Indoor Project Green Thumb

I suggest getting one of these, or something better if you afford it.
I have one similar and it's amazing to see where the light is actually brightest; I have found with HPS bulbs it usually shines brighter on one side....?

Peace, beware if you do buy one as you will be constantly tweaking light position/height...


I have to thank you again. I love my LUX meter. To me it is a PRIMARY tool for a project.
 
HELP!!! In correct file....sorry if some of you read this when I crossed swords, forgot this issue should be in my journal:

I am approaching the fourth quarter. This is another area I am stressing about. "Not knowing exactly when to start straight water and when to switch to late-flower nutriments?"

I understand plain water for the last two weeks. What I don't know is what triggers you to start the plain water? Do you guess when your trichomes are going to be 50/50 (my new Carson Dig. microscope arrived yesterday)? I guessing most estimated flower/harvest times are useless unless you know the seed; these numbers cannot be estimated without static growing environments. The breeders also vary in their interpretation of harvest time.

Reeling back, I am also at a loss as to when to switch nutrients; mid-flower to late-flower? And, when to go from late-flower to ripen? My initial plan was to follow GH chart, but each plant was maturing differently and I found my self following the plant and not the chart. I reckon I should have just stuck to the chart?

04/23/16

Changed nute ratio to late flower:

  • Green-o-Matic
  • Six Shooter #1
  • Six Shooter #2
  • Big low
Changed nute ration to finish:
  • Tutankhamon
I fear I may have changed schedule too early. Signs of various decencies.

Most plants did not seem to like using straight RO for 4th regular feeding and reacted poorly.

Looking at the pistils, most appear white, I think your buds still have another 3 weeks to go, and maybe more depending what you want in the end from these strains.

Natural light pics would help assess the overall state of the plants, it's hard to see in sodium light. :peace:
