My plants need help

My plants were growing so nicely and then this happened!! I used neem oil for the bugs but used it late evening as to not burn the leaves. The following day I added nutrients and now this is happening :pleading_face:ph is about 6.5 getting ready to test for NPK :weary:Uploading: 0ABB8BBC-B4EA-4B5F-B26E-F1C03DF2FCB2.jpeg…

pics not up. wait til 100% loaded, then hit reply.

It appears you might have an uptake problem. Your roots might not be doing their job properly. I’m hesitant to give advice on potted plants not in fabric. If it were my plant, I’d flush her well. Then I would immediately feed her again.

We could use more info. I agree with @oldmarine - it looks like you may have a PH problem (the most common reason your plants will stop absorbing nutrients properly) or some other form of lockout that is stopping uptake. That, or your soil is deficient now in maybe one or two different nutes.

I highly recommend filling out one of these:

Following along

  • What strain, Seed bank, or bag seed—tall plant is Black Widow and the others are skywalker OG; seeds came from ILGM
  • Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF—organic soil (coast of Maine Stonington Blend)
  • Vessels: Pots, Grow beds, Buckets, Troths—5 gallon buckets with drain holes on lower sides and bottom
  • PH of Water, Solution, runoff (if Applicable)—not sure; I tested the soil and the ph was 6.5
  • PPM/TDS or EC of nutrient solution if applicable—not sure what this means but I did feed them once with Jack’s 20-20-20 a few days before all this happened
  • Indoor or Outdoor- outdoors
  • Light system- natural sunlight
  • Temps; Day, Night—75-92
  • Humidity; Day, Night—lots of humidity. I can’t control Mother Nature and live in a humid environment
  • Ventilation system; Yes, No, Size—not sure-they are outside
  • AC, Humidifier, De-humidifier,- no
  • Co2; Yes, No- no

The plants we’re doing well and then I used neem oil for bug control. The following day I used jacks 20-20-20 for the first time. I feel like I gave them too much nutrients :sob: however, I fed with half the recommended dose. They were flourishing until this happened. I’m thinking the soil blend was plentiful and I didn’t need anything additional. How do I flush them. I really want to be able to salvage my plants

I filled out the questionnaire also

I’m willing to bet money this is where your problem lies. Find an EC/TDS meter. This device measures the total dissolved solids in your plant’s runoff water and will give you an idea of what the nutrients in the soil look like. For example, if the reading is sub 500 ppm (parts per million), your plant will need more nutrients. If it goes above a certain number of PPMs, you have a serious problem with too many nutrients (hence lockout and/or nutrient burn and uptake issues). The “above” number actually varies quite a bit from plant to plant - I’ve got one plant that likes it in the 2400ppm range and others that don’t want more than 1200-1500ppms. Other people on the forum have had successes over 3k but I get nervous of nutrient lockout in that realm.

A good TDS/EC meter is going to come from Apera, BlueLab, or another reputable company. However, anything will do in a pinch - some folks use the cheap ones off Amazon with some success and frequent calibration - I broke my $6 cheap one from Amazon in about 2 weeks, so it served it’s purpose but I’m much happier with my BlueLab.

Get a bunch of distilled water - water them with 3x the amount you ordinarily feed them and give them a day to recover. It’s a stressful (albeit minorly ) endeavor for your plants and they will probably look sad for a little bit after the flush. They should perk right up afterward though - 24 to 48 hours.
disclaimer there are probably pros who have done this more than I have who may offer different guidance. Follow their advice if it conflicts with mine. I’ve had to emergency flush about 3 times so not a whole lot of experience yet in that realm.

I seriously recommend getting a meter to check your PPMs though - it’s an invaluable tool when you start to feed nutrients (making sure you’re putting in what you think you’re putting in) and check runoff.

Flush is just that, you’re flushing the soil of all nutrients. I would use about 3 gallons of plain neutral water (ph 7ish) per gallon of medium. Once you finish flushing you should refeed the plants immediately. Don’t wait for the plant to “dry out”.

Edit: Take it slow when flushing. You want to saturate the pot before it starts running off. Remember, you’re trying to remove all the nutrients, contaminants or whatever.

I did try flushing yesterday but I don’t think I used enough water. I’ll do it again today. Should I wait until the evening when the sun goes down? Will that make a difference?

At this point you need to weigh the risk. Ultimately it’s your decision what you do. You could do everything I said and still lose her. If you don’t do anything else she could survive.

You’re Johnny on the spot so to speak. Good luck.

I think I’m just going to pray and leave her alone :pleading_face: I’ll let you know in a couple days what it looks like. Thanks for your input :blush:


Just remember to watch the new growth and not the leaves that are already damaged. The spotting very likely won’t go away, but as long as new leaves are growing in happy and healthy, you’re back in safe territory.

So I did a soil test. The ph is perfect. However, the N is really low, P is high, and K is high. Any suggestions??

Or should I just pray for the best?

What do you have on hand in terms of nutrients?
