One quick before it's hot

Day 36 ( 24/052021): 3rd week of 12/12 starting. Watered all plants , 1,8 L/plant, pH 6,2/6,3, with Elycitor (0,45 mg/l) and Roots + 0,3 ml/L. They don't seem to want more grow stuff and that's fine for me. For sure the DNA with cork is rich enough for 4/5 weeks and All mix for at least 3. I thought of adding some Orga grow during the third 12/12 week to make sure they don't miss N but...they say " no ! Thank you that's fine !": The tips of some leaves are slightly clearer ( not burnt at all, just clearer), I read somewhere that's its the sign that they have all what they need => More would be too much. It's not very visible on the pictures but yes, it started to flower everywhere. The Quick kush are now the tallest and the latest (less pistils for now than all other strains). Talking about size... The strech is not over: 7 cm today... 51 cm, they're not that tall but I'm still surprised: it's already a X 3,4 stretch and I don't plan to defoliate.. Ha ! and the smell got stronger and I had to re install the air carbon filter and also to use some ONA in the room while watering (several hours ..): Tent opened it smells too strong to be quiet. Day 37: + 4 cm today. I moved a Critical 2,0 and placed an empty pot under its plate so that it's +/- at the same height than the other plants. I finally also cut the 3 first nodes 's leaves on most plants but a quick kush. Day 38: I visited a friend today and came back home when the light was off => no pictures today. I saw the plants this morning before living: They took 6 cm during the night; nothing else to report. Day 39: Not much to say. They're growing fine and the stretch isn't over. The smell is getting stronger. Day 40: +3 cm again today. Quick kush are late compared to the other plants and they're also the tallest. 1 sprayed some neem oil before the light is off ( 1 L water pH 6,8 + 1 ml of neem oil). Day 41: +5 cm today and I raised the lamp again. It's the 2nd run using the SF 4000. I don't regret one second the purchase and after a few months, I can tell plants love its light with not a single doubt. I'll wait until monday to feed them again so that we are in 4th 12/12 week: stop the roots +, start the Orga bloom and boost +. Finally, they had some grow stuff only once when repoted from light mix in to dna mills / all mix and with 65% of the recommended dosage. Sure nutrients are a factor as well as genetics, environmental conditions and growing techniques. No sure that it's the most important. Day 42: Tallest plant is 80cm tall. Quick kush 's buds are now visible. T° rose ( 28°C outside) and I removed the humidifier from the tent => pic at 27° in the tent. I'd like to stay under 26°C but I don't think it will be the case. Tomorrow... watering, Yesss !😱
