Hello
Well here is my situation I have a 4x8 gorilla grow tent I have a 1000 watt HPS running coco nuts canna A and B everything has been fine now all the sudden I have plants 1 by 1 turning lime green and I was just getting ready to start to flower :( I have tried to lower ph tji king this maybe the problem, I had them in soil and switched over to coco but didn't know I was supposed to rinse the coco first but I was having the lime green issues before the switch ...
Here are some pictures of my issues and input would be great

I doubt it is a rinsing issue. Was this the only plant that did this?

Top pic needs nitrogen or you are locked up with salts, I personally don't use coco so can't say exactly what you did wrong.

Second pic looks fine seems like your plant is growing fast and is just a little lighter in the new growth happens all the time.

But the drooping so tells me there may be some ph, or ppm issues.

thank you for looking into this, I never had trouble with locked out nutes (god giving I don't in the future), I've never seen it until this.

Nutrients lock each other out all the time. Look at the Mulder chart to see how an increases of one available nutrient effects the other nutrients availability to the plant.

My guess he is correct what Homesteader said ^^^. If it was just one plant it would be a different story. With locked nutes it can take time for your other plants to 'hit'.

I am guessing that it is a sulfur or mag issue and it is locking out your N which is why it is turning yellow.
