Hello all! I??ve been lurking for some time reading and learning as much as possible, but from the success I??ve had I should??ve come forward earlier. After >1 year of unpalatable and disappointing produce with an old feeding schedule, I??m finally feeling somewhat successful with a new program as the flowers are much fuller, powdery, and aromatic. However, now into my 6th week of flowering, my fan leaves are curling?the sides curling down, but now some are curling up. Leaf color is still good with no indication of over fertilization, other than the curling. I??ve been (finally) feeling like things are going good for me, but now I can??t help but think things are beginning to take a turn for the worse?which is why I??m inquiring. I just need some piece of mind since I don't have anyone to refer to in person. Therefore I filled out as best as I could the Troubleshooting Form - Peat-based mediums Q&A and included it below.

I ??was? using an old HN 10-week Organic feeding schedule that eliminated the base nutrients (essentially Nitrogen) at week 3, but with the most recent effort I??ve been using their new schedule that continues base nutrients up and into to the last week and also includes a Ca/Mg additive. Within the last month I??ve also included flower enhancers in the program. The new feeding schedule has shown to be very promising so far. Below, I??ve included links to both schedules for reference (I hope this is acceptable).

What is your experience level? (first timer, novice, experienced...)
First time grower?25+ year consumer.


Your Equipment:
1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's)
400w HPS - flowering

2) Distance from tops?
~1.5?? for flowering

3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...)
Max Wing horizontal reflector

4) Is there a consistent fresh air supply?
Yes

5) Do you have an exhaust fan and a circulation fan?
Both. Circulating fan runs constantly, and exhaust fan is temperature controlled.

6) What are the bulb wattages, kelvin ratings, and schedule?
Gro Bright 400w HPS, not sure Kelvins, 55,000 lumens, 12hr on/12hr off

Your medium:
7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)
Premier Pro-Mix BX, no additions.

8) Size of container.
2 gallon

9) Did you use peat pucks (or similar) to root clones or germinate seedlings?
Root clones via rooting powder, and planted in small pots with Pro-Mix and light nutrient water.


Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?
Well Water. Our well water is from a shallow sand and gravel aquifer and is potable straight from the ground without treatment (no iron, sulfur, etc.). It is from the same shallow aquifer from which there is a tapped well-known and well-used spring just down the road. EC is ~120-140 ppm, pH is 6.4-6.8. In case it matters for soil growing, the water DO is high at ~ 9.5 mg/L, and ORP is close to 190 mV.

11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)
Hanna pH/EC pen

12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)
I purchased for this adjustment pH Up and pH Down solutions. I mix nutrients in gallon containers, and let sit (shaking a few times during so) for > 24 hrs prior to adjusting pH and feeding. pH typically lowers during this time and I generally have to adjust up.

13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.

Approximately 600 ml nutrient solution per pot per week. I??m currently using Humboldt Nutrients New Organic 10-week program, please refer to the above link (I hope you don??t mind) for quantities as they change weekly.
The only substitutions are?
- Botanical Pro Grow 3-2-4 (in lieu of HN Grow Natural 2-1-6)
- Organicare Humex 4% Humic Acid (in lieu of HN Hum-Bolt 8% Humic Acid)
- AN Tarantula and AN Piranha (in lieu of HN Myco Madness, HN Maximum, and HN White Widow)
The only additions to the HN feeding program are the bloom enhancers.

In summary:
Base Nutrients
Botanical Pro Grow (3-2-4) veg and flowering
HN Bloom Natural (0-10-0) flowering
HN Deuce Deuce (0-0-22) flowering

Additives
HN Equilibrium (Ca/Mg supplement) flowering
Organicare Humex (4% humic acid) veg and flowering
HN Flavorful (8% refined humic acid) veg and flowering

Bio-Innoculants
HN Prozyme (80 enzymes) veg and flowering
AN Tarantula (19 bacteria) veg

Root Stimulants
AN Piranha (26 fungi) veg
HN Humboldt Roots (root stimulant) veg

Carboydrates
HN Honey ES (sugars) flowering

Bloom/Flower Enhancers
AN Big Blood (purchased, never used yet)
AN Big Bud Powder
AN Overdrive (purchased, never used yet)


14) How often are you watering between feedings, and how much per watering?
1 watering in between feeding, ~600ml per event.

15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)
Just started with AN Big Bud powder (1/3 tsp/gal). Also started HN Ca/Mg supplement (1/4 tsp/gal) as per the new schedule, and been using HN Honey ES as sugars.

16) Are your ph levels stable, or do they fluctuate?
Never measured soil pH?yet. I??ve been toying with the idea of purchasing a soil pH pen, but thought since I??ve been introducing adjusted pH nutrients and water that soil pH should be relatively constant and correct.

17) What is your ingoing water's ph? ...your runoff ph?
I try to adjust to 6.3-6.4. Never measured runoff.

18) Do you foliar feed? If so, with what, how often, and at what time do you spray?
Rarely, and only with a light solution of the Botanical Pro Grow. I want to start but feel I need to be successful from the roots up first before foliar additions.

Your growroom:
19) Indoors or outdoors?
Indoors

20) What size of closet, room or hut?
Room, 5??W x 12??L x 3??-5.5??H (sloped ceiling)

21) What are the temps and humidity levels while lights are on? ...With lights off?
Lights on ~80-85F. However, I??ve been venting more recently to keep temps low since this summer it got up to 95F. Off?mmmm?60-75F I??d have to guess. Humidity level is ambient and fluctuates to whatever is outdoors via the venting.

22) Have you seen signs of insects in the growroom?
Few spiders, but none on any plants, that is until a few days ago when I removed one jumping spider that was on a leaf. I eliminate whenever necessary. So far there is no indication of smaller insects around/on the plants or in the room. And the vents are filtered to assist in keeping insects out of the space.


Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?)
Not sure which is dominant. I was told it is a Blueberry/Diesel cross, which was obtained from a reliable source.

24) From seeds or clones?
Clones.

25) Is this an autoflower strain?
Not sure.

26) And last but not least, I can only allow height to get to ~2?? tall due to ceiling constraints, and that is why the 400w bulb. I have plans for an inline air-cooled reflector/fan system to regulate the temperature better, and possibly go to 600w. But first things first, I need to know the produce is good before proceeding any further.

Thanks ahead of time for any and all recommendations to troubleshoot the curling and hopefully get tips to fine-tune my growing techniques from the info provided.
