    DWC: Switching Cal Mag Brands

    Looks like that was a major issue. The other Cal Mag did not get along with the CCH2O nutes and the DWC system. Once I switched back to CCH20 calmag the issues went away.

    Very Small Seeds - Week 7

    Update: I froze most of it for fresh frozen bubble hash however I think I should have just dried it. The smoke on it is still really good and the seeds are not noticeable in flavor. There is zero popping or unpleasant taste/odor. Ashe is clean/gray/white. No harshness. Flavor is there! What a...

    DWC: Switching Cal Mag Brands

    It seems the plants are yellowing. I've tried significantly upping the calmag too. It looks calmag deficient. I'm switching back to the CCH20 cal mag and will report back with the results.

    Pollen Cleanup from Herm Room

    Thank you all for the responses. Pretty much what I had planned on. Side note - Replacing all timers w/ either digital or a Hydro-X system so this never happens again.

I want to start flowering asap on this new crop but I'm worried about the pollen spreading and seeding out the new girls. I'm thinking to give the seeded flower a quick bath when they're...

    Very Small Seeds - Week 7

    Rollitup Fam, I'm in week 7 of flower, 1-2 weeks left. Unfortunately last week I believe a timer didn't function correctly and stayed on all night! Now it appears there are seeds in the buds. What do you think my best option is? Flower for 3-4 more days with the late bloom boosters and pull...
