Hello everyone! First time grower and first time poster, I have a 10 week old sweet tooth that is not yet done blooming and is starting to get fully yellow leaves all around with some showing brown spots but not all of them. The plant was kept both inside and outside (mostly the latter) and has not been given nutrients. As per the previous comment I assume based on not feeding it and research that it seems to be either Nitrogen or Calcium deficiency. I think the plant is simply cannibalizing itself and I want to give it more energy to grow a little better if I can. I know that it is normal for it to be yellow the last weeks but I am not sure if it is happening too early. I did not buy the FloraNova Bloom suggested on the site but instead the three part Flora GRO, Micro & Bloom Combo because I also want to use it in the future.
Therefore, my questions are:
Can I save the plant?
How much longer would this plant likely take? Is it normal its taking more than 10 weeks?
Is using at least the bloom part of the three part nutrient combo good in order to give the plant more energy? Should I use nothing at all?

Thanks in advance for any tips!
