My plant's currently in week 4 of flowering, but it's been having strange curling on some of its fans. In addition to the curling, the fans also have dark spots on them. I'm thinking it's a potassium deficiency (maybe?), but I'm not sure. I'm on an organic, water-only system, so I wouldn't think it would be nute burn or a ph problem. Sorry for the potato quality photo, and thanks in advance to anyone who can help
Bumping w/ an update: I've tried treating it for a magnesium and a potassium deficiency, neither of them working. I'm all out of ideas on what it could be, temps are fine, water is fine.
Pic' of the whole plant, please... You sure you're not overwatering? In a properly built soil, you should not be experiencing "nutrient deficiencies". If you're growing in organic soil and having issues, you'd be better off posting in the organics section. Tell me about your soil.
Unable to take a picture at the moment, but I'm positive it's not overwatering. I've tried posting in the organics section, but I get an error telling me I'm not allowed to post there, not sure what that's about. Only other thing I can think of is that the pot that it's in doesn't have good enough drainage, I'll have to try drilling a couple more holes in the bottom. Soil's pretty basic, 1/3 peat, 1/3 perlite, 1/3 castings, has kelp, alfalfa, rock dust, and lime added in, can't remember the exact amounts. Basically the mix described here http://forum.grasscity.com/organic-growing/1116550-easy-organic-soil-mix-beginners.html.
Improper drainage, lack of sufficient aeration, and compacted soil will all result in the same effects that are experienced by overwatering. Tell me about your soil. Also, contact a forum administrator to see why you're unable to post in the organics forum.
Edited my last post with details about the soil, forgot to mention that the worm castings were bought from Amazon, probably not great quality, but the best I could do at the time.
That could be your problem. That stuff is not what I would consider to be a "quality" humic source. The first soils that I built contained WW as the humic component of the soil mix. I was very disappointed with the results... You're in CA, right? Did you try Craig's list in your area for sourcing EWC's?
Yeah, I've mixed a new soil batch with better EWC since planting this guy, it's currently cycling, should be ready in about 2 weeks. Definitely a problem, but do you think it's the source of my plant's sickness, based on what I've told you so far?
It's really hard to say for sure without a picture of the whole plant... In organic living soils, the humic component of the soil mix is the MOST important part. Without quality humus, no amount of amending will result in a functionally viable soil. Do you have any more of your "better" (what brand?) EWC left? Any more amendments other than kelp and alfalfa?
The EWC was "made" by me, in my worm bin. I have some left, some of which I used as a topdressing yesterday. I do have some tomato tone, Jamaican bat guano, and Mexican bat guano as well, as far as amendments go.
It's a 3 gallon pot. This plant wasn't meant to be anything serious, more of an experiment of sorts, so it's pretty dinky haha
So you don't think that you're plant might be root bound? How long did you veg' for? One of the reasons why I've asked for full plant pic's... How thick a layer of EWC did you top dress with?
I guess root bind is a possibility. I don't remember how long it vegged for, but right now, it's only about 12 inches tall total, with no side branches or anything. Literally just a vertical stick haha. Applied about 1 inch of EWC
If your plant is root bound, top dressing with anything is not going to help. Roots and microbes need sufficient levels of oxygen in the soil in order to properly cycle and absorb nutrients. All sorts of "nutrient deficiencies" will exhibit themselves when there are insufficient levels of oxygen present in the root zone. The examples given in post #5 all exemplify this condition... You may want to try "aerating" your soil by sticking something (like a bamboo stake) into the soil in several spots and wiggling it around a bit. This will allow more for more air to enter the root zone when you water.
Hehe are there ever, I just transplanted a regular f1 blueberry, ended up the bottom half of her roots ripped off in transplant, so many freaking roots she didn't even wince. No droop, perked right up to the light and happy as a pig in poop! Lol thank goodness for an extremely healthy root system!
