Bottom Leaves Falling Off, Please Help

[johnnyrocketfuel]

Please help with my plants, they have gotten sick on me about 5 days ago.

The leaves are turning brown from the bottom up, 2 of my plants have lost the first and second set of leaves (from the bottom up). I did some research and thought I was low on P, so I gave them some epson salt and a little bone meal to bump the P. This is the only nuts I have given the plants for they are only 18 days old.

Here are some specifics:

Soil: 1/2 Scotts Potting Soil .08 .12.08 Nut Levels, 1/4 Perlite, 1/4 Sand
Age: 18 Days Old
Light: 400 Watt MH Light On 18/6 Cycle and about 18" above plant Tops
Light: 2 - 80 Watt Flour. Light Fixtures (2x40 4 Foot Long) 18/6 Also
Fans: 2 Fans One On Them, Other Oscolating to move are around
Nuts: No nuts until bone meal and epson salt to boost P

I gave them the bone meal and epson salt about 3 days ago and it has not helped yet. The leave stems are a little purple, not sure if it is the strain or nut problem.

Any help is appricated, please only give help if you are familiar with this problem. Thanks

This is overwatering. Let them dry and no nutes !

i think that you are using wrong type of nutrients
actually you should not be using any nutrients for the first monthof its life....the light that you have is good...i don't know about the soil mixture but if its well aerated and drain well then you should be fine...also it is evident that is being overwatered propably because of your excessive love to it....
use nutrients with NPK levels in which N >P<K during vegetation (but again it's not really needed, the soil is usually rich enough for a month) and change that into N<P~K when into flowering....

This is only my 4th grow, so I am still pretty new to this, how can you be sure it is overwatering? Most of the plant is pretty green, and very purky. Please explain why you think so.

Thanks

How do you know it is overwatering, if that is all that is great, however I only water about every 5 days and I wait until the top 1-2" of soil is completely dry. Also, I know you should use nutz until past 3-4 weeks, however I just gave it a little bone meal to boost the p, because that is what I thought was the problem from reading overgrow.coms faq section. Please explain why you are thinking overwater.

Thank you for the help.

mix a little nutrient solution, 1/4 to 1/2 strenghth.
i myself would flush with ph balanced plain water first, and make sure there`s good drainage, then add the nutrient solution.
purple stems tell me it`s lacking phosforous

You do realize everytime you flush with that soil, you will release jsut more and more nutirents?

The time released shit is designed to do just sort of a thing, and MJ grow is far too short to handle this type of soil no matter how often you might flush.

Flushing, in my opinion would only accelerate the death of this plant.

looks like fert burn to me too...if they were mine i'd transplant them asap into well draining pots using standard potting soil mixed with cactus soil at 3:1 and put that pre-ferted soil into the rose garden well away from any seedlings...

actually more or less you should be watering every 3 days or so
the soil mix should drain well enough, it should not hold excess water...if it does then the roots will suffocate as they are not able to breath....
you did well to go on overgrow and search for your plant but from what i know the plant does not need to fertilised for a full month into vegetation, well not before you see signs of yellowing at the first two leaves at the bottom of it...
also, i am thinking that a normal cannabis plant grown in soil with the characteristics i've set above should show deficiency on Nitrogen and not in Phosphorous....this probably suggests that there is definately something wrong with your soil mixture....
i am not an expert you know, this is my second grow, you've grown more bud than i have but i would suggest that you start over forgeting all those fancy combinations of different types of soil etc....
if i were you i would just buy normal branded top quality soil for normal flowering plants....at least this way i would have my mind safe knowing that my plants are into soil that has everything needed for a month..
i did my first grow in soil using top quality soil for flowering plants like ie geranium....usually these types of soil they contain already small proportions of perlite or other type of small rocks, for aeariation, and they contain organic materia in them, they come pH balanced, they even state humidity levels and some of them if not all are enriched with NPK and state the NPK percentages as well
