I have 3 clones in 3 gallon fabric pots. In coco coir. I was feeding every day while in 1gal plastic pots and was giving them about 200 ppm cal mag, and about 500-550 of A&B nutrients. (Humboldt secret nutrient) total 7-750ppm at 6.0 Ph. I water until runoff. More than 15 percent runoff. The highest my runoff ppm was about 1100 at one point and I was bringing that back down to the 7-800 range. They was doing fine at first. So I made up a lighter mix around 500ppm between callas and A&B combined. And got the runoff down to that 500 range incase I have any lockout. Been running 5-550 for the past 3-4 days and the new growth kinda looks like it’s is coming in good. Just wanted to see if anyone had anything else to input. New to coco and trying to figure it out. Not sure what I am doing wrong. Tent temps is 78-80 degrees Fahrenheit humidity is 55-60. Any advice is appreciated in advance. If you need more info let me know. This is my second try at coco and I get to a few weeks then boom. Growth stops or slows and leaves start to lighten up. Clones are on beginning of week 3 for veg. Two weeks they wad about 3.5 inches tall so they was growing good. Help lol
Any have an idea what my issue is?

I forgot to mention in the first post. I’m still watering once a day with runoff. And the runoff was at or around 1100 for a few days that’s when I made the lighter strength mix to bring it way down. And that’s where I’m still at. 550ppm 6.0 going in. And that’s still 170-200 ppm of cal mag. How much cal mag should I be adding on the regular when things are going good? Oh I’m using RO water. Sorry! Everyone and everything I read that you have to add the extra cal mag with coco and RO water but nothing says an amount or ball park range.
The picture down on this message is the same clone i put in a grow happy bucket with their soil mix in it. And the clone looks way better than the other 3 in my opinion. It’s more perky and greener and the growth is still noticeable by the day.

Have you considered using tap water and eliminating the calmag?
It crossed my mind but at the same time my tap is coming out around 360-400 ppm. That’s high

Do you drink your tap water?

They look pretty healthy to me, what's your question, exactly?
Just seeing if anyone might see something wrong with them. I may be over thinking it all. Just wanted to make sure. I just put them in the 3 gallon pots on Friday. So I’m gonna watch them over the next few days I don’t think they have any shock from the transplant. But I was just curious if someone other than me might see anything before it would get worse. I appreciate your response and Mickfoster. So you think they are in good shape?
