Anyone know what could my issue be? I have light yellow new growth leaves, slow growth and some leaves on the smaller plant show burnt tips not a lot of leaves only a couple. I been feeding in the 600-650 ppm plus 100-125 ppm of cal mag range and 6.0 ph. Water to runoff. Last run off I checked and it was at like 560 ppm and 6.0 ph. They are in coco. I’m not sure if I have a lockout or what. Any info in the right direction is appreciated!
Any idea what I’m dealing with

Looks like phosphorus deficiency. And cal mag. Assuming you don't have a soil pH meter...What's the medium feel like or smell like. If it's rotten smelling or slimy feeling runoff, or too wet, it's too acidic. Likely no cation exchange site available for nutrients. Humic acid will help with this. As will pH up like, specifically dolomite lime.

pH is fine
What's the temp? Low temps = slow growth
What's the temp? Low temps = slow growth
Temps in room are from 74degrees to 78. 50-55% RH
So the coco feels normal and not slimy or too wet. And I don’t get a rotten smell off it when it’s wet but it does have some kind of smell. I’m not sure if coco has a slight smell when wet. I’m new to the coco. And runoff water is normal. If my runoff ppm is in range and not excessive shouldn’t my medium be fine as far as not being acidic? I been giving it calmag at 380 ppm between feedings. I did that before the last feeding. Would a flush be needed? I’ll get the dolomite and try that or Humic and see if I get any results. But any other recommendations? I appreciate your response!

Temperature as mentioned by another. Cool soil temps affect phosphorus uptake and others. Feed a compost extract at least weekly. Just take compost, like a gallon put it in a pair strainer bag and dunk it in 4 gallons of water till the bag runs clear. Then water the solution in. This is made fresh to use fresh, do not think bubbling it or brewing with this and a dash of that is needed.
Appreciate your response
Got you! Thanks everyone that responded! I’ll raise the temp in the tent also it has been cold when things started to get like this.

I wouldn’t do the Dolomite. You could end up chasing PH if you do that (been there). If your coco was new and buffered with calcium etc then don’t add dolomite lime.
Id say your coco is soaked - at the bottom.
Sit you bags up on bricks.
Because it looks like your runoff sits in two inch trays.
I have them on pot raisers, can’t see it from the angle of the picture. And I do take out the water in the saucers I just to that picture while the water was still in the pan. I am using the Mother Earth Bag Coco pre buffered.

Let them bottoms dry ,then water slowly from bottom never leaving any...watch them suck it up until they cant...prebuffed mix doesnt need more calmag ..thats more for what tomatoes use more of.....You have uncharged coco that you xtra buffed , works best wicking water from the bottom and top dresses 1 time a month from the top .

Thanks I’m going to check how wet the bottoms are. I usually do check the bottom to make sure it’s not wet to the squeeze before I water.

I still think they have wet feet. Otherwise it needs to be warmer.
I don’t use bags I use self watering pots.
They have a suspended tray 1/3 from the bottom and a 3inch reservoir at bottom. This allows the whole bottom section of the medium to drain properly but also wick back up as it needs to. I don’t even have to lift my pots to know if they are hungry. If I stick my finger in the overflow hole at the bottom and it’s dry or low I know how much to wet them with. Either from the top of add to the bottom.
I usually water from the top.
Sounds good. I got the temps at 80 degrees now. I’m gonna let them dry out and make sure the bottoms are dry and go from there!! I appreciate you. Thanks

Well if letting them ‘dry out’ fixes things it will be proof that they don’t drain properly.
Coco doesn’t need to do a wet/dry cycle it is designed to hold ‘field capacity’ (the correct amount of moisture) but it can only do this if if can drain freely.
Copy! I’ll see what happens and let you know. Thanks

Hello Stay,
I was looking for mention of this:
Are the stems and petioles showing red pigmentation ?
zeem
Yes they bounced back. Definitely looking better. The green is back. Thanks for asking
I feel they are stunted though for sure. Or at least stopped growing until I got it back on point.
