Yellow and growing

[DabbedOutDemon]

They have looked like this for months there coming out of being in rockwool into coco there growing but stressed and look like shit I need them to turn around so I can have a crop what’s going on I ph at 5.8 use Remo mars led

 

[Streetpro09]

How close are the lights and how much nutrients are you feeding?

 

[DabbedOutDemon]

There getting around 4-500 ppms and the lights prolly over a foot away

last 2 days got velokelp and calmag sprayed them with that mix then 3 days ago day of trans plant they got 300 ppm feed 5.7 ph

so today they got cal mag velokelp rapid start microbes
Now they do look better then a few days ago but fuck are they mad what’s your thoughts @Streetpro09

 

[Streetpro09]

I don't grow in coco but from the sounds of it the light is too close for the amount you're feeding. Idk what your root structure looks like. Probably raise the light and feed them more until they start looking better. I would start at about 500 ppm and see what happens. Maybe some others will chime in who grow in coco.

 

[F series]

Are they actually growing or just staying same size?

Most likely a root problem

 

[Old ST1R]

I use Remo Nutrients, but in soil or Promix and I don’t do PPM.

How close are you to the bottle dosing to get to your 500 PPM? They look like they are starving for food to me.

Also could be locked out. Did you use new Coco? Did you buffer it?

 

[Zaphod420]

Totally Looks like they are locked out to me. You say your PH is 5.8, is that a reading from your run off or just a reading from what you are feeding them?

 

[treefarmercharlie]

I agree that they look like they are starving for N. How often are you watering and feeding and are you watering/feeding until you get runoff?

 

[DabbedOutDemon]

before they were transplanted I always fed to run off…I just checked them this morning and there looking kinda better I’ll throw up a pic in a sec

 

[DabbedOutDemon]

This is this morning

 

[Streetpro09]

If you think all is well after what everyone has mentioned, then it's probably a feed issue. Give them more food and they might start looking even better.

300 ppm is low for hydro where the roots have access to the nutrients as they need. In coco the roots will have to search a little to find the nutrients. To compensate for that you have to had more nutrients. At least that was the way it was explained to me when i tried to grow in coco.

 

[DabbedOutDemon]

I don’t think all is well I’m just trying to show and tell everything so I can find the right answer is all I appreciate all the help from everyone!!

If that is pure coco it looks awfully dry. Coco should be watered at minimum of once a day. How often do you water? PH and EC of feedings?

I would collect some runoff and test the EC/ppm. If it's way higher than what you are feeding you probably have nutrient build up that will cause issues with your nutrient ratio balance and pH.

That would be my first step

 

[DabbedOutDemon]

If I water today until run off and there have only been transplanted maybe 5 days ago will I have over watered them to flush that’s my only hang up on flushing because there newly transplanted

 

[DabbedOutDemon]

Yes I use pure coco I had to get a few different brands on a shortage o hear coming for coco so I grabbed what I could I usually ph 5.8 and I don’t check ppms unless there young plants

 

[DabbedOutDemon]

Later tonight I planned on watering everything with calmag and some microbes at 5.8? Should I have a more even spread of water over the pot?

 

[treefarmercharlie]

Growing in coco is a form of hydroponics so you really need to treat it that way. You need to feed and water until runoff pretty much daily when you are running pure coco. It sounds like you aren't doing that so your plants probably aren't getting the nutrients they need.

 

[treefarmercharlie]

Should I have a more even spread of water over the pot?

Coco needs to be watered until it is all fully saturated and you get runoff.

 

[DabbedOutDemon]

Gotta ya so full spread the fed water out tonight thank you!!!

 

[DabbedOutDemon]

Ok folks I fed them at 5 mls a gallon from Remo and a touch of silica everyone had run off let’s see what happens

I felt there could be hungry to that’s why I fed them agood dose of food
