Purple woody stalks under New leds lights

sourdieselyumyum · Jul 17, 2019

I ordered some new led lights from meijiu Shenzhen led light company basically they are hlg 550 v2 spec 3000k knock off. They were being vegged under 1000 watt mh 6500 k spectrum. They are being fed jacks 321 in coco coir 3 gal pots temps are right around 77-81. Not sure if plants are just eating more food or if they are getting locked out by something. Any ideas?

They probably are more hungry. Make sure you stay up on magnesium. Since going to led's more plants than not show purple petioles ime, it's not a def, it's an expression. You'll know when the mag def hits under led.

Same difference in the expression. Some plants on the main, some both stems and main. Go ahead and put up some pics.

Maybe ph is outta wack but shouldn’t be

Those plants need more N, Mg, and calcium def probably isn't too far off. So you switched up to led's, which is going to eat up more Mg. And you're in coco, which eats up even Mg. They're hungry man, boost your jacks a little and add 1 gram per gallon epsom salts or 2ml calmag per. That'll get you pointed in the right direction, you may need to fine tune a lil after you see how they do. I'm also going to suggest you mix 50/50 coco/perlite next time too. Faster feed cycles allow for faster growth, you can really get em growing at 2-3 feeds a day.

yea they are in pure cyco coco I usually water them ever 3 or 4 days when dry I've been doing 3 grams jacks 2 grams cal nit 1 gram epsom

I would double triple check you pH meter just to be sure. If it's good, up your feed. I'm not familiar with feeding Jack's, so I don't know what 3 grams is. What's your ppm/ec? PH?
