Possible calcium or magnesium issue

[GMO]

looks like over watering combined with too much light for the growth stage

900 ppm is roughly 1.8 EC which i think most here would agree is fairly high for the growth stage

Id say reduce everything except temps and get some airflow over the pots to help em dry out

Thank you bro really appreciated, what would recommend in terms of calmag? 0.5ml/L or drop it completely?

Yeah same as Marcus said mate. the nutrient companies put alot of time and work into having a complete balanced nutrient. the only time (alot of people) use calmag is front loading it at flip, usually a foliar at flip and one 2 weeks after to make sure they glide through flower with no issues

Id prolly look at letting the pots really dry out and start feeding back A&B at 2ml a litre which isn't a high dose for those size plants now. Possible cause of this is your roots are or were too wet, cold and soggy. Fix is let the pots really dry out to kick roots back to life and start back feeding 2ml per litre of A&B every 2 to 3 days. 2ml per litre of those ferts i doubt is 1.8ec and more like 1.2ec. But im not totally sure and i cant be arsed to check myself but yes either way 2ml a litre of A&B on its own of those ferts for that size plant isn`t over the top.

Odd leaf in your picture does like a wee bit like calcium def but if it was you would have it all over plant on older leaves and on newer stuff up top of plant more so.

Have a look at the back of your A+B bottles for the ingredients... It's full of calcium and magnesium already.

There is no need to add any more.

Thank you sir!!!

My brother! Appreciate the help, I’ll hold off calmag now then and back off the a&b

So I’ve fed today as pots were really light and I was seeing the slightest droop starting
I’ve dropped the calmag entirely and fed at 1.1ec which was about 1.75ml/L my theory here is less is more lol…

Fingers crossed

Less is always more brother. This way we learn more. Working with loads of different nutrients and factors just makes it difficult to identify what the issues are. Goodluck with the rest of your grow.

They seem to be coming around!!! One of the plants has been swapped out for another pheno of the same strain

Nice and greeeeen

@2-Scoops @Marcus @wutang
Any suggestions on how long I should wait before I flower the bitches?
I’m currently fertigating daily with 2ml/l (700ppm), enough until run off, should I increase this once I flip or leave as is?

Up it just before flip (I go to 3ml/L normally) and then keep it there for about 2 weeks after flip (could be 3) all depending on when it stops stretching (sort of), then I drop it back to 2ml/L (ish).

You can just bollock them with grub now they're big enough though and keep it on through flower, just keep an eye on them to check they are happy.

There's no rules, you'll soon find your groove.

I;m a cautious scaredy cat though and prefer the lighter side of feeds.
