IMG_1935.JPGIMG_1928.JPGIMG_1934.JPGIMG_1927.JPGIMG_1930.JPGIMG_1923.JPGSo Im concerned about the skinny fan leaves and the tips curling down and yellowing a bit. I wasnt too worried about the lower fan leaves but but last few days seems to be getting worse. First time ever growing from seed. Its white widow using 4 4ft t-5s which are now all bloom spectum bulbs. Suggestions? input? thx Ive got a ways to go and I dont want to f it up now!
 
make sure to get a good fan keeping those leave moving rapidly, nice breeze, check your nutes, make sure you have it in a good bloom recipe, also make sure your ph is within spec. no foliar feeding, I think it goods good, just recheck all your nutes!!!!
 
Great job for your first run! What nutes are you using and what "bloom spectrum bulbs" do you have? You get the most help by putting as much info about your grow as you can, and pics really help also!!
 
Looks like a little too much nitrogen, that's why your leaves are eagle clawing. The yellowing/browning on the bottom is the start of potassium deficiency. Are you using a PK/13/14 booster yet? Around now is probably the best time to use.
 
Are you kidding me? Seriously now.

To the OP: I don't want to sound harsh or discourage you here, honestly, I want you to be able to do things the right way. Usually don't touch posts like this with a 10 ft poll.

There are quite a few issues here, this is not good... a PK/13/14 booster? :shock: For real? :wall:

Obviously there is some lack of preparedness here. This seems like the root cause of the problems, and many people have this issue. First of all the lighting you are using is not intense enough. Four tube T5's are great for starting seedlings, early vegetative and side lighting. This is more than likely why the leaves are curling as they are, and you can see some of the lower growth in the dark has wilted near the point of death (it might as well just be removed). Plants are stretching due to the lack of light, buds are evidently very airy.
 
man dont pay these jokers any mind man....

only thing said so far that is sound is that 4ft t5 bulbs arent penetrating to the lower canopy...

heres what i would do.

trim off everything under your trellis...and wait.

if your not feeding yet pick up some bloom nutrients...general hydro has a flora nova bloom for like 15 bucks, also fox farm has some bloom nutes for around 20 bucks a bottle. your running a sativa dom strain so leaves are going to be thin and wispy and the plant is going to flower slower than you average sativa/indica mix.

all in all the plant looks fine, maybe slightly nutrient deficient.

check your PH of the soil if you can and get some food into her, start off at 1/4 strenth, trim all the undergrowth because its just taking away from the rest of the plant and have some patience, your buds might not be as dense as they would if you were running a nice HID light but they will still pack a good punch...looks good man.
 
Granted it is not the worst I have seen, but all in all that does not look 'fine' to me. Plants are just going to continue to stretch as they bloom and to me they look pretty stressed out. I am generally quite optimistic and it isn't like I am just trying to be an ass here, don't attribute any tone to my posts because there is none. I am trying to be honest and actually help this person improve. They asked for suggestions and input. Mine is to be more prepared for growing: set up a better room more conducive to flowering.

Didn't see that he had t-5's...

Thought a PK booster would help as it's a good time to be using around now as white widow is around a 9 week strain no? Shiptanoic

Yellowing on the bottom isn't the start of just potassium.. Yellow lower leaves = N, P, K, and Mg def symptoms.. definitely going to require a pH check, EC, TDS, and see wtf is happening. Worry about nutes/pH before you worry about the lights. The stretch may be indicative of the genetics, moreso than the light - there's quite a few strains that have stretching-type appearances that are purely pheno-based.
 
Looks like its a bit over watered and like Nullis mentioned a possible root issue. The yellowing looks like a basic Nitrogen deficiency too me. Doubt pH is the cause as there are no real clues pointing too that.
 
I say do what you can with what you got and just save up to get the better stuff...you gotta start somewhere...its growers who feel superior because they got a little money and don't want to see the next man succeed...I would have to agree that the lack of correct lumens, air flow and so on are most likely the problem...but just throw a fan in there for now and just expect a longer flowering cycle due to you lights...next time or whenever you got it to spend invest in anywhere from a 400-600 watt hps...stay up...

T5 can grow large, dense, sexy goodness.You fellows are just a bit to hard headed.Do a sog or scrog with that light next time man.

He isn't doing a ScrOG, tho, that plant must be 3 ft tall. Granted, a scrog would have been a much more efficient use of the T5 fixture. Perhaps the light has also been further away than it should be (within a couple inches of the plants).
Not only is it under what looks like a single T5 fixture, but the walls in that grow space are barren. There could at least be some white paneling or mylar or something reflective in there. Been growing long enough and been around enough to be able to tell that this stretch has little to do with genetics and much more to do with the lack of light. Maybe there are some nutrient issues and watering issues, but over-all some of these pictures looks like plants I have seen that have been in the dark for several days.

Without sufficient lighting the plant isn't going to be able to sustain itself much less make efficient use of any nutrients you provide it. Light is the most important thing here; plants need it to photosynthesize.
 
wow. At first i had no feedback and now a lot! ha well I gotta say that its likely all good feedback so THANK YOU. From the base to the buds it is about 3 ft tall I know about the light issue which is why i started the trellis deal. Prob not soon enough. I have always had the light no more than 2 inches from the plant. The stretching has pretty much stopped and now working on the buds i guess. Yeah they look like their gonna be airy but on this grow it is what it is. When I started bloom I switched to Agromax F54T5HO Bloom Spectrum bulbs. And yeah thats the best I can do right now. I was using age old grow in my veg stage and then switched to indonesian bat guano and some mollassis when I switched 12/12. I had let the soil get a bit too dry one time and it wilted over night. I watered with the nutes and it bounced right back. So that said I never let it get too dry anymore and possibly may get more water than it should. I also prob dont have it in a a big enough pot but nothing i can do about that now. Its maybe 3 gallons. So If I removed all the old bigger fan leaves under the trellis i wont hurt the plant? Also I have never tested PH and not sure what I would do about it anyway. Again thats why im here and new to this. Thanks to all the replies and keep them coming I am grateful to gain the experience.
 
Who ever said the t5 is making the top leaves do that is totally wrong. It's obvious this plant is begging for food. I veg my girls to 3-4 feet and they never yellow like that under t5s. Quit blaming the light. This is a nutrient or a ph problem!

Here's a bit of the pH crash course:

Decent pH chart used to help work through deficiencies.. dolomite is your friend, ph up, ph down (which come in many forms) can also mean the difference between sanity, or not.
 
What are you using for soil/medium? I can't really see it that well, but it doesn't look good and has a bunch of leaves and stuff in it, not good. In my opinion, your plants look to be headed for terrible trouble with your lighting. While I'm not an all-pro, even if your soil was better, your food/water better, temps and conditions IDEAL, those lights aren't going to get the plant moving along enough to grow without stress. Your buds are made of air and pistils.

Don't sweat it too much, growing good dope takes practice and patience.
 
I'm experiencing very similar symptoms on a very similar looking strain (mine is unknown strain) at about a week into flowering. I am guessing from what you have said that your situation is similar to mine in that you used more nutes and molasses since entering flowering which has caused a pretty severe pH drop. The top leaves are most likely N toxicity and the bottom yellowing is most likely a result of a lockout due to either nutrient/salt buildup in your soil and/or a pH that is too acidic. What kind of soil are you using?
