A solo cup grow? :wink: No nutes No nutes! Is that coco, you could but nah let them go. PH your water, are you using distilled for sprouting and seedlings? Welcome to :thinking: here.

should the leaves be dropping does this mean anything

Everything looks normal for now. Might wanna bring the lights up a few inches to prevent clawing.

Your seedlings look great ! It is normal for the new growth to be a little lighter color of green.


One more real serious question what should I do with lights i have 1000w led full spectrum kingled grow light…
Ok so my question is a couple…how many hours do I keep my lights on my seedlings ?and for how many days do they have to stay in the 36w germ light led? also…because I e been running 24 hour lights since they popped…

I wish I had an awesome answer for those questions. My old days inside all we had was regular photo period plants. If you varied from a regular increase in the amount of hours onward plants did ok, not so ok if they were just stuck to a regular on/off cycle. This was the case for me. I had a timer with 10 minute increments so I could get real close to following the natural light cycle.

But, these autos…I can’t say. I’m in 12/12, with a half hour of blurple at the beginning and end so 11 hours of full on full spectrum right now. I am still getting new pistols on less mature and even on the most mature and I’m in week 10. I started with 18 on bumped up to 20 when the flowering started, dropped back to 18 at week 8 when everything was flowering, and then the new schedule week 9.

18 on 6 off for all seedlings. Photo period or autos.
24-36 inches from light. That 1000w can burn so just check up daily if not every few hours. I use humidity domes too :+1:t5::grin:

Was wondering is this supposed to happen at 3 weeks my bottom leaves are already yellowish the top looks like its starting to get yellow

You’ve transplanted to a larger pot, it’s a bit shocked, perhaps the nutrients are kicking in. I’d leave it alone, it almost looks like you can see it growing and filling out.
