Coco Coir yellow leaves

Mother Earth coco
5 ml of GH Micro
10ml of Gh Bloom
Tap water with 5ml Cal mag at ph 6.0 or 5.8
Also used Gh Rapid Growth at 1/4 tsp on clones pretty much every watering

Clones looked really good in the beginning and growing fastest ever and all of sudden leaves started turning yellow and stunted growth. I did a flush and now 6 weeks in and see little new growth but not much.

I seen to always have slow growth on myclones and added the rapid growth and they took off and huge roots right away this time
Even my mother plant is acting up too and I did water her s few times with rapid growth in the water. Picture 4 is the mother plant with twisted leaves

Any suggestions flush again

How often are you feeding and at what EC, PPM?

Are you feeding to run off?
Why do you think you need calmag?
Try using the Lucas formula for coco..........6ml Micro/9ml Bloom.

Yes feeding to run off My first few runs I had what looked like mag def so I started using cal mag and plants looked better. I had 2 okay runs with some decent smoke and now issue after issues with the same strain Super lemon haze.

Ditch the root stuff,doesn't do well mixed with the veg nutes.
edit doesn't

Might be a long shot here but I have this 1 strain that likes high 20's (celcius) and decent humidity.
It exhibited almost the same symtoms as yours in cold weather with bright LED's until i put a heater in the room.

I will ditch the root stuff. Just crazy in the beginning I had big white roots stinking out the pots and now no roots mass and super slow growth.

My clones also grow roots quickly once transplanted and i dont use root stuff.Theres been a few posts around here with people having trouble with it.By itself its ok but mixing with veg nutes doesnt seem to click.

Thank you. I see some new growth but not much. I think I will flush tonight and start off with a fresh batch of water and nutes with no root enhancer

Interesting. I did Super Lemon Haze last grow and came out okay, but I do get slow growth in the beginning. I was thinking maybe my shop lights need new bulbs in veg room before they go into the flower room

If you're using tap water you probably don't need the calmag regardless of growing in coco. The GH Micro is 5% calcium and the Bloom is 1.5% magnesium. Then there is some in your tap water as well.

Calcium induced deficiencies do happen and with the way everyone seems to be dumping calmag on their plants from day 1 it's likely causing some of the issues people have. Too much calcium can lock out potassium, magnesium, and other elements.

Minus any tap water Ca...
This is how 5/10 with calimagic breaks down at ppm level. Approximate not exact.

Kinda high on Ca, low on P and Mg, but that's just a wag.
Keep feed ph and EC fairly consistent. PH around 6.2 often helps with Mg uptake.

Adjusted. Just tossing out for comparison.

Rookie here lol

My water is super hard like 400 PPM plus when I start so I'm already starting off on the wrong foot. I apologize I might have a few questions. I appreciate the chart and helps a rookie break a few things down. I will do my best not to confuse anyone. One question I do have is how do I know how much CA NPK and MG I need of each at certain times in my grow? On the first chart you have 35MG to low but second chart has 66MG and that seems to be good ratio. How do I know that 66mg is a good ration then. Then first chart has P at 10 and low and second chart P at 29 and okay. Do you have a link to a chart I can plug numbers into? I couldn't copy my water report but here is a link if anyone wants to take a look. Are those valid questions or I'm a completely lost?

From Chart i can tell 1ml of nitrogen is 16PPM. Also on first chart you used micro and grow and I was actually using Micro at 5ml and Bloom at 10ml
I appreciate the help and probably throw the plants away and use R/O and start over

Same strain... same nutes..... the issue is that it ISNT THE SAME....

I bet you $100 your ph meter has drifted.... you need to calibrate your shit every fortnight bro!
