Brown spots on leaves and tips of seedling 9 days old.
What is your experience level? first timer
Your Equipment:
.1) Type and wattage of lights. LEDs
.2) Distance from tops? was 6in now moved up to 12in
.3) Reflector type? none
.4) Is there a consistent fresh air supply? Yes
.5) Do you have an exhaust fan and a circulation fan? Circulation fan only
.6) What are the bulb wattages, kelvin ratings, and schedule? 90w 24/0, no sure about Kelvin rating.

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) (soil will be MG seedling starter. soil less hydroponic with hydroton and white foam.
.8) Size of container. red cup not sure..... hydro not sure either.
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? NO

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting? Tap,left out for 2days ppm 100 or less. ph 7.4 adjusted to 6.3
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...) Ph meter pen i guess?
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) ph down/up
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. FF grow big 600-700. nothing on the soil on yet.
14) How often are you watering between feedings, and how much per watering? soil uhm 2 time each time let water run off.
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) None
16) Are your ph levels stable, or do they fluctuate? Stable move up/down by 1/2 points
17) What is your ingoing water's ph? ...your runoff ph? did not test run off water.
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? No

Your growroom:
19) Indoors or outdoors? Indoor
20) What size of closet, room or hut? 1.5x5
21) What are the temps and humidity levels while lights are on? ...With lights off? hum 39-45,temp about 70-77
22) Have you seen signs of insects in the growroom? No

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) WhiteBerry
24) From seeds or clones? Seeds
25) Is this an autoflower strain? No

ph is too high for hyrdo and a little low for soil. grow big might be too strong at that stage also, try just foliar feeding until it really starts to move. use ph adjusted water only for a while to keep roots wet.

dont try, do. seedlngs dont require much nutes and ph needs to be close as you can get to the target range. 5.5-5.8 for hydro and 6.5-6.8 for soil.

the soil is mg should i flush it to try and get all the nutes out? i just replaced my hydro with 5.8ph and 100ppm ff. :thumbsup:

just spray them and keep the root zone nute free. when you get some more nodes transplant and/or start feeding nutes. soak the soil with the sprayer or gently pour it in, just relax and let it set in.
