First RDWC - West Coast OG/Super Lemon

•End of week 1 after transplanting to RDWC and start of week 2. •The roots finally have showed themselves and are snow stark white, thick overall healthy looking, but the plants do not look happy compared to my soil grow. •They’re dropping, stunted, light green to yellowish. •They’re about half the size of my soil grow and I cannot figure out what is wrong with them. -If anyone reads this and has any suggestions, please help! •After increasing PPM to ~430 the next day both look much better, but still look a week behind my soil grow. •Both are growing roots pretty good now, but the Super Lemon isn’t catching up like the WC OG. •Light proofed buckets with Reflectix R21 insulation. •Res change/clean after 8 days and plants are looking better. •Couple days after res change and both are looking much happier and showing signs of new growth on top and below u. The root zone. •Finally was able to start lst on the WC OG, but will have to wait on the Super Lemon-if it even grows big enough to lst. •Have to add an ice pack once in awhile to keep temps under 70F-res hovers around 68F majority of the time. •Topped off res with 1/2 gal mixed with 2ml A/B + 2ml calimagic + 0.3ml S. AG and PH down to lower PH down to 5.8 from 6.0
