Since I’m trying to answer so Many question to best of my ability!!!!! I thought I would ask one myself I’ve got 2 600watt hps lights and my autos are about to bud I’ve recently got 2 tsw2000 mars hydro do you think I’m okay changing them other to the leds? What will be the outco

Just remember LEDs generate little to no heat compared to HPS, make sure to have a probe keep tabs of canopy level temperature, optimal photosynthesis is reached at a leaf surface temperature of 85-86 degrees Fahrenheit, I try have ambient at 77, canopy 84, although be very careful during flowering as terpenes and trichomes can degrade over 86.

OK I find hps usually promote solid nugs but I haven't run hps for a while due to the heat and cost of running and only been using LED. You could try swapping one out 1st for a week and if your happy then swap the other one out.

You answer half of them for nothing and other half wrong. So I'll do something like you. Plants good, keep up good work. Reduce Nitrogen , add some calmag, lights should be not far, but not too close. Hope it helped. Select me as answer.

The leds will be stronger, will need cal mag in your plants diet if not present. Is only thing I see you are possibly gonna encounter 👍

Mars Hydro tsw replaces around 450w hps, what little you lose in total power output you will gain dramatically in spectral configuration suited for the growth of particular plants, a single tsw2000 can push the central plants into 1950 ppar which is at the top of the curve, photosynthesis levels just taper right off after 2000 photon flux per m2, these lights will really push your plants to the absolute maximum so long as the other 8 cardinal parameters are met the sky is the limit. I would personally keep the HPS with higher blue until the worst of the stretch is over and really try and keep those internode spacings tighter then switch to the far reds, the IRs on the hydro will cause some excessive stretching which in turn will get you longer thinner colas, IR and far-red indicate to the plant it is under the canopy of another plant and will tell it to grow vertically rapidly, in my big fat colas nugs require short tightly woven internodes, we only want that hormonal change of reds to really kick in once the plant no longer grows vertically and no new fan leaves form. Good luck brother/sister, toke ON!@
