. also they are currently growing in ProMix HP soil and gets a nute feeding of grow tec grow formula every other watering

Any and All advice appreciated :]

pic of the 2 BB's right side has the discoloration while the other none, and for fun heres 2 pics of my auto blue mystic :]

Do you have drainage holes in that bucket?

i do not, however i try not to water it to much to the point where there would be water sitting at the bottom

Have to have drainage.....and those plants look fine considering?

Agreed. Water intox.

Yes. Good looking plants. Get HOLES!

A drill bit is your friend. Dry on top and water in the bottom.
