sick seedlings

I have 2 yellow pears seedlings in a coco coir grow medium using tetra flora's beginner hydro kit. I had them in a humidity dome since germination. they are under 3 6500k 26watt cfls. in a Mylar lined Tupperware container. they were doing fine until a couple of days ago, when the leaves started to curl up and some had light specks on them. i think i might have aphids but i don't want to misdiagnose the problem so i wonder if any of you can diagnose it for me. sorry that the pics are kinda yellow. thanks hears the link https://s1248.photobucket.com/albums/hh481/hydrogirl35/ i don't know how to post direct pics so i just made a photo bucket.[/img]

with photobucket it is very easy. Just mouse over (put your cursor on) the individual photo. A little square will show up with codes. Just click on the bottom one, the IMG code, which copies it. Then paste it in here (you don't have to use our Img button, that coding is already in what they give you).

It sounded like you were talking about hydroponics, but the picture above is just a couple of (yes very unhealthy) tomato seedlings in a plastic cup sitting on a stove. Did you pull it out of the hydro system for the picture? I know next to nothing about hydro, but I don't believe they would ever have things in cups in the system.

A picture of the system, not just the cups on the stove, might help, since I am having trouble understanding it and understanding what is hydro about it... a lined tupperware with humidity dome.

If aphids were causing that much damage, I think you would be very aware of their presence. I think this is an issue of conditions, water, nutrients, light. You mentioned the coco coir, you didn't mention any nutrients. Coco coir like peat is a sterile, nutrient free growing medium. Plants can't survive without nutrients. Also it sounds like you have plenty of light, but it is outside the humidity dome, which probably filters it. And I don't know about the water issues, since I don't understand what you are doing and what the hydro part of this is. Personally I think humidity domes are only for germinating seeds and are very bad for seedlings to stay under them.

Location the moon, is very cutesy, but doesn't give us any information. If you are anywhere except the latest season areas, I think I would give up on the starting tomatoes from seeds for this year and go buy yourself some well started transplants. Your seedlings look terrible and are not likely to do much in time for this season. We all learn from experience and there is a lot to learn about indoor seed starting, especially if you are trying to do it hydro, which is technique heavy.

I'm in Ohio and my tomatoes have been in the ground for a month and have little tomatoes on them.

i moved them out of the grow box because of the glare. i could only get i good picture on the stove. this is what a humidity dome looks like https://www.bugbitingplants.com/18-potted-bulk-packed-venus-flytraps.php. it keeps the humidity at around 80-90%. as for the type of hydroponics it is coco coir. the coco coir is a type of soil-less grow medium. i am using this https://www.amazon.com/Technaflora-Recipe-Success-Starter-Fertilizer/dp/B0001XGP32 for nutrients. what you do is you mix up a nutrient solution recommended for the stage of growth. you water once every 3 times with your nutriment solution. this prevents salt build ups or nute burn while still giving proper nutrition. it is relatively new. that is a solo cup. it has 8 slits in the bottom for proper drainage. i have them on an 18/6 lighting schedule. the night time temp can get as low as 68F and the day time temp is a steady 73F. it does not mater where i am as this is an indoor grow. oh yea and my co2 level is almost 2% verses the normal 0.0387%. i have grown peppers and tomatoes using this method 6 months ago. my cfls are about 6 inches away from the tomato tops. as for the humidity domes i had some seedlings that dried out because my relative humidity is 45%. once that get bigger i can switch them out. if you must know i am in the ms delta. i don't grow out side because they spay us all the time and my outdoor plants died from that. also when i grew in a green house so they did not die the tomatoes were not sweet because the days were too short. also i will be giving them a micro boost using the compost tea made usinghttp://www.amazon.com/Progress-Earth-Organics-TL1-Tonic/dp/B0057RQDAM/ref=sr_1_9?ie=UTF8&qid=1337809774&sr=8-9. hope this helps . oh yea and my run of is a little high at 6.8 ph.

Then you probably want to be posting your questions in the hydroponics section here, where people that understand this stuff hang out...

i don't think that this is a problem that some of you dirt gardeners have not had at some point. I don't think i t is a hydro problem, because my black krim in the same set up germinate slightly sooner and is healthy. i put this in the tomato section because i thought that you guys would know what it is. if i wanted to talk about hydro i would go the a weed grow four but i don't i want to talk about tomato in specific, because that's what i grow. so if any of you know what is wrong pls tell.

Nonetheless, I am moving this thread to the Hydroponics Forum, where the nutritional solutions will be more readily understood by participants.

The seedling could be suffering from excess heat/burning/scald, lack of nutrition, or any of many other factors. Without seeing it in situ, it's very hard to know where to start in the analysis.

i don't have any nute problems or burning at the canopy it is 73f. it is a fungus compounded with mold.i am putting it in a 50% relative humidity environment with a nearly pure c02 atmosphere. it so far is working they seem to be doing better.i will do this for a week or so. i will sow pics when i think that they are better.
