Hey there friend, Looking good! If you do not mind I would like to offer some advice and try to help out. So first off cannabis plants love heat and humidity. It is the buds that hate it. So in veg and early flower we can exploit that fact for more vigorous growth. Your temps right now are a little on the cool side & humidity as well. This stage we want a nice warm humid enviroment for our little ladies to grow up healthy in. Humidity in the air will supplement the smaller root structure with foliar intake and speed up growth. In veg we like low 80's with lights on and no more than 9 degrees less with lights off. Humidity of 65% to 70% for the first week or 2 is very helpful as well.
Another thing we want to be aware of, Is cannabis plants will stretch a lot if we expose them to temperature fluctuations beyond 10 degrees between lights on and lights off. Your swing in temps is a little to much right now at 13 degrees. We want no more than 9 degrees less when the lights go off to keep our growth nice and tight.
If you have yet to do so get yourself a thermal laser temp gun and a PAR meter to better read your plants and get the most potential from your lights. I would also recommend researching VPD, Vapor pressure deficit and how it relates to growing cannabis. If you have any questions please feel free to ask. Check out my 200 light 7,000 plant diary & follow my profile and youtube for videos. Keep up the good work!
@Kolibri,bruh you grow 50 gram plants and you say you grow for 12 years,skill builds up slow there ... you soak your seeds in nutrients...why ?!?! just why ?! learn to germinate first then grow
