I've read a lot about the yellowing and browning of leaves and what it could be. But am still not sure with my situation. They started just at the bottom and a couple of small leaves have died. But on a couple of plants the yellowing has seemed to spread and brown spots have developed. I'm almost 4 weeks in veg. I'm leaning towards too high ph, but I'm also worried about nutrient levels. I've been going a little above 7.0, at most 7.5. I thought it was good to have right on 7, but now I'm reading a lot of people are going lower for soil growth.
I have copied and pasted this trouble shooting page I found:
What is your experience level? (first timer, novice, experienced...) first timer
Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's) 2 MH 400 watts
.2) Distance from tops? 1 ft, maybe 1 ½ ft.
.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...)enclosed reflector
.4) Is there a consistent fresh air supply?yes
.5) Do you have an exhaust fan and a circulation fan? yes
.6) What are the bulb wattages, kelvin ratings, and schedule?
Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) Pro mix, watered with Great White when first transplanted to 3 gallon bucket
.8) Size of container.3 gallon
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?germinate seedlings
Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?tap, 7.2-7.5
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...) ph pen
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) PH up, down
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. Flora Micro, Gro and Bloom / one tsp each in 5 gallon bucket of water. Watered 15 plants in 3 gallon buckets
14) How often are you watering between feedings, and how much per watering? Watering every third day with 5 gallon bucket of water, only gave nutrients once about two weeks after transplanted.
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) just great white
16) Are your ph levels stable, or do they fluctuate? fluctuate
17) What is your ingoing water's ph? ...your runoff ph? 7.2-7.5, haven't really done much ph adjusting, haven't checked runoff
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? No, just mist with regluar water
Your growroom:
19) Indoors or outdoors? Indoors
20) What size of closet, room or hut? 4x4x7
21) What are the temps and humidity levels while lights are on? ...With lights off? On 24 hour light schedule. Temps have been 75-78 and humidity has been 38-45 mainly.
22) Have you seen signs of insects in the growroom? One tiny bug once
Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) peanut butter?
24) From seeds or clones? seeds
25) Is this an autoflower strain? ???
