Hello. Ok i have 3 amnesia haze autos going and 1 deisel auto. The lights are 600watt HPS on for 18 hours off for 6. The plants popped the soil on January 23rd. The soil is Terra Pro, theres a pic of it below. I have a 6 inch fan exhausting the hot air and the temps when the light is on is about 80F and 62F when the lights are off. I dont know what my problem is but this grow and last the smae problems appear and my plants start dying, At around week 6 this happens in the pics below, I have not yet added nutes as the bag said 6 weeks of added nutes, im thinking the problem is nute burn but im not sure. Please help me correct the situation.
Feed the things man, you are starving them, the canna will feed for about 3 weeks but when the plants are big ya have to feed em Sent from my SM-G920F using Grasscity Forum mobile app
Give them more light. Put them outside. Get a soil meter like $5 bucks. Feed water every now and then once they flower they drink often. Sent from my iPhone using Grasscity Forum
