Also, which bulk is better, Kool Bloom liquid or Cha Ching ?
Kool Bloom is a stand alone bloom nute, it works good. Cha Ching is the 3rd Bloom nute in the fox farms water soluble trio of CHEMICAL NUTES. Open Sesame is #1, Beastie Bloom is #2, Cha Ching is #3. Right now, where I live (southern Oregon) you would be transitioning from Open Sesame to Beastie Bloom. My advice, forget that Fox Farms stuff and go with the Kool Bloom until you get some more growing experience.
There are basically 4 kinds of Cannabis. (Not counting strains here) Indica...Sativa...Ruderalis...Hemp. Sativa has the "mind" high. This will increase the severity of your panic attacks. Indica is more of a "body" high. You'll sit on the couch, watch the Kardashians, and fall asleep. Indicas typically have more CBD's, CBN's, etc. , the "medicinal" effects. Try some indicas...most everything (but not all) with Kush in the name, Northern Lights, Grape LA, Chem Dog, etc are examples of Indicas. Ruderallis is ditch weed, now used in Autoflowers, Hemp is the worlds best choice for paper products, clothing, etc.
Depending on the size of your plants, if using chemical nutes, feed once a week now, and gradually transition to every 4 days over the next month or so. If using organic fertilzer (and Koolbloom is not organic, I believe) you can feed nutes every 4 days. Do it this way. Day 1 nutes, day 2 nothing, day 3 water, day 4 nothing, repeat as necessary.
Good luck in your grows. Most people here will answer your questions seriously unless you ask them to guess your yields.
