Hey guys, I am a first time grower and have been making plenty of mistakes. Any advice is appreciated I don't know whats going on with these girls but its been rough apart from the first few days of sprouting.

Seeds planted jan. 17th 600W hlg, Holland basics coco coir, pro mix perlite (70/30 respectively), Dutch nutrients in a 3x3x7 tent.

I started by soaking the coco in cal mag and seed & root nutrients, then rinsed it out and planted my seeds in solo cups. The seeds are feminized from royal queen seeds (gorilla glue and bruce banner)

They sprouted looking great and I was giving them ro water with no nutrients for about few days. I started giving them veg nutes before the second set of leaves were even visible and I think this was my first disaster.

Since then they have been struggling and I have tried just about everything to keep them alive since I want to try to get as many mistakes out in this first run before diving in again. I have also struggled with keeping the runoff pH down. Everytime I water to runoff with 5.8 pHd water it is coming out above 7.3!!??

I've attached some pictures, please be kind I realize this is a pretty horrific sight for anyone who loves these plants as it is for me

Did you pH the water you soaked the coco in??

What strength nutes did you use on the first watering?

How close is your light and do you have it cranked or have a PoT to dial it down??

 

[Camden]

All water that I add to it is ph'd to 5.8-6.1
My tap water is about 350ppm so I only added a little nutes to a total of 550ppm
The light is approximately 45 inches from the tops of the plants at approximately half strength using pot.

82degrees steady, drops a few degrees in the night to about 79. Humidity is low but j have added a humidifier and it stays steady around 45%rh.

 

[Shaggn]

At half strength i'd lower it to 30" might even be able to go 24". I'd try pH 5.5 for a little bit. I grow in coco and for some reason mine are happy if I drop it that low. The pH rises as they consume the nutes.

 

[Camden]

Okay thank you! I'll try feeding them tomorrow with a 5.5 ph and ill drop the light. I think maybe 3 of them are too far gone but possibly I can save the best looking one in the first photo?

 

[Camden]

Just to clarify you think the 550 ppm is okay for plants this size?

 

[Shaggn]

You have nutes mixed up already? adjust the pH and give it to them now. Run enough to get a good amount of runoff. Then after take the cup and motion it downwards to get excess moisture out, over a container or something

 

[Shaggn]

How big is the container of nutes you've already mixed. You could add some water to dilute it more then pH

 

[Camden]

I do have nutes mixed but I am running an 18/6 light cycle and the lights just went off an hour and 15mins ago. Should I wait till 6am (I wake up for work anyway) and do it then or will exposing them to light now not add more stress

 

[Camden]

I only mixed a half litre as I get a lot of runoff out of these small cups from just a little water but I can always mix more if u think a more thorough flush is a good idea

 

[Shaggn]

I can't properly answer that lol. I turn my veg light on whenever I decide to do some work. I don't do that in bloom ofcourse. Never had any issues. You could wait but they do look hurting a bit

 

[Camden]

I will dilute it more and try to bring it down closer to 400ppm! Great idea

 

[Shaggn]

No flush, add more water if you think the nutes is to strong. I don't go by ppm. sorry If it's the pH going to high then you need to get a lower pH into the rootzone.

 

[Camden]

Okay I will do it now, its painful to see them struggling!

 

[Shaggn]

I do my seedlings under t5. They don't get to go under the big light till they're big enough.

 

[Shaggn]

If it's pH or nutes to strong, they will be standing looking better by tomorrow night. Things happen pretty quick in coco

I'd say a mix of both, is your issue. They're a little young to be giving nutes.

 

[Camden]

Thanks for all your replies!
I will look into getting the t5 as the hlg does seem like a bit of overkill at this stage.
Sounds good, keeping my fingers crossed for tmrw night.

I gave them 480ppm at 5.5ph and will do the same again tomorrow

 

[Shaggn]

I'd give them straight water tomorrow pH'd ofcourse. Alternate till they are growing and have recovered. I'll check in on you here.

Btw Welcome to 420!! A lot of very valuable information and the community is packed with kind n helpful people!!

sorry edit i read you buffered with cal mag , but what else did you soak with , its meant to be calmag so the excess (K) is removed ) this might be the problem

 

[NuttyProfessor]

I started by soaking the coco in cal mag and seed & root nutrients ?
