I'm a beginner in grow, and need your help with my plant

[wowwow5605]

Hey everyone I'm trying to grow Fast Buds auto in coco coir (Plagron cocos perlite 70/30). I use canna coco start, cannca coco A + B, calmag
In my grow tent tempechure: 25 - 28 degree, humidity ~50 - 60%
I grow in small cup
I use filtered water ppm around 30

Feedeng schedule for my plant:
Day 1: 150ml (calmag 0.5ml/l) ppm ~100, ph 5.9 - 6.0
Day 4: 150ml (canna coco start 2ml/l ppm ~ 170, ph 5.9 - 6.0
Day 8: 150ml (canna coco start 2ml/l ppm ~ 170, ph 5.9 - 6.0
Day 12: 200ml (calmag 0.5ml/l + canna coco A 2ml/l + canna coco B 2ml/l) ppm ~550, ph 6.0

Now day 15 and my plant are small and looks like she has nutrient burn

Images for day 12, she was pretty small and i think that she has nutriend deficient so i decided to switch to canna coco A + B from canna coco start




Images for day 15:



Please help me, what I did wrong and how i can help to my plant?

Transplant it first, roots don't like light, how far away is the light and what type of light are you using

[DabberDog]

Howdy! You've given your plant nutrient burn. The good news is she's growing out of it. Seeds need nothing but clean water for the first 7-10 days above soil.
Your plant is old enough now for a couple doses of half strength nutrients, then full strength.
Cover your clear plastic up or repot it into something solid. You can see mold/moss/green stuff growing at the bottom of the cup in the fourth picture. Roots growing in soil are not fans of light.

I use Secret Jardin Led Cosmorrow 100w, I place it around 30 centimeters at top of my plant as manufacturer recommended

They need bigger pots. Yes nute burn, cut back for a while. Roots don't like light.

[wowwow5605]

Ok, i will transplant it to 18L pot.

Do i need make flash? Or reduce nutrients amount for future?

[DabberDog]

Growing in coco, you do not need to flush if you are using hydroponic or soilless nutrients.
How did it go with your other plant?

[wowwow5605]

This is my first plant

Congrats on your first grow, wowwow!

I agree with the other forum members.

- Nute burn from feeding too soon after sprouting.
- Clear plastic letting light on roots.
- Small pot.

Take some time and read through some of the many excellent grow articles here on the GWE site. A healthy, growing plant is only the first of many steps to a fine harvest. Fast buds has good auto genetics. Coco/perlite a superior choice for grow medium.
Now your next challenges begin.
Are you going to train your plant? How? Got the details on when to harvest? How about drying, curing and storing? All the answers are on the GWE site.

Ah, this one grows very small (


So i decide to try grow in coco, it is my first plant in coco

[wowwow5605]

DabberDog As i now you also grow in coco, I follow this guide - https://www.growweedeasy.com/coco-coir

And in this guid I found image with nutrient schedule for canna coco A + B - https://www.growweedeasy.com/wp-cont...t-schedule.jpg

In this image i see that for first week days (3 - 5) ppm could be more that 600, but how i possible if my plant was burned with ppm 550 at day 12?

Maybe you can give me advices for first 1 - 2 weeks about how to use nutrients, which ppm i should follow if my clear water have around 30ppm?

My experience is with a different brand of nutrients and I don't do PPM or EC. Once you get out of the seedling stage, life is easier. You cannot give a plant in coco too much water, but you can overdose it with nutrients. Start with a half dose. If they can handle it, go full strength. Your plant will tell you what it wants.
Ignore the Solo cup reference, and some folks do not do runoff in coco. Nothing wrong with it, it just isn't necessary. Make sure the water gets to the bottom of the cup.
From the webpage you posted, here's what I'm talking about.

4.) Start Seedling-Strength Nutrients
After seedling grows first set of “real” (serrated) leaves, water with nutrients at normal seedling strength, and add a regular dose of Cal-Mag (Calimagic). Keep giving water until you get about 20% runoff ut the bottom of the solo cup. The first set of leaves are round, but the second set are serrated and pointy. Once you see those leaves, it’s time to water your seedling with nutrients.

got it, thank you for advice

[DabberDog]

Buuuuuttt... what about the other plant? Are you not going to post about it anymore?
