Am I right I’m thinking Mag def??

[Kel]

Hiya, out of my crop the majority are going well, this one I picture though is a lighter shade of green and I’ve had my suspicions that it may be a Cal/Mag issue although I’ve been watering with a very diluted amount of Cal/Mag + Nutes. Today I’ve looked more closely and am hoping for some of you more seasoned growers advice on what you think this could be. If it is CM then perhaps shall I water with just the Calmag in after perhaps a flush or go straight in with the CM?

Give me the brand of nutes and there NPK values and dosage you are using for each,plus dosage you give cal/mag.

Hi,
We use BioBizz - on week 7 of the grow. All dosage’s shown below are per Litre
~ Bio Grow (NPK 4-3-6) x 3ml
~ Bio Bloom (NPK 2.0-7-4) x 4ml
~ “” Top Max (No NPK) x 3ml
~ Cal Mag (N 4% / Ca 3.4% / Mg 1%) x 2ml

These have been introduced around 3 weeks ago and slowly increased but did use the CalMag from week 3 when we initially ran into a little problem, it solved after this so we continued to use it. We have flushed with pure water around week 3 for two feeds to clear any possible salt build up. The others look dandy and are doing extremely well, I’m just concerned for this one

Happy to receive pure scrutiny so I can learn quickly from any mistakes. Really enjoying my new hobby and taking it quite seriously so cracking the method is top priority

im crap at the diagnosis part,but looks mag ish.i do know biobizz a bit,biobizz is not very strong so need to flush is unlikely.the bloom of biobizz is the only one to contain any real salts,the only bottle to have a crusty lid.not much mg in the cal/mag if you flushed now theres even less mg available.flushing is rarely the answer.
dont panic,chill and wait for proper advice.
keep er lit n good luck.

That's not cal/mag def but keep on giving it at least one tsp per gal anyway.Seeing your calmag has 4% nit I would stop using bio grow and just stick with bloom and cal/mag and top max what ever that is.If your on week 7 of an auto flower you might see a few leaves turning color and this is natural towards the end of there life cycle.Once the pistols are mostly brown stop feeding and just use ph,d water for the last couple of weeks until you harvest her.

I looked at this last night but the details hadn't been added yet. My first thought was N tox.. Now that you've posted the details, I'm still leaning towards N tox. I agree with Nam.. Perhaps cut out one of the N sources and see how she responds.

Kel-- I need normal light pics, whole plant and afected leaves,.. also please fill out the patient form in the colored "stick note" section above this one,.. copy/paste the blank into here, read the info requested in the form there, and fill in here,...
Biobizz is very mild stuff, diluting that usually isn't necessary,.. are you running full strength?

Thank you, this was my initial thought although I’m not too experienced on it so swayed between the both, I’m pleased I’m not too far off the bullet though
