First Run In New Growbox F1 Hybrid Automatic

Here we go! Today week 2 started. We encounter our first problems, but don't worry, we'll figure it out! The 2 big leafs of each plant are drooping a bit, also hints of yellowing. After analyzing everything it is very certain who the culprit is - simply too much heat. We had crazy hot summer days for 4 days straight, temperature inside the box was 30-35°C every day, peaking at over 37°. Didn't do damage at first, but now it's visible. The two plants at the back are also CONSIDERABLY smaller, I guess because they got even less airflow (even when I open the box from time to time the air doesn't change up so much in the back) and thus more heat. My ventilation system still isn't installed, had a lot of stuff happening these days but I'll do it this week for sure, I swear mom! After it'll be installed there should be a good airflow even at the very back of the box, removing excess hot, stagnant air. For now I moved the lamp one level up, risking slowing down the grow a little bit but removing a lot of heat. If you're wondering they can't have light stress, I measured it and we are completely in the norm there. Back to topic, I'm not gonna water the guys for 2-3 days, it's a form of LST, don't spoil your kids too much :p it'll force the roots to search for water and reinforce them (I hope). Also if the issues occur from over watering (which I don't assume but you never know 100%) it'll counter that. After those 2-3 days I'll continue with normal fertilizing scheme from terra aquatica which is 1ml/l for early veg. I'll reduce water TDS from 1.2 to 1 since the substrate should be saturated by now. Day 13 Update: yesterday I bend over two of my girls (lol) and today another one, the last one is the smallest and she will be 3-5 days I think until she's ready. Before bending them down I removed the biggest leafs located at they bottom of the plant, but only the one which would be tucked under the plant after bending and thus getting very low amount of light. On the next day they were looking up again so ne Problems here.
