Just make sure you're not over watering. How close are your lights from the canopy? Be sure to get them as close as possible.I don't believe it is a water/soil/or food issue.
I was thinking that as well, but don't you think those lights are a bit high cali?no...they are going through a slight shock from the power outage and also now they are introduced to some dark time every night which they didnt used to have...they are just adapting to the environment....give them a couple days and they will be great
I'll helphey i need help trimming...my hands hurt..
Ah, well you know better. I learn every daynaw.....they are too young to have 4000 watts pounding them...give them time they are like 2 weeks old.....and if you look at the plants in the pictures you can see that they are not really stretching at all...just enough to get new nodes.....hps light is tricky..usually what you think would work better using common sense doesn't and the opposite does...at this point in the grow it is almost impossible to fook the plants up..just keep them alive and healthy..once you start to flower is when you have to keep a better eye on things and inspect each individual plant. But he is doing better then most and the plants he is using are fairly resilient anyways..
lift a couple of your pots. are they heavy? let them dry out until they are light. very light. after a few waterings and drying outs you will get a feel for how wet the soil is just by lifting your pots. lift them a couple times a day until you get the feel. it works.
