They were just fed thats why they are wet like that. I had them under a 400 watt hps for first week but now they are under 125 watts flouro 6500k. The PH is regulated through my nutrient "perfect ph" wich makes my solution about 5.8 on the money, as for the soil, i dunno. Temp is about 75 with great ventalation. I water when they are dry as a cork and pull from the sides of the cup and i feed every other watering or when they turn yellowish. Picture doesnt show , but they have weird blotches of yellow and green.i thnk ppl are gonna need a little more info to answer your question. ph, temp, feeding lvl, how often are you feeding/watering, is the soil always that wet, are there holes in the bottom of those cups, ventilation, lighting, what soil are you using... more info the better
in the photo they look a little underfed to me. the soil looks a little wet. so my guess would be overwatering/root issues, but honestly, i don't have any info to go off of except a pic.
I have a light feeding chart that has a diluted seedling mix or for clones. I never fed them until they turned yellow. this is actually their first feed.First you don't need to feed seedlings!
Light and water is all they need at that point.
Not sure what you want addressed,
What is the issue you are having?
They started turning yellow so i hit them up with a light advanced nutrients grow micro bloom under the seedling directions, should i mix lighter strength for soil???????It looks like discoloration by nutes. Its true, they don't need any yet, especially if the soil has some already in.
