Drip system

Noob here, I started some seedlings and they are all reacting differently. I have some that the stalks are shrinking to nothing and the plant falls over and dies. I have others that are getting yellow spots in the middle of the leaves, and other ones that are just not growing much at all and have stalks dark red in color. I am using BC Grow and the PPM is at 600 and the ph is right on. Can anyone give me some advice to what is going on.

Sounds like you are trying to introduce too much nutrition to the seedlings. That could be the main source of the problem. I don't start giving food until the root system has been well established. The same is true for clones & seedlings.

So I should be giving them plain water until they have established a root system

i would. or cut down.

I am reducing the solution strength now to 150ppm or so. I hate to waste all that water. Do you think this will be OK? Next time around I will only use plain DI water. Thank you for the help. Is there a comfortable strength for clones and seedlings?

I have read more on this and it seems that it is a result of an Fe(iron) defieciency. Has anyone ever had this problem with seedlings? My ppm is at 130(BC Grow) and ph is at 6.0. By now the seedlings are probably in shock, how long will it last. Grow room cliamate is 54% Humidity and 74 degress F. I would imagine that the room falls to around 67 degrees when lights are off.

My problem is watering, I think? Is this possible? These cubes are just getting too wet. Can anyone point me in the right direction to read more on this?

you are either over or underwatering, or its a nute problem

Yes, I think it is both, so I am only running DI-PH Balanced water. I need to know how moist/wet the cubes should be so that I can better time the drip. I am thinking I need to cut back watering to once every other day or so. I also think that the low temps at night may not be good for the seedlings, so I am trying to find a heating alternative to electric heaters. I am thinking a Heating pad under the flood tray where the seedlings sit or maybe changing the light cycle so that the lights run at night when it's coolest. Any thoughts on heating.

Well no help around here. These forums are not worth shit. People claim to know and know nothing. It is a fend for yourself, because I am not telling you shit, kind of forum! For everyone who knows nothing. I was over watering, too many nutes too early, and not enough humidity in the room. These are typical problems crossed by people learning to grow. That tells me that no one on this site knows shit because not one person could explain why these problems were arising. Thank you to those who have tried and have given me some direction to go research!
