.5) Do you have an exhaust fan and a circulation fan? Yes
.6) What are the bulb wattages, kelvin ratings, and schedule? 234 total watts, 2700K on the CFLs, 12/12

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) FFoF
.8) Size of container. 2 Gallon

Your nutrients and water:
.9) Source of water. (tap or filtered) What's it's ph? Tap, 7.6
10) Method of checking water ph. (ph pen, test strips, aquarium test kit...) Aquarium test kit (liquid test)
11) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) ph up/down
12) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. -
13) How often are you watering between feedings, and how much per watering? watering roughly .5 quart every two or three days. Its very unspecific, I usually just see how wet the medium is
14) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) nope
15) Are your ph levels stable, or do they fluctuate? mild fluctuation
16) What is your ingoing water's ph? ...your runoff ph? 7.6 in, 6.0 out.
17) Do you foliar feed? If so, with what, how often, and at what time do you spray? no

Your growroom:
18) Indoors or outdoors? Indoor
19) What size of closet, room or hut? Converted dresser, about 4' tall
20) What are the temps and humidity levels while lights are on? ...With lights off? 77-80 on, 70 off
21) Have you seen signs of insects in the growroom? none

Your strain:
22) What strain are you growing? (Indica dominate or Sativa dom?) Shark, or so I'm told. let's assume it's bagseed
23) From seeds or clones? seed
24) Is this an autoflower strain? not that I know of



So basically, I'm a week into flowering and my leaves are all sorts of goofy. I tried using MG orchid food once or twice during veg (rookie move, I know), and then bloom booster a few weeks later when I thought the leaves needed a bit more phosphate (ratios are 30-10-10 and 15-30-15 respectively, used at 1/4 strength). They have been on just water for about 3 weeks now, with the same symptoms.The newer leaves are showing with dark green centers and bright green outer parts, with some yellow/brown spots and a lot of curling. I'm operating under the impression that the ph is the culprit, but I'd like some input if possible.Attachment 279994Attachment 279995Attachment 279996Attachment 279997Attachment 279998

Oh, I've been using lst too. I cut one of the two plants out of it in hopes of relieving some stress.

I'm guessing pH issue related to water pH in and depleted pH buffer in the soil.

Here are a few suggestions.

1. Don't add any nutes if you are using FFOF. Perhaps a little phosphorus boost in flower at week 4, 5, 6 but that's it. 1/8 strength.
2. If they've been in those 2 gallon pots for more than 4 weeks up-pot immediately to 3 - 5 gallons.
3. Get a proper pH pen. The test kits are pretty inaccurate.
4. Get pH going in right - between 6.2 and 6.8.
5. Give a little molasses but not in conjunction with phosphorus.
6. Don't be tempted to through chemicals at the problem. It is likely to make it worse. Start with the transplant, a little molasses and straight water. Give it a week and see where they are. Also note that the damaged leaves will not recover. For signs of recovery monitor new growth.

Nice job filling out the form. Smart. May people skip this step. It helps considerably and motivates others to help you!

I was really hoping to finish out in these pots

Oh well, back to walmart.

update:
Turns out the grow box is too small to house two larger pots. One little lady is looking strong, the other still has dark green centered leaves with bright green outer portions. Some yellow spotting here and there. Anything I can do to resuscitate without re-potting?

[bigsby]

It's hard to say. How much longer do they have? Also, remember that any recovery will take a week to materialize so don't make changes and then more changes without giving the plants a chance to react. Also note that the damaged leaves are what they are. They won't recover, although if you done the right thing, they should stabilize unless they are damaged to the point that the plant has decided to jettison them. You should be looking at new growth to gauge what is happening with the plant, not the older damaged leaves. Pics?

Mine was a splitting image to that and it turned out to be root bound!!

[kingjustin]

Thanks for the input friends. They have about 4 weeks of flower left, so im really not too sure what to do. I suppose this grow box is really only big enough for one plant, just sucks that I have two viable ones now and a severe lack of room.

[kingjustin]

Just ordered some 5 gallon grow bags- hoping the dimensions of these will fit better than rigid pots. Wish me luck!

those pictures are crappy.
