Coco grow issues

[Jas4458]

Problem: yellowing stunted and clawing

Medium/grow method: coco coir with orchid chips at the bottom for drainage

Feed: and supplements used: humboldt natural liquid nutes

water source: dechlorinated tap

PH in the root zone: 6.2

Strain/age: Pineapple Express auto (Barney’s farms)

light used: Mars hydro 600w LED

Climate: 76f 60% RH

Additional info: Feels like it has been nute locked the entire grow, extremely stunted and generally just an unhappy plant

Never tried coco, and I think I shall stick to soil! Wish I could be of more help!

@Jas4458 Welcome to AFN.

Did you wash and precharge the Coco?

Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)

-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics! Turn off the grow lights.

This is my second grow, my first time was in soil I amended and mixed up myself and it went well, that said im doing this one in coco coir and it’s been a roller coaster, I’m using the humboldt liquid nutes and following the guide to the T this one is 6 weeks old, any advice would be appreciated. I’m just about ready to yank it up and try again!

Hello growbro. I am in coco, not an expert. Do what I can to help.

What is your PH of your feed. Are the nutes coco specific. Do you water to a good run off each time?

EP3

I ph around 6.4-6.6 I have been watering to run off but I cut back on that and she was showing signs of over watering at first

 

[EP3]

I am lower in PH terms. I aim for 6.0. The best range is 5.8-6.2. It is important to water to run off every time. I was experiencing a build up because of this and my run off ppm was way over what was going in, had run off, but not enough.

Are your nutrients for coco?

BTW, Man o green is somewhat of an expert on these things. Ignore my questions and fill in the form you will get a better result.
I actually deleted the first comment, Mrs wanted me and I hit post before checking again
Cheers,

Very Very Important - did you wash and pre-charge the coco coir? If you did not this grow is over!

I am going to need more precise information about your nutrients.

Humboldt has many nutrients which one and how much did you use and how often?

 

[Jas4458]

I did wash but wasn’t aware of pre charging it

Attached are the nutes and quantities I am using all mixed per gallon of water, and at first I was feeding with nutes and water as the pot felt light but I’ve switched to every other day with plain water at the recommendation of someone who also grows

Update: I decided to pull her up and dry out what little bit of growth she had on her, gonna start from scratch with happy frog since my last soil grow went great
