What is wrong? Help!

Private reserve about 3 weeks old now and have not shown much of growth. Some leaves twisting. Been watering with about a ppm of 400 with general organics. Temp in between 72-80. Humidity 45-55%.
?????? They look terrible what to do?

more info is helpful. how often watering, nute strength, possible issues watering to often and maybe nutes to strong for young plants

Check your ph to make sure it isn't too high, something is locking out your phosphorous (purple stems) and nitrogen (light green leaves). You have a little bit of clawing so they don't seem underfed. A little over watered. I think there is something about your soil or water they really don't like.

Many nutrient overload/toxicity - flush for at least two weeks -plant shows sign of many element over-use - not prpblem plant young enought to recover which will take about 2 weeks -re-adjust amounts and feeding

looks over watered. Transplant into larger pots. Add nutes. , worm castings, compost.

for me seeds in cups no more than 2 weeks. Clones in cups no more than a week.

I had some marrionberry kush seeds that were small and looking horrible no matter what I did. I didn't realize how fast the roots grew. In 10 days in cups they were rootbound. A few days after transplant they were happy and leaves were praying.
