That’s a good question, I’ll be honest and I haven’t done this so I dont exactly know but I’ll share my thoughts.
Switching from a weaker light to a stronger light will of course change the consistency of the growth but there are a couple variables to consider.
First how much time/ growth of the bud was under weaker light vs stronger light.
Secondly what’s the difference in DLI (strength) between the two lights.
It will all effect yeild as a whole but I don’t think it would make for a airey inside and hard outside if that’s what your thinking, and if your thinking that then I would ask why?
HPS is the old school standard but to say it’s better than LED’s is actually a false statement. Again there are variables to this statement, it depends on the type of LED’s and the Wattage.
Studies have actually been done and LED’s produce better bud then HPS, higher yeild and more cabinoid percentage including thc.
You can search out the study on google if you wish, it was a controlled study with a paper written (so not some back yard forum member running a test)
The issue is your running sub par LED’s, they are okay but not in range to compete with HPS.
LED’s cost more up front but quality ones don’t even use fans, produce much much less heat and thus are more efficient, safer, lower operating costs, have better light penetration, can be run seed to harvest with much better results then HPS (normally you switch to MH or CMH for veg), and ultimately better cabinoid percentage.
I hope this reply was helpful
