Smell is getting much stronger, keeping with current feed schedule. The buds on the smaller plants beginning to stack much more than the taller plants that vegged longer. The buds are extremely frosty with lots of trichomes.
Hey, there friend great work for your 2nd grow. Would you be alright with me offering some advice and tips for your future grows? So just going back through your flower cycle and looking at the info posted these are the pointers I would offer. Cannabis plants love heat and humidity, It is the buds that hate it. 20% is super duper dry which would be good for the last couple of weeks or last week for sure. But normally we want around 50% for early-mid flower and slowly drop it down to 40% by the end of flower. In veg the plants love humidity, We can speed our growth up through the slow seedling phase and early plant phase with some supplemental intake from the leafs. In veg we can do 60% - 70% no problem for the first couple weeks and it will really help the plants get going. Temps in veg of 79-84 MAX and no more than 9 degrees less with lights off are a good rule of thumb. If we allow for more than 10 degrees less with lights off and have too large of temperature fluctuations we make our plants stretch unwantedly. Right now your temps are on the low side for sure which can make our plants grow a little slow. When we are in flower temperature control will play a big part in how our buds develop.
If we grow buds out at too high of temps we get very big and airy buds but they will be prone to foxtail and also have much less cake. Too low of temps we get really dense nugs caked in resin bud lose out on a lot of size. The best of both worlds seems to be at around 75-79 lights on temps in flower. Once our plants finish their vertical growth by weeks 4-6 of flower, Now we can open up our temp gaps to beyond 10 degrees less with lights off. Now the plants have finished growing vertically it will instead signal the plants to send extra energy into the budding process and resin production.
I hope these tips help you out and if you have any questions please do not hesitate to ask I am always willing to help out.
