I have another SkunkxHaze seedling growing with the same soil and water and it seems to be going great. Any help would be appreciated.

Foxfarms is really acidic soil, did you add any dolomite lime while mixing your soil? The dolimite would fix ph, mag and calcium problems. Also 50% perlite seem to be a hella lot of perlite, but I don't know if that affects your soil negatively at all.

Looks like ph there, that’s what mine started out like and just got worse until I figured out what it was.

This what she looked like after a while...




Hope this helps at all.

I'm leaning towards ph spotting. My PH out of the tap is 7.4 I figured that the little bit of NPK would balance it out to around 6.5 for a little while till i got some dolomite. Maybe it dropped the ph too low or maybe it was a shock or something.

 

[halloweed2006]

AinSophAur, in organic soil if you add nutes (depending on the brand) it can lower the ph even lower, making the soil very acidic. You need to get some type of ph up thing very soon or else you're poor little babies are going to get really stressed.

totally agree. soil here and i start w/7.1 ph. nutes drop to 6.2. i up it to 7. run off, iuse lime to buffer also, 6.8 ph. i use meter. .5 degree down swing n soil means ca lock out which causes mag def...and so on.

 

[AinSophAur]

So i just got back from the hydro shop and they are out of dolomite lime and will only receiving more thursday. So im without lime till then. I just waterd her two days ago so the soil is still moist. What should I do? Would a good flush help her or should I just let it dry out?

wth, fox farm is NOT acidic, it's pH adjusted to 6.3 to 6.4 that is around the normal area you want the pH to be for soil growers.

What kind of food are you using?
How much is half strength, how much food to how much water mixture?

Your plants are hungry dood with your water being near neutral it's going to be a little soft you would not have any pH problems if you were using plain water in FF mixture.

It's hungry for food and if I were you I would get a different kind of food. the spotting ]like that is phosphorus and it's also hungry for nitrogen as well; but the food you have is too high in nitrogen and will buiod up too quickly...... get a different fert to use and feed every 7 days.

I presume the plant as been in this mixture since seed?

this has not been mine or many peoples experiences with FF soil. IT needs dolomite lime or FF POM added when mixing your soil. Just check out the MSM thread to see other people with the same problem.

FF soil is primarily peat based which is very acidic, they may add some clamshells or something but for many strains it's not enough. God I hate disagreeing with you Stich, you're like my idol THank you for everything you've done on these forums. /me goes back to corner

everyone allways forget about foil spray
have you tried to foil spay them? when the roots get locked out i feed thru foil spray.

 

[DIGITALHIPPY]

the shitty ass tap water is to blame.

ph sucks and probably has 500+ ppm CAUSING lock-up.

im a ffof fanatic and ive got no issues with straight ffof on seedlings. ffof + RO = happy plants.

the light color of the leafs sugest they want more nitrogen/mag the ridged sides sugest they want more mag aswell as P, i bet the burn hole if from k def because of ph/tap water lock

Perfect for containers and ready to use right out of the bag. Ocean Forest® is pH adjusted at 6.3 to 6.8 to allow for optimum fertilizer uptake. There’s no need for nitrogen fertilizers at first; instead try an organic blend like FoxFarm Big Bloom™ Liquid Plant Food to encourage strong branching and a sturdy, healthy growth habit.

Hey hallow, do not feel bad for disagreeing with me I am human just like everyone else is

So for people to disagree with me, I don't want people to fear telling me I am wrong, I am human and make mistakes too and I make them sometimes if I mis read something incorrectly or information was not given; so dude don't you feel bad not one bit!


I have never seen fox farm be acidic since it has lime already in it which was why I was trying to say what I said........

I will have to agree with digital; those ppms are outrageous and should be getting some different water supply for those plants as well...... but also they look hungry to me too. but change water and get some nutes

 

[AinSophAur]

She started out in a 4" and just recently transplanted into the 8"
She quickly used up the nutes and started to get hungry. This is when i fed her with some 30-10-10. Then the ph spotting and lockouts started comming out.

To be safe i flushed her good and then added a bit of dolomite and picked up some Floranova grow and gave her a small dose. I will check on her tomorrow and take a new picture.

 

[AinSophAur]

Here she is one week from the previous picture. Looking a bit better. She's droopy from the flush and feeding but should perk up when the soil dries out. Should I feed with every watering now? I went half strength with the floranova.

My plants look very similar to your first pic

How often are you watering your gals?
I would never feed every watering..... the best way to go is once a week, if you have to stretch waterings out too far the plants are in too big of a pot, just a future tip not saying that is now.....

if you have to feed every watering you should water every 3rd feeding, just plain water to flush out any excess or unused ferts in the soil which cause nutrient problems.....
