3 Week old seeds, no nutes have burnt tips? ( pics )

pic 8/8 isnt all burnt, its just really shadowy , its actually realllly healthy , just the tips burnt.

What is that medium they are in? What is the ambient temp in the grow area? What is the watering schedule? What type of lighting do you have? You need to be more specific my friend.

Sorry bk ( ps your a very helpful fellow i see yuo everywhere now ^D^ ) There in a nursery soil they dont have time release nutes, that all i know on them, as to watering they get watered 1-2 times per week. I just wait for them to dry out a good amount. Lighting is really just a bunch of scap. I have a flurecent tube in there, i have an animal light in there ( has alot of the same spectrum but i got it for free ) and i have another bigger red spectrum plant light. 0.o really a gheto setup man, in college just throwing it together best i can.

and i have a ph tester, its 5.8oc.jpgthose are the lights, plenty for low end seedling stages. im getting a 600 watt hps for Christmas so thatll be cleared up then.

the soil they are in does not look too good. where did you get it? i'm thinking there could be some compaction problems. are you able to pot them into larger pots with good soil?

Its not too bad. I can see your leaves are really green. If anything prolly too much nitrogen. do you have any knowledge on the npk of the soil?

he hasn't fed them

burnt tips are indicative of a K deficiency, sometimes a Nitrogen deficiency too.

I think perhaps the issue is heat stress. The 'animal' light is meant to heat, not grow. I would remove it. The issue does not look like nute burn to me. Be careful when you get the 600w seedlings do not require that much light. Wait until they have a few sets of true leaves and have been transplanted into a bigger medium. Also, I would consider changing the soil when you transplant. I use FF Happy Frog. Not too 'hot' and not too low in nutes, just right for a good 3 weeks and then start a nute schedule. For now I think you should get a couple more cfls, loose the critter light and the other one as well. I think this will clear up the issue. Good luck!
