Please help ID deficiencies

Ph water and no signs of improvement. These 1 gal fab pots are drying out pretty quick. Soil is still cool and a bit damp under the dry surface soil. Im not sure what approach i should go with.

  1. Continue with ph water only since newest growth looks a healthy shade

  2. Get some unsulfured black strap molasses involved.

  3. Mix up some 1:500 vinegar to water and introduce vinegar to unbind carbonates in my tap water

  4. Introduce some aloe or aloe based nute.

  5. LIFTA??
