Hey everyone, first time ever growing and I'm doing something wrong. I'm using pro mix medium as soil and starting in Dixie cups, under four T5's. They were doing great until I switched to my G8LED 600 Watt. They are 7 days old now and starting to have yellow spots . I almost think they are burning. Humidity is at 50% and temp at 77. I have the light 50 inches from the canopy and all hell is breaking lose . This is the second time this has happened now. G8LED says I have the distance right so my question is, is this a light issue or nutrient? I'm lost and about to say screw it . I've lost hundreds of $$$$ on seeds now .

Stop making multiple threads. Your plants are in mud. Get a soil that doesn't hold that much water. I see permits, but not nearly enough of it.

So in short, medium is to dense. Without knowing more detail.

What is the medium? Add anything?
 
Sorry about making that many threads. It said they weren't posting . All I have the plants in are the Promix medium. Not adding anything . Watering them when it feels a little dry

Without pictures we can't be sure. To me it sounds like the issue is happening when you switch over your lights. Switching to another spectrum so early could be shocking your babies a bit. Are you using any fertilizer or are you letting them feed off the soil?

Wait for it to get dry. Not kinda dry but dry and light. You shouldn't feel weight when it's dry. The pots will get really light.

I haven't used promix, but when I see people using it, I'm pretty sure they cut with perlite. I will still say that the roots are prolly oxygen deprived. You have to let the pots dry out. Cannabis likes dry/wet cycles in soil.

I had problems with getting the right type of soil, I'm moved to dwc.

Cannabis likes a "loom" type soil.

Just Google or search soil consistency of cannabis.
 
Ok will do. The first time I tried this I had a mix of black gold soil mix and the medium and the same thing happened when I switched lights . That's what really o corned me . But I'm gonna do a little research on the consistency now. Thanks for the help !
 
Sorry I thought pic was up. The first try I used black gold soil and the second time I used just pro mix. Both were doing great until I switched lights . I put the first ones back under the T5 and they rebounded after I cut off all the damage. The new ones were doing awesome and then they just started doing the exact same thing the first ones did when I switched the lights. If the lights are the problem, when should I switch them from the T5 to a bigger light ? Another person said it sounds like oxygen deficiency.

The medium is too hot for seedlings. When you put them under the big light they stress because they're not healthy. Change to a mix like coco , perlite and peat and then you control the feeding not the medium. The reason the soil wont dry is because of the health of the plant, sick plants dont drink much if at all.
Coco-60%, perlite- 30%, peat/ sphagnum moss-10%, dont feed for the first few weeks.
 
Thanks everyone . I'm trying not to get frustrated but spending all this money and killing them is not cool ! I have black gold organic soil and a shitload of perlite. My water PH is 6.0 and transplanted them today. Put them back under the four bulb jump star light . Hopefully they start recovering.
 
I'm thinking over watering.. 600's ain't shit... I've got seedlings closer than 50" on 1k watt lights.. Your pictures suck .. Do you have drainage holes in cups? A fan to circulate air and speed up the drying out of soil?
 
Damn those pics do suck. Doing all of this from a cell phone . No internet where I live but on cell phones. I have a two inch fan in the grow tent, holes in the solo cups. The leaves started curling up and looks like rust spots. I was using just Promix BX. Nothing else. They were growing fine until I put them under the LED, same as first attempt. Now I have them in soil. Been watering them when they feel dry or the cup isn't feeling heavy as usual.
 
That's good.. I use as much rain water as possible. I still think you are over watering .. Its about the only thing you can do at this stage to fuck them up.. Let em get real dry before ya water em.
 
that promix bx is meant to hold lots of water meant for outdoors, u need promixhp or add perlite to the bx bx is loaded with vermiculite to hold water promix is great stuff once u no how to use
