Hello fellow growers!

1st time grower. Recently germinated 3 seeds (8 ball kush- Barnys), all sprouted no problems. Issue i am having now is that it seems 2 of the 3 plants are developing yellow burnt edges (dry edges) and black spots.
All seedlings have been in jiffy pucks now for 2 weeks (one of them i have potted in miraclegro potting soil-i know its not good but looking to get organic stuff this weekend), i dont think its a nutrient deficiency as its only been two weeks in the puck.

Also i have read somewhere that the leaves should be dark green if they are pale it means they require nutrients.
I belive my leaves are pale...

Here are some pics. Pic #4 is the good plant.
(also does anyone know if its bad to keep house plants and marijuana plants in the same tent?)

Thanks in advance

Bro you are going to keep running into problems using MG. I used that stuff once and will NEVER use it again. The slow release chem ferts will fuck with your ladies badly. Whats your temps and ph?
 
Hi Lord MEgatron thanks for the reply.
Temps range from 81-86. Humidity around 30% RH. Not sure what the PH is of the lady in miracle gro, i am switching soils this weekend and going to test it then.
Im not sure if its the miraclegro thats ffing up my plants as there is 2 seedling that i havnt potted yet and one of them still shows sign of yellow/burnt tips. The tips are drying out and crumbling.
 
Get your temps to 78-80 thats even better. Also I can tell you now its the MG thats fu$%ing with your ladies. MG has time release ferts so everytime you water it slowly release chemical nutes. I learned that the hard way my last MG grow. If you do use MG use the Organic kind and add Dolomite lime. Oh and get your RH up some you can do that by filling up some bowls with water and sitting them around your grow area.
