so lets try this DWC thing agen.

quick update with a pic.
also this other seed poped out just the other day.

half to wate tiull payday to buy some cam-mag.
anyway how do they look now?

DON'T PANIC.

Use 1 to 2 teaspoons per 5 gallons of epson salts. Like for your bath, get it at the drug store maybe super market. It's calcium the plant needs plus a few other minerals. It will hold you over nicely till you get cal-mag plus. Look at some of the sponsers here or do a search closer to you.

Looking better too. sometimes it just a stress on them from something.

When my plants are that young i don't use nutes or if i do i use a seedling one part nute in low amounts.

can you post a pic of your set up ie How far the lights are from the plants/what lights your using.

also how good are your bubbles? if youve using them airstones for a grow before they get blocked up.

If your ph has been 6 or so this whole time it's not that and with rootroit cubes there more then enough nute for a seedling.

I would say the waters not aired enough to keep a seedlings roots misted above the water level and/or the lights too hot on the plants.

good luck

btw if ur using hard tapwater ( sounds like it ) not RO or soft water u souldnt need cal/mag at that young if not at all.

If your using tap water and have not checked it. Remember chlorine has one function. Too kill all organic matter.

Well water can have too many minerals.

Water always need to be checked that is why most hydro'ers go with RO/ Distilled. It is easier to add back than to take away.
