need help, sick ww and mli's

[TheBlazer]

Well a quick rundown.
This is my second grow, first one did finish but with a very small yeild.

I am using a rubbermaid tub, 30gal, with 7x26w clfs. Have 3 2"pvc elbows for intakes and a 120mm computer fan for exhaust.

I am growing 1 feminized White Widow plant-sprouted 3/25; 2 Maple leaf indicas-sprouted 3/24; and two more MLI's that sprouted on 4/2. All from seeds.

Temps are around 77-84 depending on the time of day and 73 when the lights are off. The humidity is around 25%

They are also on 18/6 lighting right now, all plants are only hairs away from the lights, as close as possible without touching.

I am using bottled water and the ph is 6.8-7.2. Also just added a jug of epsom water with 1/4 salt to gal of water. I have drainage holes poked into the bottom of the cups and only water about every 4-5 days unless the cups feel lighter earlier.

Soil is made up of 3/4's regular potting soil, 1/4 perlite on the older ww and mli plants. 1/2 potting soil 1/2 perlite on the two younger mli's.
The plant in the 6" pot is in mixture (all this is per gal)1/2 potting soil, 1/4 perlite, 1/4 vercumulite, 2 tbls bone meal, 2 tbls blood meal, 1 tbls dolimite lime.

Well my problem is how come these aren't growing . I look at other plants and even my first grow and these plants should have been much bigger by now.

I did have a heat issue were the box was getting around 90-93 degrees but I fixed that and for the last three days the temps have stayed under 80 for the most part. I tried to put a humidifier under one of the intakes to bring the moisture up but it's not helping any...plan on buying a cool mist humidifier on monday when I get paid.

Heres some pics all taken today. I have a shitty time taking pics so excuse the quailty

This is the one of the older MLI's. I am gettin so frustrated I just put it in the 6" pot with the new soil hoping it would fix itself up...did the transplanting on 4/9 and watered today with 1/4-gal epsom salt.





Here's the feminized White widow. She ended up touching the light so two of the leafs got burned off, I trimed them up though.



Other MLI that sprouted 3/24



And the youngest MLI's that sprouted 4/2. They are pointing upwards, won't pull out of it.

Think the whole problem was the heat? these baby's haven't seem to have and growth in awhile now and they just keep lookin worse

Help!

In my humble opinion,

Too much food. Never been a fan of adding epsom to my water either.

2 tbls bone meal, 2 tbls blood meal, 1 tbls dolimite lime in a 6" inch pot and I'm surprised she's still alive.

I would flush the heck out of them.

 

[Core]

mmmmh you got a few problems if i read this.....i'l try and help as much as i can my friend.....

verry important ! you must lower the ph for soilmixes to 6.3 - 6.5
and aslo for the pots that consists 1/2 of soil its regarded soilless and needs a lower ph range 5.8 -6.2

raise the humidity but you already knew that...try 2 add a little bowl with plain water in the rubbermaid or a wet piece of towel 2 raise humidity...those temps would be ok for MJ she can handle that....

next i suggest not adding any nutes or epsom for a bit ...they dont need food when they are that small.... just some rhyzotonic for rootdevelopment

ohw and just feed them 20 ml water at a time... soils looks way 2 wet imho

and i think there not growing coz they are stunned ...you have 2 many problems and that is the cause.....
wel here ends my knowledge...i tryed
GOOD LUCK buddy

 

[stretchpup]

Oh, per gallon.

Still, sounds like a established food mix, not a seedling mix. I would put my transplants into a mix like that, a few weeks before flower, not seeds.

I bet the roots are thinking HOT HOT HOT HOT when they try to grow....

Flush and go much lighter.

Put seeds into a plain medium until they need food. They can and will take a little abuse if you miss a feeding, but won't tolerate a burn as much.

I cant tell you if this is too strong. The guys in the organic section like Suby can though. I can tell you your missing potassium and micros. Seaweed like maxicrop might be something neat to add to your fert plan if your trying to grow organic. Vermiculite really retains too much water for indoor use. Better to have to water more often than let a plant sit in soup for days. Water till runoff occurs then allow to get quite dry but not wilted. Ph needs to be lower. Seedlings cant live on just water forever. Once true leaves form, begin lightly ferting unless the mix has ferts added at planting . (You don't add ferts during the cotyledon stage to prevent excess stretch )

I usually use just 1tbls of bone and blood meal per gallon, 2 per gallon sounds way hot for seedlings. The potting soil should have everything the young seedlings need for the 1st 2-3 weeks of their lifes. Then go with a hotter soil mix.

 

[Guest]

With that much stress at such an early age have you considered just strating over ?

 

[Nikijad4210]

I have to agree, the bone & blood meal amounts sound way too hot for seedlings. I'd always read that as a general rule of thumb, only 1 tablespoon of each (rather than 2) was to go into each gallon of soil/mix. And they certainly don't need fed when they're that young, either. Generally, seedlings need food after about 2 weeks, but only 1/4 strength to 1/2 strength MAX of a full dose of food, and no more than that.
Also, the PH is WAY too high, the optimal range for soil PH is 6.3 to 6.7, I believe. And anything too high, or too low, is going to result in nute lock-out, PH burn, etc. Always gotta try to shoot for that optimal range.


In a nutshell, you're basically killing them with food they didn't need. Not much to hope for in terms saving them. Junk them, start over, and pay close attention to PH ranges, and feeding schedule advice for a starting point. You'll learn more as you go from there.

not only can you not tell if its to strong You really cant tell this guy or anybody else anything good. Your out dated text books dont grow cannabis. I thought we all went over this stuff a few months ago. Sproutco/hotgurl/stonewall/blackvelvet. You belong in a classroom teaching the essence of botany not on a message board guessing peoples problems. Infact I will say it again This guy DOES NOT GROW CANNABIS. His formulas come from some internet aquriaum calculator and a text book. Not only do you confuse people you pretend to be a cannabis grower

 

[TheBlazer]

Thanks for the replys everyone.

Sorry I ment 1 tablespoon of blood and bone meal went into the mixture. Also only the plant in the 6" pot is in that, the other two are in just regular promix potting soil and perlite.

The only plant that got the epsom salt was the one in the 6" pot, the otherones all got straight water.

I was really considering just junking it and starting over, as I still have 3 feminized ww seeds and 5 more of the MLI's, but I'd really love to save these if I can.

Is 1/2 promix 1/2 perlite too strong of a mix for seedlings?? That's what I used, I just transplanted one plant to the new mix to see if it would help.

I will have to get a new jug of water for the next watering, the ph was around 6.4-6.6 but I thought it had to be closer to 7 so I added tapwater till it got there.

Also does anyone think this is too much lighting?

 

[TheBlazer]

If I do start over what should I use for my begging medium? Just the regular potting soil, it's the promix stuff, or should I add the perlit again?

That's all that they were in and they are are doing horrible .

 

[Core]

well promix is 2 hot for most seedlings ime....try a lighter mix ....and promix is a soilless mix so you should aim for a 5.8-6.2 ph..and if the bags dont contain perlite you should add it

 

[stretchpup]

plain mix with no shit added.

core i know you're thinking of FFOF,

promix out of the bag is clean, plain, and has no nutes.

(it's STILL not as nice as coco but that's another thread)

Blaze, if you start over use plain potting mix. anything- schults seedling mix, whatever, just dont add nutes for literally the first couple weeks, just spring/distilled water.

when the seedlings are working on the 3rd or 4th node, you'll see it's time to feed... (sometimes sooner)

like your pics you posted. they should be on only water until that point.

 

[TheBlazer]

-update-

I got a cool mist humidifier and managed to get the humidity up to 35-40...bettter then nothing I guess.

I got some spring water and the ph is about 6.4 so I'm gonna stick with that for waterings.

The mli I repotted is looking awsome! Made me decide to repot the ww, two days ago actually and she is already looking better. But the other three still look like crap..

Here's the mli



The ww, grew a few new leafs but still isn't shooting up like the mli



And the rest, still looking crappy




I didn't mean to say I used promix (someone actually had me under the impresson that any regular potting soil is promix.) It was just plain potting soil and perlite.

I'm really thinking the whole thing was heat as they were in the 90's-93ish range for the first few weeks of their lifes. Untill the around the 12th when I posted. Maybe I'll try to save the bigger mli and the ww and give up on the other two and start over.

Damn heats a bitch, spec with summer creeping up.
