Sulfur toxicity and low P issues

My soil test results show me having well over 200ppm more S than suggested for hemp .(I'm guessing I went to hard on gypsum and maybe langbeinite)

Somehow I didn't charge enough P into last recycle either.

Looking for solutions as the clones I got basically aren't growing at all and I've had them for like 2mo now. Kind of crazy as I was expecting to be flipping 3 to 4 by now. One has branches that are brittle. I took 2 of them for cloning as I don't see this plant surviving. Never ran into an issue like this before where everyone just stopped growing.

I flushed the plants some last night and will too dress bird guano for P with some ewc and buus compost.

Also planning to make a tea with the guano as well.

Your soil's nutrient sequence is out of range. You need to change soils friend because the amendments you want to add will take too long to work. Those additives you are adding will be very slow to break down.

A faster fix is changing soils by transplanting the root ball with the old soil, and put it in new fully amended fresh organic soil. Maybe even store-bought FOX Farms for a fix.

Gently dig up the clones and take the root ball and a little soil and put them in new soil. Maybe a little larger container for flowering and wait for them to start growing again. Either way, keep us posted friend.

I know I could replant. I have 2 other bins of cycled soil, bit I'm waiting on test results before I dive into it after the current issue popped up. 3 of the plants are already in 7s (1 I may just kill since I took cuts). The others are in 4" still and can easily be moved

I jist tried to add photos of my analysis and the plants but keep getting server error uploading each.

I did give all pots a small flush last night too

1- don't trust anyone who diagnoses your soil condition without reviewing an analysis.
2- 200 ppm S over recommendation is nothing. Folks who follow Slow nickel gypsum ministry get S ppms @2-5k and grow healthy plants.

Try taking a phone pic of your analysis and attaching .

Thanks ahead for any help. I've been super stumped which is why I got a test ran. Been growing some real nice shit since I switched to making my own mix during covid

That's nothing for sulfur, lol. Look at this 😂🤣😂 I am in the ground not in pots.

Damn. I don't get what's going on at all in my grow aside from the lack of P then .

These ladies should all be way bigger and ready for 7s. The ones in 7s should be almost ready to flip but obviously not 😆

To me it looks like your lacking on roots and IMO your soil looks heavy but I grow in coco indoors in pots so I am not the one who can help you. Creeperpark should be through soon to give you good advise. Good luck

What did you say you were growing, to be getting a range from they. They seem to be talking field numbers.

I can clearly see the details you tried to cross out with the blue pen.


I'm seeing carrots and enough damp in the saucers to concern me.

That isn't my analysis. That's the other guy showing me his outside plot has way more sulphur than my homemade mix. Mine is a few responses before that one (he probably crossed out his home address.

I flushed some last night that's why you see damp saucers. My carrots are almost always turned back 2 full notches vs 1.5

I wonder if you have root aphids or something that is messing your roots up?
I have discovered potworms recently. But I only spot them in too damp soil. When it's drier I don't see em as much. No fliers .. I haven't had gnat issues in ages. When I transplanted to 7s I didn't notice anything on the roots not even the pot worms. I've put plenty of BTi and nematode down on the last month too. I still have a nematode in fridge I have to use in next cpl weeks

Yep my 1st true failure since I went water only org
And the micronutrient lack of was the first thing one of the farmers I work with job wise who runs a giant organic tomato and mango farm. Unfortunately his two initial suggestions I believe are commercial purchase only lol

LOL, glad I crossed my name and address out. Being color blind sucks. Oh well. If anyone wants to visit me I am a cool cat 😁. As for the recommended numbers, they are for a basic vegetable garden.
