Hey, friend congratulations on getting into cannabis growing. These plants are looking very good & I just checked back through your diary and thought I could offer some pointers. Would you be alright with me offering you some generalized advice just in case this may help you? So cannabis plants LOVE heat and humidity. The buds HATE it, In veg, we can exploit this for much more healthy, Vigorous growth. when our plants are small in the seedling stage & early veg, So are their roots. We can help supplement the roots by having some humidity in the environment for our leafs to do some foliar intake with. In veg temperatures of 79-84 MAX are great & humidity of 65-75 % work great for this. When we are in veg and early flower controlling our temperature between lights on and lights off is very important to have a nice tight stacked plant develop & not get too much stretch. If we expose our plants to temperature swings beyond more than 10 degrees less with lights off, We trigger our plants to stretch a lot. So we want to keep it at 79-84 MAX lights on and no more than 9 degrees less with lights off.
Once our plants enter flower our temperature control will be vital to determine how our buds develop. If we grow out our buds in a room that is too cold, We get very dense caked buds but not very big, If our rooms are too warm we get big airy buds with not very much resin. With lights on in flower, we want 77-80 MAX with lights on & no more than 9 degrees less with lights off. But once our plants have finished their vertical growth by weeks 4-6 of flower, If we now open up those temperature gaps to beyond more than 10 degrees less with lights off it will now send extra energy into the budding process and resin production as the plant's genetic responses to this form of environmental stress has changed now and shifted. I would suggest if you have not done so already look up vapor pressure deficit and how it relates to growing cannabis. All growers should study this and get used to using a VPD chart and logging their rooms numbers. Here is a great chart and article on it. https://cerescann.com/importance-of-measuring-vpd/
It is very important when we do any defoliation to do it on a schedule & complete it all the same day. When we pull any leafs off our plants this goes for all plants not just cannabis, They release somewhat of a scream or a pheromone if you will & this alerts all plants that they are being damaged and to shut down growth for 12-24hrs. We must avoid the temptation to pluck leafs off randomly day by day and stick to a schedule. We do not want to be plucking any more leafs off after day 20 of flower as the plant will not produce any more & needs enough to photosynthesize and do its thing.
Also, look into grabbing yourself a good PAR meter and a thermal laser temp gun to better read your plant's needs and safely dial in your lights to their optimal distance. Keep up the great work and if you have any questions please do not hesitate to follow my profile & ask me through DM. I am currently producing a youtube tutorial series for all levels of growers to utilize, If that interests you hop over to my grow diaries page and it is linked off there. Go ahead and subscribe to get ready for the first release. Happy growing friend!
