So far I'm very satisfied with my plant. I believe I need air circulation in my grow bow would help the leave tips from drying out. Besides that it's been a really easy grow.
I am very happy and excited about this autoflower it is my very first auto flower grow. I got a new light a marshydro 3000 and plan on putting it in my grow cabinet as soon as I can figure out how to deal with the heat until I can afford a exhaust fan.
It seems to have slowed down on its growing and stretching. I don't believe it is gonna get any bigger. The buds are starting to form and I'm excited to see how it goes. Just a few more weeks left.
Seems like a heavy Nitrogen (N) toxicity and a slight Potassium (K) Deficiency - Deep dark foliage with tip chlorosis (burns), and lower foliage suffers from interveinal chlorosis (yellowing from margins inward while venation remains green).
The fertilizer you are using right now might be good for other fruit/vegetable plants but not for cannabis! try getting a flower/bloom fertilizer with a high PK dosage (N-P-K values on the label) for now and in future grows get fertilizer sets designed for cannabis.
In the meantime lower the fertilizing dosage to about 0.6-0.7ml.l and make sure you water with pH balanced water and with at least 20-30% runoff!!
Hope this helps! Good luck and happy growing :)
Not the best picture but at 8 weeks it’s coming to the end of its life cycle, but it looks like it’s re acting to your fertilizer. What are you feeding her and did you get brown burn spots throughout the grow?
Yes, Miracle Grow 15-30-15 is no where near what cannabis needs. Next time buy proper cannabis nutrients, GHE make Flora Nova Grow and Flora Nova Bloom that are really good and also easy to use as they are complete and require only one bottle of each with no mixing with other bottles of supplements. They are also rather concentrated, so one bottle will last multiple grows. 24 hours of light is also not good, 18/6 is far more plant friendly, as believe it or not, but plants actually do need to "sleep" and undertake certain metabolic processes that it can not do during the lights on cycle. At this stage there is not much that can be done to rescue this plant and seeing as she is rather close to harvest, I would be giving her only plain water and giving her some "time out" by reducing the light cycle to 18/6. This may just save her THC quality. If you think about it, 24 hours of light is basically plant "torture". No plant on Earth has ever grown with continuous light, 24 hours a day for weeks/months/years on end. Cannabis can only grow so much in any 24 hour period and for cannabis, this period is 18 hours. After 18 hours you are basically wasting electricity due to the fact that cannabis can only grow so much and remember, they also need to sleep so they can "repair" themselves. Constant light deprives the plant of this "repair" time and is no doubt a contributing factor to why your plant now looks like it does, combined with the inappropriate nutrient you have been using. During flowering cannabis needs something like 2-4-6 and nowhere near the 15-30-15 of Miracle Grow. Things to keep in mind for your next grow! Hope this helps,..... Organoman.
Seems like the Potassium (K) deficiency from the last question got more serious here, plus some signs of Iron (Fe) and Magnesium (Mg) deficiencies - Lower foliage develops tip and margin yellowing and chlorosis (Burn), mid-top foliage with interveinal chlorosis (leaves turn yellow while veins remain green.
This is not normal!! When growing cannabis for yields foliage should remain green throughout the whole cycle!! flushing or leaving leaves to yellow and die will only harm yields and growth time!
Provide your plant with a proper nutrition for the whole grow and you'll see much better results.
Hope this helps! Good luck and happy growing :)
