Indoor 4x auto ultimates defeciency

[imka07]

Hi im growing 4 auto ultimates,
2 of my plants have a defiecency, please help me figure out what it is, thanks

It could be a cal mag defiecency bro or maybe nute burn, i would say cal mag

 

[PabloDutchflowers]

@Bailey any idea bro

Looks like a potassium and mag to deficiency to me, I would do a search on google with it and see if the symptoms tie up, what are you feeding her at the mo? magnesium and potassium deficiency usually appear in older leaves first.

You may have copper def. what is your pH?

 

[nudger361976]

Copper is a very uncommon deficiency in general, not saying it doesnt happen but the leaves do tend to curl, wilt then die, plus the new growth struggles to open up.

The biggest problem is there aren't many strict cannibas nutrients available. I'm sure tomatoes and my dinafem seeds require different things. Or even having a autoflower feeding schedule. That's the biggest deficiency. Recently I learned that organics while being great take much more time to work. Chasing deficiencys can be a problem with them.

Theres loads of cannabis specific nutrients available @BigSm0 - Canna, Green Planet, Advanced Nutrients, Plagron, Humbolt Nutrients, Growers Ark, Plant Magic, thats just a small few as an example. Theres many companies that make canna specific soil, nutrients, everything tailored for cannabis. Best thing I ever learnt was to read the plant, never PH'd anything in my life, ill prob have lock out or something now ive said that

Brou what temps are you running and how far are the lights, also wich type of light is important. There's definitely some curling upwards and it looks like light burn or high temp problems...

I honestly dont think thats light burn at all, some of the leaves at the bottom are affected and the new growth looks ok.
