@ Keylime. Thanks for stopping by!! Water comes from tap, thru 1/4" drip line, thru the described filter(not problem IMO), no metal lines near nutrient fluid and lastly I calibrate meter once a month 7.0 and 4.01. Meter is a Hanna pH/EC/ppm meter.


What is your experience level? Experienced novice

What type of hydro set-up are you running? Recirculating drip system

B) Distance from tops? 6?-12?
C) Reflector type? Enclosed reflector/ vented
D) What are the bulb wattages, kelvin ratings, and schedule?
Veg.- 400w MH 19on/5off
Bloom- 600w HPS 12on/off (also have a 400w HPS that??s not on yet, both are on a mover)
E) Is there a consistent fresh air supply? Yes
F) Do you have an exhaust fan and a circulation fan? Yes
G) Size of reservoir? 18 gal total, 8-10 gal used
H) What medium if applicable. Hydroton w/rockwool

Your nutrients and water:
I) If using rockwool for clones or seedlings, did you rinse the cubes well, with properly ph'd water? Yes
J) Source of water. Tap What's it's ph? 8.0-8.4
K) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
GH FloraNova system
Veg.-GH/FN Grow(1tsp per Gal) and Flouralicious Grow(1/2 tsp per Gal) 1000-1200ppm
Feeding- DWC/constant aerated
Bloom- GH/FN Bloom(1tsp per Gal), Flouralicious Bloom(1/2tsp per Gal), Liquid Kool bloom(1/4tsp per Gal) and Dry Kool bloom(Not used yet) 1100-1350ppm
Feeding- 15 min. intervals every hour starting 1 hour before lights on and con??t thru lights on, once during lights out
L) What is the ec/ppm of your unadjusted tap (or filtered) water? 70-170ppm
M) What is the ec/ppm of your nutrient solution? 1000-1350ppm
N) What is the temperature of your nutrient solution? (reservoir high and low temps) 72-76 F
O) Does your ec/ppm show a rise or fall when you do your daily PPM check? Slightly raises
P) Does the ph fluctuate? Yes, from 5.6 to 7.0 in 24hours
Q) Do you foliar feed? If so, with what, how often, and at what time do you
spray? (Just after lights come on, just before they go out...) No
R) How often do you replace reservoir water/nutes? What does it look like before changes? (clear, foamy, green, brown...) Every 5-7 days, tan tinted clear with some sediment

Your growroom:
S) What size of closet, room or hut? 10??x2??x8?? bloom area 10'x2'x8' veg area
T) What are the temps and humidity levels while lights are on? ...With lights off? 85/60% on, 75/65% off
U) Have you seen signs of insects in the growroom? Yes, fungus gnats
V) Are the roots long and white, or brown and slimy? Long and white healthy looking

Your strain:
W) What strain are you growing? Nirvana AK-48 and NL#5xHaze
X) From seeds or clones? AK-48??s are clones from seed, NL#5xHaze clones from dispensary?.reason for the F??ng GNATS!!!
Y) Is this an autoflower strain? No, photo-period

In bloom, I??m having problems with yellowing lower leaves and reddening stems. I also think the buds should be a bit further along/filling out better. I??m thinking Nitrogen deficiency, probably from pH fluctuations or maybe nutrient lock-up!? All leaves close to buds are nice and green but the fan leaves at the major intersections are the ones affected. I??m not ruling out the F??n GNATS but my roots look healthy/white/searching? HELP the first 4 plants in flower have been there almost a full month. These are the plants showing the worst problems.

Please, any help/advice is greatly apperciated!! :jointsmile::hippy:
bleupitbudz Reviewed by bleupitbudz on . Need help with rising Ph....! I've got a bit of a dilemma...! I now have 12 plants in bloom, 3 sets of 4, spaced out by 1 week. My problem is rising Ph. My water that comes into the grow area goes thru a cylindrical water filter, one you use for water going to a refrigerator. From there it goes to a 50 gallon reservior that is aerated and constantly moving. The water comes in at 7.8-8.0 Ph and 80-180ppm. I'm using GH FloraNova products that after mixing brings that water to 5.8-6.0 Ph and 1200-1400ppm. I run the pump for 15 Rating: 5
