Guys I really need your help I have 10 day seedlings that are yellowing at the tips and curling up. This is my 5th grow and suprising never had this problem starting seedlings.. I am not using any nutrients whatsoever. The temp was around 85, humidity at 55%. Lights were t5 ho 4 ft 6 bulb about 8 inches away. ( this light does get hot contrary to popular belief, you cannot rest your hand on the bulbs or you will get burned) I also watered them twice a day since sprouting. I strongly believe this light has been burning my plant. Since then I've moved it to a 600 hps turned down to 50% about 3 feet away. The new growth is coming on very slow. Please guys give me some advice. Will she pull through and continue to grow. Or will it stay stunted.

Have you added nutes? It may be that as well. And yes, if you have solved the issue, it could survive and lead a healthy and productive life! Dont give up on her yet. I just had some issues with my seedlings and they are coming along nicely. I did panic though and germed 6 more. Now I building another tray lol.

Simply not true. Plants always want the right amount of nutrients.

If it's soil, the soil should be built rich in nutrients from the start. If it's hydroponics, you should start feeding at a conservative, but not too low, vegging ppm right off the bat. Between 1.0 and 1.4EC is safe.

There is never a time when growing plants where starving them is a good idea.

That was always a mystery to me because everyone says the seedling has enough food within itself to survive for 1 to 2 weeks..I just mixed up 2ml/gal of sensi A &B, seakelp and ph to 5.7. I will be feeding this next watering.

What's 1.4 ec in ppm?

I'm not saying your wrong but many people would disagree. I believe I have read many times the the embryonic leaves provide all necessary energy for the first weeks of life. Again not disputing what your saying but just thats its controversial to say the least.

They can disagree all they want. :)

It's not an opinion, it's a fact. A plant starved of nutrients as a seedling will be developmentally disabled whether you think it has "2 weeks of food and thus doesn't need any" or not.

What's controversial is that people are growing without soil in the first place.

Does it really sound controversial that someone is reporting "no nute burn" when they use adequate levels of nutrients at all times? What's so scary about having 1.0-1.4EC? It works, and it works better.

Starving your seedlings for 2 weeks is superstition. I still can't figure out why so many people do it. Why would anything burn at 1.0-1.4EC? Does nature adjust the strength of soil based on seedling age?

Actually, nature does the opposite! When a seedling starts in nature, the soil is MORE fertile than after the plant is mature and has depleted all the nutrients in the soil.

If you're growing with soil, the soil should be packed with nutritional value from the beginning. The soil should be "built" with tons of nutrients, meant to last much of the grow.

The original "don't feed in the first 2 weeks" advice given to noobs long ago was for soil. The reasoning was not that the plant has 2 weeks of nutrients stored in its cots. That just sounds dumb... so a baby has nutrients stored up, don't give it more until exactly 2 weeks? Really think about that. The reason the advice to not feed early is given is so people don't overfeed in soil. The soil already has plenty of nutes.

If you're in hydro, you need to feed on day 1.

Well guys it looks like they pulled through except one. I backed off the water and that seemed to do the trick. I also am feeding them nutrients now since I'm in hydro. Check them out now whoop whoop
