I have recently jumped into the world of growing and I have started coming into some issues. (I do have pictures I will post links to down toward the bottom in an edit) I have poured through pictures, descriptions, forums, manuals, etc. I have been able to piece some general information together and come to a general idea of what the plants are doing, but it would be great to get a second opinion.
18 plants. 1 Plant has ALWAYS been curling, slow, stunted, dark, but still growing so I figured I would let her grow instead of having an empty bucket.
Only 3 of the other plants are showing any signs (within the last 3 days) of the same type of leaf deforming, color change, etc. The others appear to be doing great, but some are pale green, others are nice healthy green.
I came to the conclusion that I have have been creating a pH lockout of nutrients in the system because I was running around the 6.0 mark instead of keeping it right between 5.8 - 5.9. It also appears that I may have a deficiency of certain nutrients, so I jumped to a different ratio of nutes as well.
Info for the questions is below:
1. How tall are your plants now?
- The tallest are approximately 42 inches, the shortest are around 30 inches.
2. How far from the lights are the tops of your plants? Is this a constant distance or have you changed it recently?
- Outdoor greenhouse
3. How old are they?
- 12 are 8 weeks old and 6 are 5.5 weeks old
4. What strain are they?
- Purple Power Feminized Outdoor
5. Did you start them from seed or clone?
- Seed in rockwool cubes
6. What type of containers are you using and what size are they in gallons?
- 5 Gallon black food grade plastic buckets.
WHAT TYPE OF GROW DO YOU HAVE?
11. Hydroponic?
- Dutch Bucket system. 18 buckets. 32 gallon reservoir. Perlite size 4 coarse.
WHAT TYPE OF HYDROPONIC SYSTEM DO YOU USE?
13. NFT
WHAT TYPE OF LIGHTS DO YOU USE?
- Outdoor clear roof greenhouse
24. What nutrients are you feeding your plants?
GH Flora 3 part series
HYDROPONIC FERTS?
25. What brand? What mix? What strength?
Last week (7 days) Based off of GH Simple recirculating feeding chart I Was running Week 2 Nutrients, 10, 7.5, 2.5 Grow, Micro, Bloom (per gallon) This is the ratio that I was using and I brought the EC up to approx 2.0 + or - 0.2
After reviewing the symptoms of the plants and making my best guess I decided to jump to week 4 Nutes.
Based off of GH Simple recirculating feeding chart Week 4 Transition Nutrients 7.5ml, 7.5ml, 7.5ml Grow, Micro, Bloom (per gallon) This is the ratio that I am using (as of today) and I bring the EC up to approx 2.0
26. How often, and when was the last time?
- I dump and replace solution with fresh every 7 days (Wednesdays)
ENVIRONMENTAL CONDITIONS OF THE GROW AREA
29. Do you use ventilation for your indoor grow?
- 1600 CFM Exhaust Fan at apex of greenhouse roof and 500 CFM intake blower fan at bottom bringing in cool outside air.
31. Do you use a fan?
- Two oscillating 14 or 16 inch(can't remember) cheapo fans.
33. Temperature of the grow area?
Low temps at night around 60 degrees F, and high temps during the day around average 85 - 90 F, but at times the greenhouse will breech the 100 F for no more than a couple of hours.
34. Humidity of the grow area?
- Outdoor Oregon Coast Humidity depending on temperature between 60 - 70% when it's coolest to 30% when it's hottest.
35. Is CO2 being introduced? What method?
- No additional CO2 is being introduced into the grow tent.
36. Do you use Odor Control, (carbon, ionizer, ozone gen)?
- No
37. Do you use LST? HST?
- I do not know what this is, so I am going to assume not.
HYDROPONICS/Aero Ponics/Coco/Soiless/
How long has this problem been going on?
- I noticed the issues starting to get worse about 3 days ago, however I have noticed some leaf curl for about a week.
Are you growing in a PVC grow tent? (example: Hydrohut or any other non brand tents)
- The tent is a UV treated tarp setup typically used for carports, etc. I replaced the top with a King Canopy Clear top 10 x 20.
What PHASE are the plants in? (seedling, vegetative or flower) are the plants in?
- Veg as best I can guess based on the sunlight
What substrate/medium are you using?(Hydroton, RockWool etc.)
- Size 4 Coarse Perlite
What is the Water temperature?
- 71 - 78 Deg F
What color are your roots? White? Brown? Are your roots slimy?
- Unknown what color they are or if they are slimy
How often are you feeding? (If using soiless)
- I have been topping off with Fresh water each day and then adding proper ratio of nutes to bring EC up to the 2.0 mark, then pH down to 6.0 ish (Between 5.5 - 6.5).
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
- Micro, Grow, Bloom
What is the TDS/EC/PPM you are using?
- 2.0 + or - 0.2
What is the pH of the "Tank"?
- WAS 6.0 + or - 0.5, NOW 5.8 to 5.9
Are you sure your calibration is correct on your equipment?
- Yes I am positive the calibration is correct, I have verified with different base calibration solutions and I also have more than one pice of test equipment I can use to cross reference.
When was your last watering?
- 4 times a day. 6am, 10am, 2pm, 6pm. WAS 15 min watering cycle NOW 30 min watering cycle
What is your water temps?
- 71 - 78 Deg F
When was your last feeding change? (ie. grow-bloom-micro-additional)
- 6am this morning was first feeding with new nutrient mix (as stated above)
Tell us about your ventilation, intake exhaust and when its running and not running ?
- Oscillating fans run from 8:30 am - 7:30 pm. Exhaust is on Temperature control 85 degrees, intake blower is also on temperature control 75 degrees.
Is the fan blowing directly at plants?
- No oscillating fans are blowing over the top of the plants.
Is your water HARD or SOFT?
- Soft
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water?
- Reservoir tank water system. (42 ppm) Zero Chlorine. We are on a city water system, but the water sits in a giant tank reservoir long enough to evaporate all of the chlorine before it gets to my house.
Are you using water from a water softener?
- No
Has plant been recently pruned, cloned off of or pinched
- I recently topped the tallest plants, and pruned some of the large shade leaves, but not excessively to my knowledge.
Have any pest chemicals been used? If so, What and When?
- I treated the inside of the greenhouse before any plants were inside with some turbo bug killer Raid barrier stuff, but gave it plenty of time to dry and air out before moving the plants into the tent.
Are plant's infected with pest's
- No, not at all.
I will edit the post and add some pictures below after they are posted shortly.
