How do i know whether my lights are too close or i...

Hey there with your lights you want to keep the LED pretty far away from seedlings. Around 36 inches is a good place to start and watch for stretch. If they start getting tall stems then move them a little closer every day until the stretch stops. If your light it too close you will not see any vertical growth and probably burning on the upper leaves. And as far as feeding since you are in soilless you are doing right by feeding now. 1/4 strength usually works great for the first couple of weeks. Dont wait 3 weeks like others are suggesting for soil. And be very careful not to overwater because it will lock out your nutrients and look like deficiencies. Fastbuds lsd and pretty much all their purple strains are know to get sone pretty funky curly mutated growth but dont worry about it. They usually end up with some killer buds. Hope this helps. Good luck with them.

Ok so autoflowers no nutrients for first 3 weeks man and the transplant doesn't have to stunt if done carefully .. the nutrients are low but in soil she don't need them for a while and then when you do add them those levels seem appropriate .. they can recover just fine try not to over water them now and run some plain ph water for the next two waterings then add those nutrients again .. they will recover .I've got 4 fast buds autos under a 309 watt LED set at 21 inches and they are fine if they burn when your hand is under light at seedling levels then they are to close ... You will be fine man they will recover no worries ..
