W2.Day.1(12)
Added some of B-52
Watering: 25 ml each 2 hours of day
W2.Day.5(16)
I started trying to direct the overgrown foliage to the place of its intended growth
W2.Day.7(18)
Only today, on the last day of the second week, Jessica is nearly making her way through her first level. It turned out to be more challenging than I had anticipated. It's unfortunate that I damaged one of her sheets. The good news is that, moving forward, there will be more room to maneuver.
I have also begun to notice yellow spots on one of the leaves. After consulting with books, I concluded that this is a deficiency of calcium and magnesium due to an excess of potassium and phosphorus. But where could this overdose have come from? The soil? Unlikely. I decided that it must be due to the small amount of ash that I shake off after smoking.
I like the craftiness ๐! I have made good experiences with Scr.o.G ing and lights under the canopy. Would only add them in flower though, I had added somewhere around 90w at 30 cm distance on a lollipopped plant. No fluff or popcorn buds anywhere to be found.
@MyDearDiary, always a pleasure, but again, itโs mostly about the individuals preferences. I just wanted to highlight to you that from my perspective there should be no issues to start carefully removing old leaves, without worrying that youโll stunt your plant. The more you grow the better youโll be able to read your plants. Seems like the curiosity is there already ;) any other questions, you can always DM me directly, if I can, Iโm always happy to help.
@Salokin, Thank you very much for this article
It seems that in a home setting, it's quite challenging to determine the photosynthetic activity of leaves and identify the moment it decreases. Making such decisions should be based on experience and the age of the plant and its individual leaves. I would be happy to conduct a series of studies.
Is there a university somewhere that studies marijuana growth? ๐
@MyDearDiary, hey growmie, I read this a while back, which was studied on sativa plants and their leaf photosynthesis rate with age
โ Compared with the maximum estimated y-intercept value, Amax and Rd decreased by 50% and 75% after approximately 9 and 28 days (Figure 1 and Figure 2). Similarly, Ls and ฯCO2 decreased by 50% and 75% after approximately 8 and 22 days. Although photosynthetic capacity declined steadily after leaf full expansion, we note that the compensatory metabolic activity of Rd decreased.โ

A wouldnโt deny that a mature leaf has a higher photosynthesis rate, however, as soon as maturity is reached the rate will go down, but also their metabolic consumption.
what is nice colour for your eyes, maybe far away from spectrum plant needs.
What ever cool leds you would use, they still heat up, that will play up with plant, because they touch each other.
output of such strip will make maybe brighter for your eye, but wont bring any countable result. through all strip its 10-15 W maybe, so what it brings ??? plus spectrum ;)))
i thought its one of photo contest attemps, but by your description - you are serious with it.
Hope it will work for you, but by pure math and facts - it should not.
All the Best !
@AsNoriu, The issue of temperature is not a concern for me, as I regularly use an infrared thermometer and make sure everything is within acceptable limits. Besides, the garland doesn't operate throughout the entire light day.
I treat this as a fun experiment.
