Bad idea?
Will a mars hydro TS1000 be too strong for a 60x60x140cm tent? I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.

Light intensity
My plants have been looking sad for a couple weeks. Tried everything then the other night I turned my light down to 40% giving a DLI of 28 they perked right up with 24 hours. I have now put it up to 60% giving a DLI off 39 will this be ok or should I keep it low. Week 2 flower.

Lighting cycle for VEG stage. Is 24x7 OK?
Hi, Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED Thanks, Mr.STM

Too much light or PH imbalance?
I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent? Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?

Lux Meter and Hydroponics
Who has experience with using LUX meters to position lights in various stages of hydroponic growth. I feel I am giving mine too much light, based on the readings, but don't want to pull them back. Currently 10" from the plants.

Hi guys! What light should I get? The viparspectra xs1000 or the marshydro ts1000? I intend to grow in a 2x2 space. Would the viparspectra be as bright as the marshydro because its more efficient?

LED Kelvin Temp 3000k-6500k
Is there a massive difference in colour temperature/kelvin of LED's if the lumens, PAR, watts, intensity and every other aspect you can think of is the same but its temp/kelvin is lower? I use a 6500k LEDs, may mix in or switch to 3000K for better flowers if its proven to work.
