hi, I just joined the website today in hopes to get some answers on why plants keep dieing, I have a 600w HPS/MH lamp set up thats on 18 hours a day and off 6,
Welcome to the forum. Lets see if we can help? For starters, how far above the little tender plants, do you have that 600watt furnace? If it's closer than 2' you will cook those little babies, its like laying a new born child in the sun for 18 hours, it will probably kill them all by itself.
im growing in mircle gro soil and feeding with mircle gro 24-8-16 plant food,
Well....hmmm.... Garden Knome used Miracle Grow Soil for his plants when he wrote his book,
Marijuana Buds For Less. He didn't add any additional nutes for the entire grow. If you didn't burn them with the light, you probably will succeed with the nutes. They are babies and you are trying to feed them a BigMac. Seedling should not be given any nutes until they are about 2 weeks old, and then you would start with 1/4 of the recommended dose, gradually building to full dose. If you have Miracle Grow Time release, then the nutes are already there, don't add any.
the room is ventilated with a 250 cfm exust fan and a 80 cfm intake fan, i also have a few other stand up fans movin air around and blowing on the plants...the grow room maintains a tempture of about 83 degrees in the room and about 86 to 88 at the plants...
I hate to tell you this but your room ain't ventilatin', if it were you wouldn't have these heat problems. I'm gonna go out on a limb here and guess that you don't think you would need to air cool the furnace separete from the rest of your air handling system. Now that you know that isn't correct get a system for 'air cooling' the light. YOU NEED TO GET YOUR TEMPS DOWN. 78f would be ideal.
i water them about twice a day (whenever the first half inch of topsoil is dry)..
Soo.... first your fry them in the sun, feed them BigMac's and put them in suffocating heat. Just to make sure they don't have a chance you then drown them. Does it rain twice EVERYDAY where you live?
Friend, I think you got some issue's here, as a matter of fact. I think you have all of the issues here.
You have too much light, with too much heat, too much food and too much water. Do you have an idea what the relative humidity is? Kinda like a Sauna in there? THINK SPRING!!! When we get the spring rains everyday nothing starts growing, its when it tapers off that the buds come out, its still pretty cool, 88 degrees is rare, not the norm. And if we have a week of rain, things kinda stop growing, til the sun comes out and the water soaks aways into the ground??
now as for the problem all but one of my orignal 9 seedlings totally stopped growing and started to become yellow and warped looking (with branchs and leaves growing into each other and twisting around) about 3 weeks went by with no change so i removed all but one dark green rapidly growing plant...about a week after the other 8 plants had been removed i noticed that the lower fan leaves of my once healthy dark green plant were begining to turn yellow, they leaves kept getting more yellow and then started getting browins black spots all over those leaves until they fell off this has continued to work its way up killing 2 sets of fan leaves and rapidly working on a third?
Any ideas what i may be doing wrong? this is my first crop and i just bought a second batch of seeds that i would really like to work..
thank you

I have presented a few here, and I am sure right now you would probably like to strangle this old man, the funny thing is, it really sounds like you are trying to get everything right and may have just gotten some bad advice along the way. The twisted plants were trying to tell you to quit drowning them, soil should be watered at most every three days. The roots need oxygen, The way they get it in soil is by getting dry. As gravity pulls the water down to the bottom of the pot, air is pulled down to fill the space the water occupied, yours never gets down to the roots, cause you fill the air space with water. Quit drowning your plants, then we can work on the rest of it.
What you need to do is start a Journal, and share all of the details there. Pictures are a must. A few little tweaks here and there.........VV
