DIY Cheap Noob Indoor Amnesia Haze grow

Day 72. There have been lots and lots of rains in these past days, so the humidity everywhere is high. I decided to cut some of the leaves (as few as possible) that were to close to eachother. I cut only about 10 leaves, but they were all covering budsites and completely touching and folding within eachother. After that I separated the branches a little bit from eachother with a very subtle LST. That fixed the humidity from 70% to 55%✓ Day 73. More intense storms, almost 90% humidity outside, and 70% at the grow tent (I guess because of good airflow and the defoliation I did). I checked the weather and this is supposed to be a very humid week. So I will leave a big fan blowing gently but constantly on it. I guess I prefer to risk some wind stress than to have to deal with pests and diseases... I will also only water 1 Lt of water today, to dry it a little bit. If I see that the fan is not enough to lower the humidity I might cut a few more leaves. I prefer not to cut leaves, cause as a noob they are precious to me. If I screw my nutrients (which will eventually happen to every noob), the leaves will save me, by sacrificing themselves and donating the nutrients they can to my flowers, instead of my flowers directly being affected by my lack of feeding experience. //On adjusting nutrients// Well, on the blueberry cannabis grow that I did before this AH grow I ended up dailing the nutrients to about 1 to 2 mS/cm, but the plant drank less water (was way shorter than this stretchy girl) each day. So for this grow, now that I am watering about 3lts/day, I would decrease my nutrients back to 0.8mS/cm until the plant leaves ask for more, or if the EC on the runoff never increases past 1.4mS/cm. In a nutshell, I believe that although giving more nutrients to your plant would likely help her develop faster and fatter, it is very easy to give too many nutrients. So my advice for other noobs like me is to just give them a little bit at the time, and check EC on runoff for accumulating salts. EC on the runoff is tricky, as some people already kindly informed in the question I asked. However, it seems that it can at least serve as an indication of change, say you have a runoff of about 1 mS/cm for 4 weeks, and next week you read 5.0mS/cm after upping the nutrients, well that could indicate that you are nearing the limit of what plants can uptake on the roots, and the rest is staying as salts in the soil, or that you need to add more water in between your feeds. You name it, is just a "flag", or indication of change, by itself it wont tell you anything, but by observing it during your whole growth cycle, and specially after important changes in feeding/watering it might give you ideas of what is going on in the root zone. TLDR: Noob = feed lightly, its better than burning your plant, and easier to fix (just feed less lightly, as opposed to fixing an overfed plant). Pro= well, you are probably a pro because you have experience and have already payed enough attention to your feeding/watering and their effects on your particular setup, you keep on experimenting and answering questions of noobs like me please!
