So I found out that indeed my ph levels were way too low, around a 5.0. Spent all weekend flushing and bringing the ph up to around 6.3. So far so good because none of the plants are dead and looking perky. Now, i have AN taruntula, grow big, and superthrive on the way to help out the recover but i believe the plants look like there 2 weeks old rather than a month since they've been growing since aug 19. Any help tips please let me know. 400 watt hps bubblicious grow.
