A lot of times the only difference between a veteran grower and a first year grower is a veteran decided they don't have to baby their plants to death.(Besides,they don't have that much time to baby each one of their gazillion plants anyway.
)
Plants are designed to grow with or without the super duper potting soil and the special nutes people overdose their plants with.
Don't fix what isn't broken.
If the plant is green ,leave it alone.
If it gets the dreaded heeby geebies then go on the internet and see what you are probably doing wrong to your plant.
Most of the time it's that the plant is getting loved to death one way or another.
Not always but 99% of the time it's pilot error not something you aren't doing but something you are doing too much of - water,nutes or whatever.
Aphids are easy,MITES suck big time.
A lot of times I see people posting that their other plants are doing great but a couple are doing their best to die.
I'd bet the ones dying are the ones they wanted to grow the most,their favorite variety.
They are getting loved to death in a lot of cases.
