Nitrogen toxicity

as long as you fix the N tox before flower it will have no effect on final product

Yeah I deffo ain't gonna put these into flower. More likely in the bin lol nah I'm trying to stay positive just ugly to look at. The low feed flush should have dealt with the N toxicity issue, fingers crossed.

Just seems a few different opinions on the other deficiency which leaves me bit clueless lol . Is it P or Cal, the Mg is bit easy to spot so look out for more signs of that. Know just a foliar feed with Epsom salts will deal with the Mg if that is appearing. But yeah what should I look to treat as been told different deficiencies, P or Cal. Both look quite similar.

I wouldn't trash them , they looks way better then most

well the coco releases phosphorous when its cations aren't buffered with calcium , this can cause an issue, so you might have too much N , P causing antagonisms on other elements

excess P from coco is effecting your micros , and your excess N doesn't help either

I deffo have too much N imo. So you think also too much P rather than a deficiency in it?

I was stuck between thinking a Cal deficiency or P deficiency. Can't put my finger on which one to try treat.

Thanks for the words of confidence about not trashing them. I get stressed out with it lol just want my ladies looking healthy again and in flower. Be proper happy when this grow is out the way like.

Did you get calmag?

Yours end up recovering all good and producing decent bud? Go on cheer me up lol

The plants recovered from the nitrogen toxicity.

yea looking at the chart your N is probably the main culprit but excess P from unbuffered coco is also possible , since you use tap there is probably some calmag present but think of it this way. let's say we have 300$ (ppm) to pay bills (coco ) + (plant) you always have to pay the coco bill each feeding let's call it $150ppmfor easy math , now you still owe the plant money so we gotta give up another $150ppm to equal the $300ppm. some coco requires more ppm and some plants require more/less. its possible you've gotten away with paying the coco bill because of heavy calcium in your water but if you stop paying that bill they send the Police(phosphorus) after you to collect. Best analogy i have for Cation exchange capacity lol

keep in mind the more coco surface area you have the more calmag you owe the coco so its ratio goes up

Right I don't want to jinx it just yet but the strain with few waxy leaves but got away with the clawing. They looked okay anyway compared to the clawing fuckers. I still decided everything's getting a 0.8ec flush. Two of the clawing plants needed so water yesterday so they got the low nutes flush. I don't wanna say they look happy but imo they are looking better in regards to the clawing leaves. The new growth looks okay.

If anything the plants now seem like a bit yellow? I doubt that's the nitrogen flushed out already as was only yesterday. Same as I doubt that's them hungry again because only got a low feed. This seems more of a deficiency look than hunger imo.

So order a bottle of cal/mag tonight and use that on them? I will try it on just one plant first to see how that does as a test. If its a Calcium deficiency that should take care of it. If a phosphorus deficiency now the N toxicity is getting sorted and excess gone. The plants should be able to start taking up the correct amount of P.

They arent looking great yet by any means but yeah I do think just from the light dose flush yesterday there is some improvement. New growth doesn't seem to be clawing. I will take a photo when I've jumped out the bath.


Thanks for the replies is appreciated honestly.

Right this ones gonna be pic heavy as want to be sure I know exactly what I'm up against. Don't wanna try treat the wrong thing and cause more problems.

Here is one the ladies



And another one..


The other strain which also had N tox but seemed less effected. Although I will say even this strains branches seem weaker. Not that if you bend them they will snap. More like growing thinner. Maybe that will help diagnose the deficiency.

Then another ..

This thread needs more calmag,LOL and a little more fertigation.Probably a country song in there somewhere.
Your plants look good,just need a little boost.

Sorry to be a pain but thought this photo might be more help. Looks like P deficiency to me more than Cal?



That said I'm gonna order a bottle of cal mag anyway.

Fingers crossed that with the feed being increased slowly back to a decent range since they was flushed. Hopefully will see me able to flower them in a weeks time.

Ordered and will be here before the weekend. Fingers crossed that start to see some healthy new growth. I think the clawing issue is sorted from the flush. The cal/mag taking care of the leaves plus food slowly making its way back to a normal range.

Also really hope with the toxicity and deficiency issues sorted the branches start to feel normal again. It's weird to describe how they've gone. If I say weak you probably think I mean snap easy but I don't. More just growing thinner. Like before you could pinch new growth to train the plant and you'd get the stem to pop and fold. Now that isn't the case.

Youve been growing for awhile yes?I assume your watering to runoff daily if not twice a day?

Watering daily to run off yeah. Why you ask that mate? I ain't got issues with growing a plant. I just ain't used to running into problems like this. Have had problems like everyone but yeah this is probably the worst I've had my plants looking tbh.

Just wanna flip them and get this grow out the way asap lol . Suppose should look at it as the chance to learn.

Is this a new strain for you?Like I said in an earlier post perhaps lower the N part of your nutes or raise the P,K part.Last grow I had 6 different strains in flower.Was a shit show of mixes.Had three pails of different levels.One strain I had would do just fine with a really low mix but had to have the calmag or she yellowed.Others screemed feed me more.lol.Couldnt find a mix that they all liked.

I have run both strains before weirdly. That time was me doing them from seed n all was fine. This time round I got cuts from a mate. Honestly want to be done with it lol . Ready know what I'm running next. Sooner I put these fuckers into flower the better for me.

Sorry to keep spamming the topic. These two wasn't the worse looking. Either way though I think they are looking better. The cal/mag arrives tomorrow so will start giving it that then.
