I have just started growing and am new to all this, but started with auto flowers after being told they would be easier to manage, i have 3 strains (Exodus Cheese, Gorrila Glue & Moby Dick) on the go and as stated in the heading they are just now 2 weeks old from seed (so until now no nutrients have been added, all they have had is ph’d water), they were brought on under a T5 and am just now ready to switch them to CFL, but have noticed a strange issue on all the plants leaves, they are not losing color like most nute defiency would show and am curious as to what could be causing the issue and how to resolve it, they started seed life in root riot block until they had established a reasonable tap root, then was planted in 1 liter fabric pots with coco loco, all seemed fine at first but now the leaves are just drying up and dying off, any help would be great as i dont want to lose them all
Exodus cheese

@AngelicSoul thanks for filling that out. And no worries. Even though we aren’t from the government we are still here to help!
Is this your coco loco?
That is it, yes
ok, As you have already figured out this is a great soil mix! It can be a little finicky for first time growers though! pH 5.8 is where you need to put that water in. If it came out 6 last time put in 5.6 Also make sure you adjust the pH after you add nutrients as nutrients will affect the pH.
Have you used any nutrients?
Also i’m not a “Soilless” Grower… but I’m gonna hang with you until someone else more knowledgeable comes along.
Can you take a pic of at least one of your plants from the side so I can get a feel for the node spacing etc.
Also how long has it been since you watered them?
Thanks Bob 
They got flushed this morning with 5.8 Ph water because I was advised by someone else that they could be nitrogen toxicity… Prior to the flushing they were only watered with PH water 2 days ago… I have not used any nutrients as of yet… Just ph water is all they have had thus far
This picture was from last night
ok, coco is tough to tell from pics if it is wet or dry lol! Flushing is a solid move and won’t hurt a thing.
They look pretty healthy otherwise. i’d say the lights are right.
my inclination is that they need nutrients… but like I posted earlier, coco is not my deal.
@Donaldj @Hawkeye_diesel I know you guys are into the soilless stuff
My guess is that the very high pH for your medium is locking out almost all nutrients. If you look at the scale, only nitrogen and magnesium can be absorbed into the roots in a soilless medium at 6.5 ph
they were just about to start nute’s at half strength for a week then moving on to full strength the week later, but when someone said possible nitrogen toxicity caused by the bat crap in loco i was cautious to add anything until seeking advice from here as suggested by the same friend
Because coco loco is neither solid coco or solid soil its a 60% soil 30% coco 10% who knows what with some perlite… but point being because the medium is mixed i have been aiming for a solid 6.0 to try and accommodate both mediums, i know 6.5 is high and was again told that could of been caused by the nitrogen in the loco mix as i had only been giving them PH 5.8-6.0 water whether by feeding from bottom or foliar feeding with a touch of AN Cal-Mag pro,
am at my reply limit for today so adding here… the ph drop was done 2hrs ago under advice, and whilst i was not giving nutes the bat poop is loaded with nitrogen, will get a close up pic for you now of the contents because like you i could NOT find anything online about it and just saw coco coir on the bag front and grabbed it as i was told that coco tends to be more forgiving for new growers
Thanks Bob for all your help and your quick answer back to me… I will make sure my ph is at 5.8 and I will keep ya updated how it goes… thanks again
I will def start a journal as soon as I can post again :)) seems there will be a lot of useful info around here
IMO @AngelicSoul It’s not toxicity its deficiency!
Toxicity is from too much nutrients and the pH you had would not low for the roots to absorb nutrients
How long ago did you get the pH down from 6.5 to 6?
Could you post the ingredients in the coco loco? Pic of the bag or whatever. I looked online but I can’t find the exact ingredients
Dolomite Lime (for pH adjustment) see here is the kicker. The dolomite lime probably brings the pH back up to 6.5 But with all that flushing you have washed that away, I’m pretty sure.
At some point when enough “stuff” (extremely technical language) is added to soil it ceases to be soil and becomes a “mix”. In the case of a mix I believe you go with the 5.8 pH. BUT then you add dolomite lime… back to 6.5… and then we flushed that all out… 5.8 again is where you should be. That’s what you want to get out of the runoff.
ok. The damage to the leaves is not going to get any better. Watch the leaves closely to see if they get increasingly worse in the short term.
(Gotcha on the limit) Reading other posts and liking them adds cred as well!
ok @AngelicSoul I’d like to encourage you to start a grow journal here! That way you and the other members can stay in touch!
Here is the link to start a grow journal. Just “+ New Topic” When your ready to start one if you decide too! Or you could actually move this to the grow journals, adjust the name a little and keep going from here, your call!

Your girls are going to be just fine! A little adversity is great for them in the long run (Topping, fimming, super cropping)
Welcome to ILGM @angelicsoul - you came to the right place, these folks here are very generous with their knowledge and support.
Happy Growing,
It doesn’t look like toxicity quite the opposite Coco is like hydro your plants should be fed lightly every time you water lightly. The Ph levels Bob suggested are correct and the older lower growth is showing the deficiency because the fresh growth is feeding off them I would suggest feed feed water, or simply 1/4-1/2 dose feeds every water coco doesn’t retain nutrients like soil it rinses clean out and if your plant is 4-5 days between water cycles she pretty much goes hungry
Ok firstly these are just my opinions and views not meant to offend anyone just trying to help a strange issue
so 1… coco loco is NOT just coco, its a hybrid mix of top soil scrapings about 60% and 20% coco with who knows what else, meaning it retains water reasonably well unlike my favoured Pro XL coco,
2… coco loco has bat guano in it meaning its actually quite high in nitrogen right out of the gate…
now for me personally and this is just my opinion, if the plant was suffering with say a nute deficiency then wouldn’t the leaves be turning yellow not just drying up and dying off?? whether that’s a nitrogen or potassium or phosphorus, same with magnesium and calcium they all result in pale yellowing leaves, not something I see in these pics,
Bob mentioned earlier how healthy the plants look apart from the drying up issue, they look APPARENTLY healthy because they are loaded up on nitrogen from inside of the coco loco, a seedling in my own experience is good for 2 weeks with just water feeding and the occasional misting of say formulex or very mild maybe 1/4 mix of whatever feed your using, for me personally I think these plants are overly green and dark for their age, a lil yellowing from say lack of feed would be the norm for a 2 week old plant for me if you was just using coco,
Either way I would say Either Nitrogen toxicity which will be solved by flushing them out and keeping PH at 5.8 to 6. with a run off at 6.2 being acceptable… again specially if your just using coco without the loco…
the next logical would be Bobs high PH causing nute lock out, I don’t think it would happen at a ph of 6.5 though, but then again I can only answer from experience and only use coco perlite mix 90/10 but if bob is right and they have tweaked and gone into lock out that’s going to be solved the same way in essence, flush them get the ph run off down to an acceptable 6.0-6.2 and that will slowly fix the issue,…
but I do NOT advise on feeding them yet, they do not look hungry to me personally they look healthy because they are exceptionally green, continue with flushing them through with water as they beginning to dry off, make sure the PH is stable at all times, and when you start to see the leaves lighten in colour a little then get them onto your chosen feed schedule…
hope that helps some
@ Angelic you can judge for yourself
Nitrogen Toxicity
Problem: Dark green leaves, weak stems, and overall slow growth. Marijuana leaves that are nitrogen toxic often get “The Claw” or talon-like leaves that are bent at the ends. They also do an odd curving (or cupping) that is often mistaken for overwatering, but is unique to nitrogen toxicity. You can see a “clawing” leaf pictured to the right and more pictures below (click each picture for a close-up).
Leaves that turn into claws often start turning yellow and dying if the nitrogen toxicity is not treated, much like a nitrogen deficiency, only the leaves will continue to get more and more clawed. Leaves eventually turn yellow or brown and fall off. You can tell if yellowing is caused by too much nitrogen because the rest of the plant will be dark green, and the yellowing leaves will turn into claws first.
I know guys that are using full nutrients in FoxFarms soils and none of them are showing any signs of excess or deficiency.
So what is your solution? @B345T I’m happy to step back and let someone else guide.
my solution much like yours @bob31 is to get that PH run off down to 6.0 to 6.2, everyone has their opinions personally for a new grower I would advise not using coco loco again its loaded with hidden nutrients that cant really be accounted for, and also as bob pointed out dolomite lime which is going to mess with the PH, go with a straight coco perlite, nothing added, for now give them a day from when you flushed them and then check the pot weight its always a good judge if they are hungry or not if the pot is light then they are hungry if not then they don’t need anything yet, obviously if you change for future grows to coco then like bob and Donald both mentioned you will need to stay on top with regular feeding because coco dries very fast,
but for the time being flush and watch give them 24hrs at least and hopefully they will start to perk up the bottom 2 sets of leaves the first single ganga leaf and 2nd set of leaves are shot they aren’t important chop them off they cant do their job so are dead weight, after 24hrs do the same again top feed with PH 5.8 water and wait for a small run off to begin. check that PH anything under 6.2 your on song, again leave them for 24hrs hopefully by then the leaves will start to pale up a little because as I stated they are awful dark for such young babies, once they start to pale then start feeding tem post pics here ever 12-24hrs keep us updated because I do believe if I’m wrong then bob is right and if bob is wrong then I am right which ever issue it is they can both be fixed the same way just flush and get the ph right then and only then start adding nutes again
My Girls Both healthy and notice slightly pailer 4 weeks before being tripped to flower
The same 2 girls 5 weeks into their flower now
