Auto Test German outdoor Summer #2

Welcome to veg week 4. We start with a height of 15 cm and a very hungry plant, that's why I did flush her with 10 l of fresh fertilizer solution today. 28.06. We are having lazor sun and thunderstorm tag teaming all day long, will need to fertilize a second time this week, just to counter the rain flushing all the good stuff away. 30.06. something is fckn up my grow condition, 64 °C at night wtf, growdiaries is a bit buggy day is 31 °C night 17 °C pH 5.5 EC ~1.7 mS/cm daylight is 17:45 anyways, something is definitely wrong. did add 5 l of fresh fertilizer solution 01.07. Ok, here's the deal, we are having rain every day, I'd be happy if this was an open ground soil grow, and my garden is happy as can be, but with coco it's a different story. All the precious nutrients are getting washed away, so I could either hand fertilize at least twice a day, but I am afraid this will lead to a lot of human errors. I think I will try some leaf spray, let's see what I can come up with. 01.07. evening I made a spray with 1 ml/l Plagroon Calmag Pro and 10 ml/l Primastar Universal fertilizer. I know I should be using a surfactant, but my polysorbate 80 is somewhere in a buried move box and something is better, than nothing. I did order some yucca root powder, but for now it's a no wetting agent spray. I already had the Primastar fertilizer and they advertised their product containing "precious humic acid and growth and vital substances", so I'd decided to give it a try. So I gave my baby a throughout spray down and I intend to repeat the treatment after every heavy rainfall. 02.07. the spray did not kill her, will continue 03.07. It seems the spray did vitalize her a lot
