Should I use LST at this point if pistils are forming? Worried it's too small currently.

Officially entering Week 4 (Day 22) and the Acapulco Gold has started showing her first pre-flower pistils! She is currently sitting at about 5 inches tall with a very compact, tight node structure. ​We had a brief hurdle at the end of Week 3 with a temporary nutrient spike and some dry air pushing the VPD up into the 1.6 kPa range, which likely triggered the early pre-flower response. However, the automated environment is now completely locked in. I dialed the exhaust fans back to allow the internal humidity to rise to ~61%, bringing the VPD down to a perfect 1.14 kPa. ​The 9-gallon reservoir is highly stable. EC is holding steady around 1.12 with an RO float valve handling top-offs, and the water temp is chilling nicely at 67.8°F to keep dissolved oxygen high. I am using a biological inoculant (Monterey Complete Disease Control) in the root zone, so Athena Cleanse has been omitted from the feed schedule to protect the live bacteria. ​I’ve capped the overhead lights at Level 5 to prevent light stress and actively encourage the main stalk to reach upward. Now that the taproots have officially dropped out of the net pot and into the main reservoir, an air gap has been established. No LST planned for this run to protect the main stem; just letting her grow naturally and waiting for the famous Sativa stretch to kick into high gear over the next two weeks.
