Good day!
this is my first time growing and I’ve searched to exhaustion why my leaves keep drying up. So I’m hoping for experienced growers to take a look if share your thoughts and suggestions.
im growing from seeds, super lemon haze. Sprouted in root riot in 3 days and moved to a DWC system. I’ve got a carbon filtered outlet exhaust, carbon filtered fresh air inlet blower, A cheap humidifier and heater. All devices are running in auto on an ac infinity wifi controller. Temp is 75°f-78°f, humidity is 50% and 65%.Heater turns on at night usually at 70°f. Lights Are horticulture lighting group, rspec350. I have them 24”-30” from the canopy. Umol is from 300-550, DLI 25-35. Im running 18 hours on 6 off. Ph is 5.8-6.2 typically and ppm is 800-1100. Using sensi ph perfect nutrients. Changed water 3 times now, first was 1/3 strength and gradually worked up to the veg suggestion dose, 170ml for 15 gallons water. Filtering water using ro system. Not adding co2 yet. Air bubbler in each tank, recirculating water between two tanks and reservoir. today I added a chiller to get the water temp down to 65°f and raise the tent temp to 80°f.
So far every set of leaves have slowly gotten spotty and dried up and have no idea what could be doing it. I’ve had 1 bout of spider mites, I used lost coast And it appears to have got rid of them. Someone who has more experience looked at them with a black light and said they don’t think it could be fungus or mold. The root riots may have been a little moldy, would this cause it? I’ve followed almost every suggestion with temps, humidities, light intensity, airflow, new nutrients, now chilling water and it’s till happening. Today is day 32 since sprouting. I’ve cut off the first 4 sets of leaves.
Ill post pictures at various stages. I cut off the largest leaves today and are on yellow paper.
thank you
