1 Month Old Need some help

[indicapimp]

Lighting 2x600
Lamp height 16 plus inches
Temps 78-86 7/24
Soil Type 5x5x6 inch sq. container
Tap water PH 7.1
Half Mushroom compost and half FFOF/course Pertlite
Feed with fish emulsion one week ago and yesterday (Entire crop)

First pic was under an outside air vent which got cold at night?

Second picture: I AM MORE CONCERNED ABOUT I HAVE SEEN THIS BEFORE AND IT IS A BITCH TO CORRECT. It is the plant that is turning yellow on the outer edges. This plants were need the fresh air intake also...


What I do not get is this is the canopy and most plants are doing fine...

thanks

Hi IP,
That doesn't sound like a very well draining mix and waterlogging surely deprives roots of oxygen and stunts growth. That would be my diagnosis of the first plant.

The second one looks like it's leaning in a mg deficient direction. I'd give epsom salts up to 1 tsp/gal though many people use calmag. But if it's in the same soil mix...it's probably not that simple.

When you up-pot (and I'd recommend soon), be sure to use a more balanced and well draining mix and maybe rinse off as much of the old stuff as you can. Perlite is the answer...

Sorry,
Perlite is was i am using, the fox farm (course stuff).....Would agree that MG deficient was what I was thinking. Thing is if the ph isn't right wont matter about the mg uptake due to it locking it out anyway. Can I test with a foliar feeding over the weekend with a 1/2 strength cal mag supplement?

Was going to replant in the 34 day into one gallon containers since they haven't been sexed yet nor genetics straightened out yet. Was thinking half coco/half Promix to control uptake with fert's instead of soil???

IP.
So in your post...where you said vermiculite...you really meant to type perlite? Why don't you edit that first post and correct that since others will see that and think the same thing as I did.

Are you worried that your ph isn't correct? if so, definitely work on that. You can check your runoff water which will give you a clue.

Sure, you can try a foliar feed to see if the interveinal chlorosis on that second shot improves. I personally would use epsom salts, but if you have calmag I suppose that could be used.

So you want to try half coco/half soil? I have no experience with that. It won't control nutrient uptake...since coco has a high CEC it hold alot. But lets hope some organic guys chip in here. I'm a hydro guy.

NO Significant Change with 2 feeding of Epsom salt. I am going to transplant tonight...Just need to decide what to use in containers. Might just go with Moonshine mix...Worked on some Promix and Coco last night. Fucking hands are sore breaking that shit up...

IP,
This post set off a red flag. What were you "breaking up"? Coco brick? The bricks are meant to be soaked in water. They then expand to full volume and is much easier to manage.

Also, bricks tend to have a problem with retained sodium. From ocean water...since it ages out in the open, often on the beach.

So if you put un-prepared coco into your pots with soil...you may be in for trouble. Let us know what the situation is.

no worries...the 5 weeks old are waiting in 5x5x6 pots to be transplanted. Currently in FFOF/compost and pertilite. So epsom salt only added to original problem

2.) Well that explains why the fuck it hurt so bad Newbie... to this world in so many ways...It's just wrong!!! But working through it. Think Coco is the way to go....Think I will go half Moonshine mix with some young plant's in Rose Buckets; they appear to be Females. I want to veg them longer...
then clone
Next will play around with Coco with some males and see if I can them them trough transplant shock without killing them.
Second round with sexed Clones will go Full Blown Coco and see what happens...

IP,
Well if the epsom salts didn't help. then at least it was useful as a test. Now you know it's something else. Most likely a nutrient lock-out from the ph being out-of-range.

On the coco preparation: Soak the coco and get it saturated. Then put some in a large pot...water enough to get good run-off and measure the TDS of the run-ff. Should be the same as the water that you put in. Meaning it didn't pick up any sodium passing through the coco. If it did rise, then you need to flush the coco. Warm water workd best and lots of it.

Then before using the coco, it's best to pre-soak it. Some people just use 1/4 strength nutrients. Some use their own magic concoction and I actually believe there are some manufactured coco pre-soaks.

Then it's ready to use. Some expensive coco like Canna comes pre-hydrated and flushed and pre-conditioned. But generally bricks aren't. I used GH bricks which are high in sodium and need a thorough flush.

It's best to use Coco specific nutrients too. They are tailored to the nutrient retention profile of coco. Read some coco threads and see what people are using these days.
Good luck,
ET
