I don't see any perlite...what kind of light is on that, looks like over fert + over/under watering on top of it, looks like that soil (?) is very moist... with no perlite you don't have to water as much as the soil will hold in water more....

EDIT: Also blackvelvet aka sproutco has killed many peoples garden I would set on ignore.

Did you mix dolomite lime into your soil mix? Grow big has very little magnesium and no calcium.

 

[chris1315haze]

no i didnt use any dolomite lime. is that important? those pics on there are from 2 days ago and now the plant has gotten alot worse. the leaves are becoming crispy,browning,dying and shit. for some reason though, the stem hasnt been affected at all. i flushed my medium yesterday to try and help but it hasnt.

 

[chris1315haze]

here is an updated pic of my plant now.

dead plant syndrome...

Dolomite lime would be a cheap way to give your plants calcium and magnesium. They need alot of these 2 elements. Grow big really lacks these. No problem though...read the following I posted for someone else recently:

You need to adjust the ph of your fert water after mixing and also test ph in your soil mix. So, you at least need some ph test strips in the aquarium section of a petstore or a brew your own beer/wine store. Ph range 4-7 is ok. Better a narrower range around 6.

How to test soil ph: After watering/ferting till runoff, wait 30 minutes. Apply a small amount of distilled water to the pot surface till 1 or 2 ounces of runoff occurs. Catch this on a saucer. Test this ph. If after watering/ferting and waiting 30 minutes you can tilt the pot and get some liquid out, you can test that instead.

You would use powdered/pulverized not pelletized dolomite lime. You can only use this if your ph is low. Adding lime when the soil ph is ok will cause problems.

If ph is low, you can surface apply the lime at 1 1/5 teaspoon per gallon of soil mix. Water in.

If ph is ok or high, you can add cal mag to your fert by using 1/4 teaspoon powdered gypsum and epsom salts per gallon of water along with the regular fert. Calcium nitrate could be used instead of gypsum at the same rate. Calcium chloride sold under names like tomato blossom end rot stopper could be used instead of gypsum. It will take the % ca and net weight of the bottle to give you a rate of 60 ppm ca. Calcium chloride and calcium nitrate are much easier to disolve than gypsum. Easily disolvable gypsum you can find at brew your own beer/wine stores.

Edit: Well now...those went downhill in a hurry. Keep these directions and include dolomite lime when you plant.

blackvelvet, what do u think is wrong with my plant in the last pic i just posted. is it overfert?

 

[Blackvelvet]

You said you flushed with plain water, right? Did you add back ferts? I would suggest using only about 1.5 teaspoons grow big 6-4-4 per gallon of water and include calcium and magnesium if needed.

Things don't look good. If they die, try to learn important things from this like needing to include dolomite lime/cal mag and testing your ph.

 

[chris1315haze]

yes i flushed it with plain water and i did not add any more nutes b/c if its overfert, i didnt want to kill it even more. i dont think it flushed out very well b/c i had it in a miracle grow/topsoil/vermiculite mix.

 

[Blackvelvet]

Does the miracle grow soil bag say "feeds for up to 3 months"? If so, you will never get it all out. Next soil mix include alot of perlite not vermiculite and powdered/pulverized not pelletized dolomite lime at maybe 2 teaspoons per gallon of mix.

I would ditch the miracle grow soil and get some Foxfarm or promix or something ( do a search on good soil mixes). I also agree with Kinderfeld. Your next soil mix could benefit from perlite so the soil doesn't hold so much water. I'm guessing you didn't start the seed in that same mix as it seams it would have died along time ago. Looks like an overfert to me. I bet your ppm in the runoff is high. Hope you get it all worked out.
Peace, Mr.M
edit: I notice you transplanted once about three weeks ago. Is that when the problem started or was it after you added the extra ferts?

 

[Guest]

Yup that's been nute nuked. I agree that your mix is too moist too. With the miracle grow soil you really shouldn't add any nutes until the plant tells you it needs some. I would tell you to flush again but with your mix being so moist I think now that it's flushed the best thing for it is to let it dry out a bit. With a soil mix like you have I'm betting the plants have been chronically overwatered also. Next time forget the miracle grow, forget the vermiculite and definitely lose the topsoil. Do some research on different mixes or get a bag of high quality potting soil that has no time release fertilizers and an equal size bag of perlite and mix the two. For this crop though cut back on the watering and cut out the nutes entirely until you see if they recover.

yes the problem started after i added to much fert/water at the same time but not until like 2 days after that which i thought was weird. but anyways the plant now is dead so i ditched it.
