Big Devil XL Auto

Second week. I watered plant #2 at dawn with 0.5L, ph 5.8 and EC 0.7 and 3.5ml/l of Root-Juice. Rainny days have ended, now extreme hot weather is coming progressively. Everything seems fine for now. Probably in 1 and a half week I will water the plants adding bio-grow as well. Plant 2 still seems bigger t Update week 2: plant 2 didn't survive due to something that seemed Pythium, but the roots were perfectly fine, so I am still not sure about what happend to her. I started to think that an insect could bite her. Nobody was able to answer the question in the forum.
