Common WHITE WIDOW faults? SLOW FLOWERING

My WW is about 5 weeks into Flower, but have been very slow with bud growth. They DID however, just stop stretching.
I was very sick in bed for a full week, and would love to give them a goost boost.
Maybe some superthrive? Molasses? I also have the FF trio, and other basics.
But they look healthy to me.

Bueller?....Bueller?

My WW has stretched more than one of the pure sativas I'm running. I've noticed they seem to suck down mag in copious amounts. They are the only strain I'm running that is showing signs of serious mag deficiency. Could be the ph too though since my meter has been acting kinda wonky. I'm not really impressed with it.

Whose WW is it? I'm running Greenhouse Seed Co. WW

What is your setup anyway? My WW's are at 5.5 weeks and they have 3 times the size of bud. I'm running 1000 watt HPS though so that could be why?EDIT: Just looked at the pictures more closely and my WW's looked like that at just 2 weeks of flower. Photo is my WW @ 4.5 weeks

250 hps, and 4 23w 2700k cfl's. The HPS is about 10" above the highest plant. CFL's are for the lower parts.
I just expected more growth this far but first time with ww.

NO ONe can offer any help?

Who's WW are you running? That's such a generic name for a strain now. The plant in those pictures looks more like a Thai/Sativa type of deal. Very, Very fingery leaves and very very stretchy = Sativa!

I got them from cannaibisseeds.com
ordered a bunch of feminized ww. So far all females, and they grew great right up to this point.
Hoping they will take off any day now.

Looking for a couple hints on what I could get them going with.

I am not very familiar with cannabisseeds.com, but they don't seem to use any other reputable breeders. Your plants are just very Sativa Dominant...VERY....If they stretched for 5 weeks, I'd expect at least a 15 week flowering period and I think that's what you are looking at. It feels very far behind, but it's likely right on schedule. There's nothing that you can really do to speed it up, just ride it out and they will continue to grow. The genetics have told the plant to take it's sweet ass time.

Hmmm, they do look a little behind schedule even for a sativa heavy pheno. What else can you tell us about your routine? Watering, nutes, light cycle, i.e. The first thing I would do is hang out in your grow room for a minute or two after the lights go out and check for any light leaks. Even a red light on your power strip can stress them out if it's close enough. You should also invest in some flowering nutes, just be careful with the FF line on your first watering. I would go 1/4 strength/

Yeah I run 12/12. On a 9am and off 9pm. I have a very minute light leak and it is not my slightest concern. It's been there since the start and the plants deal with it.
I use 3 gallon pots with FFOF/20% Perlite mix. I must confess when I first bought the FF trio nutes, I used full strength of the HYDRO schedule (didn't realize it differed for soil as that sched didn't come with the nutes).
It severely stunted the growth/stretch of one of my 3 ladies. The leaves burned, took forever to start growing again, and is currently 2 FEET shorter than the other two girls.
Im currently using 1/3 strength of the FF chart and I'm on week 8. I usually water each plant with about 1.5 gallons every 5 or 6 days.
Should I be able to go to half or 2/3 strength? Also, Each week, just gets one dose correct? I

perhaps you should also lookin to adding CO2 in to your room. Dry ice or dispenser is a easy way to do this 3 time a day for 15 min.

While co2 would def help, it shouldn't be needed to get these ladies moving.

Is it too late to use a little superthrive.

They are overferted and Sativa Dominant. I'm telling you, there's nothing you can do or add or change that's going to speed things up. It takes as long as it takes, wait it out. The plants usually stretch for the 1st 1/3 of their flowering period. If they stretched for 5 weeks, they'll take about 15 weeks to flower and that's not abnormal.

Marijuana can "deal" with a light leak by taking 15 weeks to flower. If you have a light leak you should patch it up, as it can lead to a hermie in the future.

Why are you on week 8 of the FF feeding chart if your in week 5 of flower? I'm guessing that's from the beginning of veg? I would stay on the mid-flower feeding schedule untill the progress a little.

I'm not sure how big your ladies are but if they've been ok on 1/3 strength, try bumping it up a little. I've had problems in the past with FF nutes with nute burn and nute lock. When I feed I always like to do a small flush before adding nutes. So, for a 5 gal pot I water the first 4 gallons regular ol' water and add the nutes on the 5th gallon. FF will also chang the ph so make sure your checking it and adjusting after nutes are added.

Week 8 is only the 4th week of 12/12 schedule. So I'm right where I need to be I think.

A very minor light leak has been there since day 1. Definitely lees than a crescent moon would ever produce.

I just noticed a few fan leaves have a bunch of tiny brown spots. Only see it on one plant, on about 3 leaves.
When I potted I used a small mix of granular and fine lime, so that should remove a couple things from possibilities. I forget how much I used but I researched it first. It's all written down in the room.

Good call on the dolomite lime, should give you plenty of calmag. Brown spots can be the beginning of nute lock or a fungal infection. Do you have sufficient air flow in the room?

I have a dual window fan blowing from down by the pots, up into the light. This also hits the ladies.
I also have a 6" oscillating fan that blows across the top 1/3 of them. It's a sealed room, but the door is frequently open for hours at a time every day during the light cycle.
My last 2 waterings have been straight water. About 7 gallonns or so per 3 gallon pot.

I've grown a lot of WW's, and not one has ever had that pure sativa leaf structure.....I'm thinking it isn't what you think it is.

I wish people would throw away all those cfl's that are meant to light you living room with and get some real lights....so much time and effort for such little to show for it. I feel bad people go through this.

My primary light is a 250 hps. I just use 4 23w cfl's for a little extra light on the sides.
