syde00 Reviewed by syde00 on . NITROGEN DEFICIENCY ?? Would everyone agree that these young plants are showing signs of N deficiency ? They are about a month old from clone, only been in DWC for 4 days under 600w HPS, PH fine (5.8) room temp 27c, nute temp 20c, good air circulation. They only started to yellow last night. Rating: 5
