They like more food with powerful lights.

I’ve used DE 1k hps before this for a while and never had any issues also been running the same line of nutrients since 2015 With almost identical ppm etc and I’ve only had this problem with the 300 watt mars hydro led. But not with the 645 watt luxx led.

I’ll try that out. I’ve been doing that same ratio but for foliar and it’s helped quite a bit

Is the Luxx a bar type light?

Yes both are bar type. Mars has lm301b diode and luxx has lm301H

Is the Mars more potent? Do you have a meter to check?

I had similar issues with the first gen HLG 288 boards I used for veg if I left them for more than 4 weeks under them but as soon as I put them under the 315 CMH lights they would clear right up I almost gave up on LEDs until I got the gen2 board no more mag issues

A lot of what people think are cal mag issues with LEDs are actually humidity vs temp issues. Looking into your vapor pressure deficit.

Disagree I have always kept my VPD in line... I did have to learn one must bump overall room temps up since leds do not heat the leaves etc like hps CMH

Check out lvpd leaf vapor pressure deficit I do not think enough growers pay attention once you get your girls dialed in you will see noticeably happier plants...

buying bulbs all the time full of toxic chemicals and the having to also dispose of them, whilst I am an all organic gardener just seems hypocritical to say the least

Where do you think your electricity comes from?

I'm not ignorant to that fact but try to do what I can. I would love to just grow in the sun but that won't work out here

My plants are doing great now and all I changed was supplementing mag and sulfur with Epsom salt. I didn't do anything concerning changing humidity ot temperature.

True but you talked shit to this dude about bulbs while most likely driving a car, using electricity, taking long showers lol. No one here is better than anyone else. I don't get why you just tried to act like you are better than this person Because you grow organic lol.

I’m not sure when you should change bulbs but when I did use them I went years before I bought new ones. I think it’s more hype really saying they need changed every 6 mo.

Exactly, when I used them I changed them once every year and a half to 2 years. And then I kept the old ones for back up.
