A friend of mine is growing an auto-flower (Northern Lights) and thinks he was set back about a week figuring out the pH was too high. That’s now corrected & the plant is growing again. His question was: will this just mean, for an auto-flower, that it will flower about a week later than it would have otherwise, or does it mean it will flower at it’s “normal” time and he’ll just see a lower yield or such? Or will this go a different direction? Any thoughts from those with knowledge of such things?
That’s a really interesting question @Cornholio
Pinging @Stephen for help on this one. My assumption is that it would still flower at the same time regardless of issues or not; however, this could require some science experimentation to prove this theory
My theory is that the plant does not have a watch or calendar, so it’s set (as opposed to photo-period) flowering stage is probably triggered by reaching a certain stage of growth, which will occur later in this case where growth was retarded for a week or so. But that is just me trying to reason through this, not based on any expertise.
Autos do have an ‘internal clock’ that triggers them to flower. Most basically start flowering after 2-4 weeks of growth. That being said, with all of the genetic mixing of Ruderallis with sativa/indica, you will see some reacting differently than others. There are many different types of Auto Northern Lights genetics out there from several different breeders. I will sometimes see a difference of several days when pulling ripe flowers down from the same strain too. So to distil my ramblings,
Stress can delay an auto from auto-ing.
