Hey Buddy, breathe for a second, this is not a disaster, and absolutely not a reason to kill your plants.
A 5-hour light delay feels scary when it happens, but in reality it’s a very common mistake, even for experienced growers. Plants don’t think in single events, they respond to patterns over time.
What I’d do if this were my grow:
• Turn the light back on and return to your normal schedule
• Don’t try to “correct” it by extending or shortening the next cycle
• Don’t feed extra, don’t flush, don’t prune
• Just give them stability and calm conditions
One missed or late light cycle causes far less stress than panicking and making multiple changes afterward.
Plants are surprisingly resilient. They deal with:
• cloudy days outdoors
• storms
• uneven light naturally
A single 5-hour delay won’t suddenly ruin them.
What matters now is:
• consistent light timing going forward
• stable temps and airflow
• leaving them alone to recover
Watch them over the next few days. If anything shows up later (and often nothing does), it will be subtle, not instant.
So no, don’t kill them.
This is a “learn, reset, continue” moment, not a failure.
And hey… we’ve all done something like this at least once. You’re not alone .
Growers Love my friend, keep us posted and please remember this is just my humble opinion
