Rollitup Community:
I am in my darkest hour here, very frustrated and discouraged. I worked so hard on my room and invested a solid amount of capital in order to make my dream a reality. I have been a grower for years, but this is my first 4k setup. I will let the pictures speak for themselves as far as the problem is concerned but a quick backround as to what is happening. The plants veg fine (Under T5) and start growing fine under the HIDs during week 1 of flowering. At the middle of week 2 the plants start to develop the symptoms in the pictures and they continually get worse. This is my third cycle in a row where this has happened! I have torn the room apart, bleached everything multiple times. I have switched strains, clones and have had this problem consistently. I have used soil, coco, and now rockwoll with the same problem persisting. PLEASE HELP!
Strain: GDP
Medium: 6 Grodan Rockwoll with coco mat underneath
Lighting:
(4) Lumatek Digital 1000watt HPS w/ Hortilux bulbs
Nutrients: (Flower)
GH 3 Part + Liquid Koolbloom
Purple Maxx (Have NOT used)
Gravity (Have NOT used)
GH ratio is as followed on the label, one tray is at 2-2-2. The other tray is 1-2-3. PPMs are HIGH at 1300 1500 on average, I am constantly battling PPM and PH.
Nutreints: (Veg)
Great White (rooting hormone)
GH 3 Part
Water:
PPMs are 60, I run my water through a Hydro Logic Tall Boy (R/O Pre Filter).
Feeding Schedule:
Lights come on at 7:00 PM
Flood at 7:00 PM (5 mins to flood the table, 15 mins to drain)
Flood at 1:00 AM
Environment:
80 degrees F (finishing construction, needing to run another 120 to get my AC going)
50% relative humidity
CO2 300PPM (not using my burner until I get this sorted out)
10 vortex ducting the lights
10 vortex cold air intake
12 vortex on a Can 150 for exaust
Reservoir:
55 gallon drum like used in the CAP ebb and grow system. I have 2 airstones in each reservoir agitating the solution 24hrs per day.
Nutreint Storage:
I store my nutes in the dark in a Rubbermaid shed outdoors where temperatures reach 40 low to potential 75 high.
Nutrient Mixing Technique:
I have a bypass on my 1000gph pump and run it until my water looks like a bubbling cauldron. I mix GH Brown first at full strength to 30 gallons, I let that mix then mix in the Green diluted in a 5 gallon bucket and pour it in, followed by the same procedure for the Pink. PH usually settles at 5.8 6.2
I cant get the pictures to upload so I put them on Photo Bucket here is the link
