Ph might be out then mate
I see your in coco I'm a soil man
I'm sure coco grower can give better advice if its nutrient lockout maybe a ph flush get rid of salt build up

Yeah could be dude...ph has been bang on going in,haven’t really started to water to waste yet,so it could be a salt build up,I’ll chuck some phed water through her,see if that helps any.
Cheers man.

Thanks for looking in man,not been giving calmag to the girls in hps tent,I was starting to worry that I might have spider mites! I’ll start adding calmag at 1ml per litre,that sound good?

I haven’t been using calmag on these girls,these are fine temp wise,25-27 degrees,it’s the cob tent that was cold,so these are fine with temps.

Coco tends to need added calmag, cob leds further compound the need for extra calmag. I'd probably go 1.5 ml/L to give an extra boost. I've heard many times that plain water in coco fucks things up, except when flushing and it doesn't matter anymore. Always feed at 1/4 strength nutes minimum throughout until flush. Adding calmag should straighten them out, doubt you need a flush at this point. Hope that helps.

I get what ya saying man...but these are under hps,not cobs.i think they’re not getting enough cal/mag,I haven’t really started feeding these girls to run off yet,only been small amounts of feed...but I’ll add some cal/mag to the feed,and see how they get on.
Thanks for replying dude

If your in coco, calmag from start to flush, no matter the lighting. Cobs mean you'll need even more.

2 to 3 per liter isn't out of the question. Really the most important thing is to start with calmag first watering to avoid deficiency. Cal is immobile, so the plant needs it constantly.

Does that include seedlings? Surely the feed would be far too strong for them?

what kind of cal mag do you use roasty and when your feeding at 2 or 3ml per liter do you back off the base nutes or keep them at the same levels without cal mag

Must be feeding his plants strong solution,he said he uses calmag every feed.ive just added some to mix feed mix,and with what I added in base nutes,came out far too strong.

Seedlings only need 3/4 to 1 ml/L. From the get go.
