PLEASE HELP !!!! young vanilla kush plant leafs turning yellow, white and drying up

[pgshaun]

Hey pot people, my vanilla kush plant is about 3 weeks old from seed and for some reason everything was fine untill like 4 days ago when the bottom set of leaves started turning yellow. I havnt started using any nut yet as they are still quite young "maybe its time to start i really dunno". my temps are always between 60 - 80 depending on time of day and humidity is round 50. what could be wrong i really dont want it to affect the rest of my baby plzz help !!!
Sorry for the bad quality pics had to use my phone cam and its rubbish.

The same thing happened to me. I'd check your ph if you can otherwise just make sure to let the water sit in an open container for a day or so. What soil did you transplant to? I had mine in mg organic mix then switched to ff ocean forest and lowered the ph and my babies are loving it

No it started as the plant got older and its need for nutes has changed ,start feeding veg nutes asap.
