You could switch to any light cycle you want. Anything under 18 hours is probably going to reduce the yield.
Surprised it's taking so long. Is it Barney's Farm?
I grew their blue mammoth a long time ago and they only took about 11 weeks total
I forgot about this thread!
They finished a while ago, I let them live together. They did nice! Got about 2 ounces total from them!
You can see the smaller one in the back.
I've used light warrior before, but only on the top half of the pot. If I recall there was a ton of perlite in there already so no need to add more. You'll definitely want to add nutrients, probably around the beginning of week 3
Looking good man! Definitely want to keep the lights as close as you can without burning. Use the hand trick as mentioned above and the stretch will be minimized
Pretty much everything I grow is Mephisto :-) they even send freebies with the super soil so I have more seeds than I know what to do with at the moment
I'm sure they start them inside early. I started mine inside in like April those Humboldt guys use hundred gallon grow bags! I can imagine what a monster that would grow
Yes.
I believe if you're using a soilless medium you want to keep the pH similar to a hydro grow which would be around 5.5 or six at the most.
Personally I grow in soil and fluctuate my pH between 5.8 and 6.4
In my experience nutrient burn usually starts at the tips of the leaves. Looks to me like you might have a pH lockout?
How does the new growth on the plant look?
