    Exclamation 3rd organic grow with big problems!! Help please

    Hi guys,

    This is the 3rd run for me with new seeds. The plants started off fine but have all developed a lime green appearance with some leaves whithering and browning. I use RO water and grow organically so only use molasses, and liquid seaweed currently. My pH when watered is around 6.5 and the run off is closer to 7 but nothing crazy high.

    Ive been trying to solve this problem but I am really stuck and i don't want to leave it too late since the seeds were expensive!

    Any and all help is appreciated and I can provide any more information is necessary.
    I have attached a few pictures below to show you what i mean.

    Thanks

    Hey Purple, not sure if this will help im very new to this. I had a similar problem with my first grow, thought it was a cal, mag, iron problem but it turned out to be a PH problem. If you are in soil I would try get your PH down to 6. My problem was I was not checking my nute tank ph daily left it a couple of days and PH would sky rocket up I noticed when I checked my run off which was coming out at a PH of 7.8. Oh is everything I have learned the hard way. I used what was called Dr Repair by CYGNO and water.

    Just wondering if seaweed and molasses contain all nutrients and minerals required for growing? RO water has no minerals or trace elements.

    Yes and no . If the soil is well built it will . Adding seaweed and letting it compost in the soil a good while will release the nutrients .1-2tblsp per gal will do well of high quality Atlantic Kelp .

    As a last minute thing it wont help much . Best get some worm shit and make a tea with it .

    1 cup of worm castings per 1 L of water
    1oz blackstrap molassez

    Let a rolling brew with air pump for 24 hrs .
    Strain ....
    For large plants dilute in with 2 L of water with 1 L brew .
    . Small plants 1 L to 4 or more if you feel lezs feed is needed .

    Use the the leftover worm shit and top dress top of plants with it.

    Thanks for the recipe. I will use it this weekend for my organics. Any real point to the filtering? Any reason to not just top water and let the solids pour out with the tea? Cheers!

    Not really . It just clogs my damn watering can lol .

    You can toss in some seeweed alsoin the brew . Grind it in a fine dust as much as possible . Toss in a same amount as worm shit . Dilute a bit more just in case .

    Would it be okay to toss some oyster shell flower in there for calcium or should that be dressed into soil? My city water is toxic and kills plants. After I filter it there are no minerals left in it. I constantly struggle with calcium and magnesium deficiency.

    Hello purple

    Stumbled across your grow when looking for organic grows, thought id chip in it could be just something as simple as over watering, how often are you watering them, what size are the pots and what are the normal grow temps and humidity? oh and what soil?

    Default acidic soil

    Hey , that is lock out due to ph. Acidic organic mixes driving it down....its a ph fluctuation... Add lime to soil runs in future , i add a few table spoons of lime per 11L it just keeps the soil in a good range no matter what. Garden lime is fine but there's better stuff dolomite lime I believe. Sorry you had this issue I had it before....sad face. Best flush a lot. Did you perlite the soil? Get lime and add a tablespoon to ten litres and stir and water them a bit each and wait. Don't go too hard to fast. Then spread a half handful on the top soil of each plant. Good luck.

    Interesting this yellowing with plant magic soil. I have had it on both my plants and they never recovered, no matter what I did. Its still growing well and nearly finished. I will not be using plant magic again as I've read too many of this same story now.

    Closer to Michigan than Chernobyl. I am told that it is the ancient pipes that provide the water that is the issue. Comes out of the reservoir filtered and balanced and then goes into pipes so old that the rusting metal mixes with the water. Comes out of the faucet brown.

    I wouldn’t advise putting lime anywhere near my soil especially if you plan to do a no till or a raised bed because the magnesium to calcium ratio isn’t right and eventually it calcifies the soil.

    What’s your original soil mix? Most liquid/extracted seaweeds have shit missing your much better off getting a bag of kelp and doing s tea. Or there’s numerous things you can do depending on your original soil mix
