4th grow, [Dead] Leaf Septoria

Disclaimer: I fill my diaries on the go and update them during the week. So if you like to get all the information and pics of innocent plants getting the herbie101 treatment, always check back on the last week to get the FULL picture (of a grower trying hard not to kill his plants). Thank you, have a wonderful week and happy growing! Day 15: Entering the third week of this run, i made new beds for the little ladies and repottet them to their final 12l/3gal pots. The soil is 80% BioBizz Allmix and 20% Worm Humus. The lower third of the soil got some additional perlite for better drainage. For this week, i aim to let them settle in and feel at home. So we don't change settings and will be still aiming for that 65 to 75% RH, temps around 25° and some airflow. I'll up the light intensity to 40% in a few days, when they had some time to adjust. I don't plan to feed them additional nitrogen for the next two weeks minimum. The Allmix with the worm humus should have more than enough nutrients to get them by for quite a while and their baby leaves are still lish and green. So they should have plenty of storage. But i'll still add Root Juice and bacteria to their water to promote them some juicy root development. I'm gonna switch from misting to regular waterings this week, but we start with little doses to avoid overwatering. Plant training is not going to happen until their topping which may happen in the next week. Instead we practice grower training and try to keep our hands of the little ladies as much as possible. They are currently working on their third set of leaves, we'll wait until their sixth set is up to top them down to the third node again. So far so good. The little rippers are a bit behind their sweet seeds sisters, but only a tad. We'll see how it goes. Day 17: The girls are doing fine and are progressing well. I upped the light to 40% and sometimes the temps get a bit high (28-29°), but i hope i could fix that with increasing the ventilation. And as soon as they drink more and more water will be present, temps should go down a little. At the moment its quite stable at 25-26° again, which is almost perfect. They got 0.1l of water today yesterday. Started to introduce them to regular sips of water instead of spraying. Day 19: My humidifier did not run yesterday, so it was a bit hot and dry what lead to some heat stress. But i guess they'll be fine again soon. A totally unnecessary mistake, but what happened has happened. Besides that they are doing fine and show some decent growth. They got another 0.1l of water.
