32 Days Veg..Stunted? (PICS)

[jjf1978]

FACTS

Soil Medium: Miracle Grow "3 Months, Time released" potting soil - .21-.7-.14
Lighting: 150w HPS + 2"x2" 4 bulb T5 fluoro
Growth Stage: Vegatative
Light Cycle: 18/6
Temps: 86-90, average of 88
Strain: Sativa bagseed
Nutrients: Only fed once with 24-8-16 at 31 Days old (2 days ago)
Age: 33 days

PROBLEM

Plants are 33 days old and they seem small, minor secondary inter-nodal growth but nothing outstanding. The reason I am concerned is because a few months ago I had just 1 plant (as a test) under the T5 alone and it was double the size of the plants in question, although my memory does not serve me correctly and I do not remember how old it was at that size (my wife made me can it hehe). These three have been under the T5 alone and weren't really getting anywhere so I added the HPS, but it seems to have had no affect except to raise the temperature from mid 70s to 85-90ish. So then I added some light nutrients because the MG soil rating is only a fraction of a whole number...

I know MG soil sucks, I've grown in it before with the aforementioned plant with great results.

Am I being impatient or is something wrong. I am kicking myself for getting the MG soil again because I have a large un-opened bag of "Ez-Coco" ! I avoided it because I didnt want to have to regularly add nutrients being lazy, damnit.

I'm germinating some "Maui Wowie" as my 61 year old hippy friend (hopefully the seeds arent that old too!) called it. Some sort of sativa x hawaiin skunk mix. Anyway before I pop those babies in there should I be worried about the temperature? I'm growing in a closet with a black tarp fixed to the inside of the frame so there really is no way to ventilate it - it's gonna have to do, the only place my wife will allow it.

Any suggestions would greatly help! Thanks!

idk man.. their seams to be many nodes,, might be because the strain. do you know what strain it is?? good luck on the next!!

I'm not sure of the strain really. I know it is for sure it is some sort of Sativa. All the previous plants I've grown are with seeds from the same exact bag - I've had them in an air-tight mason jar for 7 months now, maybe that was the problem, how are you supposed to keep seeds? something I've overlooked?

 

[kindbud17]

ummm, idk about the seeds. i usaly dont save them verylong.. but if its sativa it might be stunted..? i would suggest some new seeds maybe.

Any other suggestions? Anything I'm doing wrong or just some bum seeds/genetics?

i really cant tell, by the looks of things your GROWING ha, but i mean idk a freash start never hurt kno body!! u could keep those goin, but yes i would try some new seeds

Yeah I am going to keep these going and see what happens. Maybe they are developing but I don't notice it because its all spread out between root growth, nodal growth and main fan leaf growth. They are growing though and look healthy so I'll just be patient and see.

the soil may have had a little too much nutes to begin with . By the looks of it there is some nute burn on the leaf tips but i may be wrong. Also i think sativas can be sensitive to nutes so probly best to wait till a few nodes tall to feed 1/4 strength

 

[lilmafia513]

lose the MG soil, install some exhaust, it's needed, and they got nute burn, probably Nitrogen toxicixty. MG already has nutes for three months, you dont need to give it any nutes yet.

MG soil is fine. I've used to myself with great results. Your issue is you used 3 month feeding soil from the start, so the plants were getting shocked with nutrients. The node spacing seems well so light is probably not a huge issue. I would probably guess a watering issue at first glance causing root issues so the plants energy has been going to help correct that and not simply growing or the soil is burning the plants. It could be seed genetics but if the others all grew fine then thats doubtful. Personally though I don't like waiting around so I would probably put them in a new soil, let them recover for a few days and then give them a nice dosage of nuts. If they take them and grow then thats great, if not then I don't want those little ones anyway.

 

[jjf1978]

Yeah it probably is nute burn, I added a little as a test to see how they'd react. The new growth looks good but I will hold off on the nutes for sure.

I do have an oscillating fan in there and I can see the stems strengthening - but yeah I need to figure out someway to pull the heat off the HPS...this will take some thought during the boring commute to work!

without supplemented co2, mj just about stops growing at 85 degrees and up

I have that Ez-Coco soil, should I remove them from the MG soil over to that? As you suggested I can let them recover for a few days, see that they are growing again and then add some nutrients. I'm just worried about putting them into shock when transplanting and further slowing their growth.

Yeah and locked in the "tent" of a closet isn't helping the CO2 concentration. I have some activated yeast and sugar, was considering putting together a home-made CO2 jammy. You think that will make a significant change. I'm going to try and I'll let you know

You need to get that hot air out and fresh air in. Opening the closet door will let in air, but hot air doesn't do anything but get hotter and take away oxygen.

I would still give them a good flush to get the Extra N out of them, before giving them any nutes after a transplant.

 

[FLoJo]

it will but fresh air is gonna do more good than using yeast.. id get a co2 tank and reg and pump that bitch up and they will thrive in those temps

I'll have to work on an exhaust solution. I have an exhaust fan from a previous grow. I wonder if I could hang it right next to the HPS hook up the flex ducting and cut a hole in the drywall and vent it into the space between the studs? I can leave the closet door open to let fresh air in. Is this a plausible solution?

Too hot, shitty soil, no need to feed for the first 4 to six weeks.
Transplant plants ASAP into FoxFarms Ocean Soil, use B1 Fertilizer.
Use the biggest pots that fit your grow area. Flush your soil with aged
water, check your PH, every month with a very week solution of ferts.
Make sure you have damn good ventilation. Good Luck Bro.
