i just transplanted into bigger pots. Added new soil with nuts below 1% each so i added nuts 10-10-10. Plants are 2 weeks. Only the two tiny baby leaves that haven't produced yet have burned or die. Did i put too much nuts. Should i transfer again if i put too much rock nuts?
pics would help, but yes, if you transplanted and gave nutes to your 2 week old seedlings, then yes,you most likely burned them.
You could have damaged the tender roots re potting such a young seedling too.
You can buy a decent 4-way tester for about $35. Will test soil ph, soil moisture level, soil fert level and light level. Go to any hydro shop or order off of Amazon.
