Too much nitrogen? clawing plant

[Stunted]

20ml of Nutrifield A+B in 8 ltrs of PH 7.0 water will drop the PH of said water down to 5.7-5.8, then you add some more additives and that will drop the PH even further.
And starting with a PPM of 0 that 20ml of A+B will get it to around 1000ppm......

The nutrifield coco a and b are pretty much cal and mag with a couple extras

UMMM NO! just NO....No NO NO
You would do well to obtain some Cal/Mag for future use, especially if you are running LED lights.

SO my 10cents says you are torturing your plants with some seriously low PH!
As you are using Coco I would suggest you mix a light mix (10ml A+B in 8ltrs water) and flood that plant on a biblical scale, keep flooding even after it is flowing out the bottom. If it was me I would be putting at least 3x the pot size of liquid through it. You need to get all the stuff out and start fresh.

Flood it every day until liquid runs freely out the bottom, leave to drain well and prop it up so it is not sitting in any water.
Do that for a few days then post some new pics.

Best of luck with your grow,

Hi - Just stumbled into this thread. I'm pretty sure - like 99.5% - that it's not the Mosaic Virus (that's from lab growing capsicums and potatoes - both of which are susceptible to Mosaic Virus). Cant explain the brown spots tho.

However I grew Northern Lights Auto this year, can't remember the supplier. 2- out of 3 popped and they were very different plants indeed. Similar height but one had a really compact leafset with dense bud sites clustered around a main cola. The other looked a bit like yours. A loose bud formation on quite elongated flower stems. Lots of large sugar leaves which curled and twisted like yours - this started more or less as soon as flowering started. Could be just a genetic hicup - the NL strain showing a different phenotype.

Will be interesting to see how yours turns out or whether the feeding tips work out.
