Nutrient issues?

Its normal for some lower shaded leaves to die. can you post a pic of the whole plant with the container its in?

 

i'd make a serious bet that if synthetic growers added an appropriate ratio of humic substances to their soilless mixture, maybe a little lime, and used synthetics that were in the majority of cation (+) formula then they would have a spectacular worry free grow. actually i think that one simple addition of humic variety would end "ph issues" for synthetic cation based nutrients. throw in 1/4 - 1/2 dose recommended label directions for fertilization and i think they're there.

if i had all the bottles i'd surely give a bag of ewc, composted pine bark, and if available a good quality compost a try. soil chemistry is soil chemistry. it's actually most relevant and easier to control with "fertilizer" based grows in peat based soilless mixes than it is to organic style growing.

just saying...it's inexpensive insurance.

 

IMO your plant is way too big for the size pot its in. If you dont want to transplant it (might not even help at this point) you will need to start supplementing with teas (kelp, neem) and botanicals. I would even do a worm castings slurry and apply as a top dress.

Its not so much that the roots are bound its the fact that 3 gallons of soil cannot provide enough nutrients to a plant this size without supplementing with water soluble nutrients.

 

Some people can grow in 3 gallons I've never tried it I was raised around the font of bigger the better I grow in 7 gallon fabric pots inside and a minimum of 15 outside. Fabric pots are a huge improvement from plastic twice the feedings twice the plants
