Ultimately defoliation is predicated by the size of the plant being flowered. you cannot compare ones grow to the others because of the growers ability. size of tent, room, warehouse, ability to grow a successful ending flowering process. Each is his or her own process of finishing a proper finished flower that the grower has created to the best of there ability in there situation. That being said, defoliate at your will!View attachment 849896
Great sourced information. It’s unfortunate that it doesn’t deal with current LEDs, as I have found that growing under them is very different than those mentioned. I have to agree in the past my tomato plants did not do well under 24hr lighting. 5 and 6 also make me question the relationship of the results vs led lighting. But it’s great information. It makes me curious, when I flip my plants start flowering very quickly, the change of lighting is signifigant. I think your suggestion that my lower temps and the continuous lighting in conjunction give me positive results has real validity. I appreciate your post, your sourcing and your opinion.
Very nice - good effort. I guess important here is it has nice structure and presumably there was good space around her to ensure some light to the lower buds. I SOGed for years until I calculated I'd likely get 15 years in prison:) (too many plant numbers.. wiser to go larger and less numbers) I would never even think about defoliating anything (why bother?) in SOG..
Also it is recognised you need higher air temps under LED to achieve the same leaf surface temperature at lower temps under HPS and MH. Basically unused light turns to heat in the leaf tissue. Because LED has a more optimised spectrum for plant growth than MH and HPS a higher percentage of the light is converted to more energy for photosynthesis (= less light becoming heat in the tissue). And yes there are variables - the question though is are there growth benefits under 24-hours of light?
That could also be an Mn deficiency. Mg and Mn deficiency is almost identical and the two are commonly misidentified.
I tend to agree with you. Just covering bases. And yep nutrients are a bit yin and yang and often biotic and abiotic stress creates what looks like nutrient deficiencies or excess.
It's extra fun when you're colorblind.Definitely! It is hard to tell a deficiency from a nutrient antagonization from a lockout.
Thats why i take a lot of notes and try to get to know each plant.

It started out at the bottom and advanced to the top. Other defoliated plants are showing slight MG def at the bottom as well. Stopped advancing with Epsom salts though.Maf deficiency shows first at the bottom leaves.
And if everything is the same but the leaf plucking guess why there may be a deficiency. Mag and npk are mobile nutrients. They use and move around nutrients from the leaves as needed. They are called a source. They can also be a sink where excess nutrients are stored.
Just a thought.
interestingly, different cuttings from different parts of a plant may result in a different plant. not all cuttings are the same. it is often seen in hybrid flowering plants that lower branches may present with different colors then the rest of the hybrid. the lower colors hybrid phenotypes that were used to isolate the final phenotype. but agree a grower can take the same plant and get different resultsYour 2nd sentence nails it, just about any thread you find, there will be strong opposing opinions from legit growers that know what their doing. Tent vs. room vs. warehouse is huge. Many times my buddy and I will take a cutting from the same mother, one of us will do great with a particular strain while the other has horrible results. Our grows a very similar, it's just the little things.
And genetics blow my mind, you would think how different can two different strains of cannabis plants be, but I swear sometimes it's like a frog compared to a hamster.:)
Here's a side-by-side shot of a deficient cola with a healthy cola (different plants).
Just thinking it might be a nitrogen deficiency in combination with magnesium deficiency as well.
From reading alot of threads about 24hr vs 18hr veg, the general consensus was 24 hour light gives you shorter and bushy plants with fast growth. I'm not sure if its what everyone uses but the majority seemed to be using it for years. My last veg was under 18hrs and i had tall stems and were thin. I really want to try the 24hour veg for my next run and hopefully i can manage it. I'm fairly new to growing, and all i have is 1000w MH and HPS. Any advice would be appreciated.the question though is are there growth benefits under 24-hours of light?
