Curled edges

[havesum2]

These are some plants about 3 weeks from seed.
What is causing this?
I have really slow veg growth.
I have curly tips and some have the spots you see.






Thanks in advance.

Get some cal-mag in there and bump up your ppm's.

Mine have that similar spotting as your lower set do then they dry up. Im going nuts as im not doing anything dif I did before. I would think happy frog soil im using has magnesium-calcium. I can throw a plant int the forest and never get it anything and it does better. Im sure random forest soil doesnt have load of micronutrients. Im about to scrap my project, something is killing my girls

def pH.
drop it to 5.8
if this has gone on more than 4 days
the plants are going to turn sour on you very fast.
damage is being done as we type.
leaves will yellow up real fast and burn out.

this is not cal mag

Hey bro, ive read about 30 pages on the root aphid thread. I know its not Gnats but it could be one of those soil pests.Heres the thing Ive taken plants out and inspected closely the roots inside of the quart pots and seen NO MOVEMENT no little black critters or those "red butt" or the white ones. Alot of the symptoms the first guy explained in his thread sound like mine but I see nothing! I am going to get am IMDA asap to see if that corrects it. My roots are snow white and healthy. Ill get some pics up for you to view soon. Its hard to see the plants healthy and an 3-4 days they are looking alot worse shape. things were going smoothly but if this doesnt work all my equipment, nutes, seeds RISK etc are going to be a complete bust. This never used to happen. I was hoping to see some bugs moving around so id at least have some sort of direction :/
