I have two plants in DWC that are about 3 weeks from seed. The lower growth keeps yellowing/dying while the newer growth looks much better.
I'm using Advanced Nutrients PH perfect 3 part w/ RO water. PPM was about 5-10 before adding the nutrients, now its around 400. (2ml per gallon of each of the 3 parts) PH stays around 6.2. I haven't added anything else per recommendations from AN. I have a 400 watt led grow light about 30" above them.
Each plant is in it's own bucket with w/ its own airstone. There is also a reservoir with a circulating pump that runs 15 minutes of every 60. The system has about 10 gallons of nutrient solution total between the 3 x 5 gallon buckets. Humidity is pretty low in the room, around 34% even with a humidifier running. Temperature is around 75, water temperature is 69-71. I recently switched to 12x12 even though the plants are small, i was doing 18x6 before
This is my first attempt with PH perfect, i have several grows under my belt
I thought it would be simpler to use PH perfect w/ RO water and not have to worry with adjusting PH, adding cal/mag etc... the water looks perfectly clean, roots are nice and white, everything is perfect except the plants lower growth looks terrible! Almost wonder if it could be a pest problem.
I'm not sure what strain these seeds are, I had a plant hermie several grows ago and kept the seeds, this grow is from them. Is it possible the genetics are just bad? Seems unlikely. Thanks again in advance!
