week old seedling troubles

Hey first time grower my plants are in solo cups of happy frog I have not put any additional nutrients in the soil they were doing good recently one the leaves are yellow and curling up and one the leaves have yellow spots and a burnt looking area on the first round leaves any help or advice would be appreciated the bulbs are 4 4ft f40 t12 plant and aquarium floro lights

The one thats leaning has been fighting he wants to live I'd hate to see her die

There is most likely fertilizer in the soil. Going through the same problems. Drain the hell out of it or transplant into plain soil

Anything with that much bark in it has got to be too acidic. My guess is that you pH is way acidic. -my 2 cents

eather way to much fert in the soil of the soil is way to acidic like if it came from under a pine tree... flush the soil asap but your main problum now is you stunted the growth right out the gate if thy can recoup thy will take atleast a few weeks to show signs that all is well again, iv been down this road my self man tuff stuff but u live and you learn

how is a red stem a sign of cold my plants outside have red stems and thy are nuted up to the nutes but healty and growing and no it douse not get chillie at night also red stems could be a sign of LOCKOUT.

Ok guys I got a ph tester my first test results are looking high in alkaline would you agree ?? To bring up my acid and shit with home ingredients is there a way to do it ??

Vinegar or lemon juice does the trick.
Mix some dolomite of lime and perlite into your Happy Frog before you pot up.
The lime hels stabilise your ph.
GL.

Sweet how much lemon juice should I just mist the soil with a juice/water mix or get the foliage as well

What would a good ratio be lol

Use the vinegar/lemon juice to get the ph of your next watering down.
It will be trial and error so just add a drop or two,then test.
You could do with a ph meter.
