New Growers I wasn't meant to grow in coco

Good evening.

It's just as well I've made an appearance on this forum again because I'm encountering my first problem with my first grow in coco while trying to follow the percy coco grow guides.

I feel awkward posting on here after being absent for so long. But I don't want to post on any other forum and go through introducing myself again. Some of you will know me. I have to do a little shout out to Macky. Twisted. Monkey. Colacody. Hart. Fish.. Somebody won some pipes and donated them to me. I'll never forget that. Thank you. 

Anyway 

I hope some of you can help. Maybe I've got this under control but I'm a little unsure. 

A few notes to acknowledge.

These plants that I just not long started off were meant to go down the same route as my other 4 which are in hempy buckets. But I didn't have enough perlite to share out between them. So I just thought I'd run them in coco instead. I wish I hadn't and I wish I just went out and bought some perlite because for me hempy buckets is a game changer. Low maintenance and so far so good. 

OK here goes. 

The lower first set of leaves are starting to yellow on one plant They've only been in their final pots for 1 day.

What I've done is I've started my seedlings off in a soil/coco/perlite core. Which is what I did with my hempy bucket plants.. And I've just not long transferred them into their final 7 litre pots. In future I'm definitely going bigger. I just went for the 7 litre pots so I could fit more plants into my space. 

The coco came in brick form. To prepare it I soaked the bricks in lukewarm tap water then afterwards I used my hands to squeeze out most of the water..

I then went and got some vitalink calmag and dropped 5ml in a 5 litre drum of dechlorinated tap water. I let the coco sit in this for 6 hour's... I then repeated the process of squeezing out the water. but not all of it.

I mixed in a little perlite and gave it all a good mix up

When I transferred the 2.5 week old seedlings into the pots filled with the coco. I watered them using formulex @ 5ml per litre. I didn't water for run off.

I figured I'd do this when I feed them next.

This morning after realising that my hempy plants were slightly underwatered I noticed the yellowing on my plants growing in coco. Just one plant or maybe 2.

I'm aware that the coir needs to be moist all the time and it can't be allowed to dry out. I need to water to flush out the build up of salts... And I must not allow the coco to sit in its run off

I quickly rattled up 5ml per litre of formulex followed by 1ml per litre of cal mag in a 5 litre container. I phd to 5.8 and feed each pot until I saw a good amount of run off. 

Is there any thing else I need to do other than change to a stronger nutrient feed. I know that formulex is weak. But it's all I have atm. I do have hydroponic nutrients that I'm using with my hempy plants. Which is vitalink hydro bloom sw A&B 

I'm sure I did read that it's not recommended to use hydro nutes in a coco grow even though growing in coco is classed as hydroponics.

I know some of you are going to ask what the ec is of my nutrient feed. And I can't answer that as I don't have an ec pen.

Again these were never meant to be grown in coco because I'm aware that ec tests are required in coco. Maybe they're required in hempy grows but the guide I'm following suggests that you don't need to bother with PH or EC. Although I'm always measuring the pH of what goes into my hempy buckets and what comes out.

It's the plant in the middle that concerns me

Any suggestions please and thanks.

Hey Stars, good to see you again. First of all I know you’re nervous about your plants but they aren’t looking that bad yet so you should be able to save these. It looks like some nutrient burn starting on that center plant, that browning along the leaf edges. Generally I like to flush out the excess cal/mag out of the coco before planting into it. The cal/mag that the coco uses to buffer itself won’t be lost but the flush removes the extra unneeded material from the root zone. The nutrient level might be a bit high as well but we don’t have Formulex in the US and I’m not familiar with it. The instructions say to use 5ml per liter but I start my nutrients at 1/4 rate. If you’re putting in 5ml in 5 liters that shouldn’t be a problem.

Being as you are in coco, the best/easiest thing to do when you have a problem is to flush and reset the media then refeed the container. Ph water to 5.8, use 3 times the volume of your pot and flush out the pots. Then refeed each flushed pot with fresh feed once the flush is done. This will give the plant a nice balanced zone for recovery. I’d mix cal/mag at 0.5ml/liter and 1/4 of the recommended strength of the formulex for the initial feed levels. Eventually, it would be handy to have an EC meter available to help diagnose problem but I understand the situation right now. We will do the best we can with what you have. The burning on the leaves won’t go away but should stop getting worse.

Check the hempy plant @ the back right. Never seen a plant like that before.

@thestars yer man, that plant in back is really showing her wide leaf indica traits. It’s a beautiful thing. If those plants keep on this trend you should be looking at a very good harvest.

@thestars glad your in a better state of mind bro, always good to see people on the upside. Life can be a motherfucker to say the least but a place like Percy's can really be a safe haven and a grounding place for people to just get out of the hectic bullshit for a little while and reset. And nothing makes your heart warm like raising little green ones into buds! Glad @monkeydo got ya sorted, I knew he's the right guy for the job! 😃

Do better, feel better.
