Yield

What can I do to boost my yield in the flowering stage...?? Im in the third week now wit some shivas... Looking good but the buds seem a little small...hmm. Any aces up that sleeve...??

Buds are only starting to form in week 3.
You can help them with more light, and more carbon. Molasses dissolved in the fertilizer solution at a rate of 1-2 tablespoons (=one 'glob') per gallon will accomplish that.

You're also coming up on time for a p/k bump- Koolbloom, pk 13/14,
Big Bud, open sesame, or a whole bunch of other products that I can't think of right now.

Walk into yer local and ask for a p/k boost for mid-flower- they'll set ya up.

Also, yer @ the critical point for temps- from here till finish ya wanna avoid extremes either way.

But Herself has made the important points- light and C.
