why do i keep getting the same problem???

[Guest]

Hello all I have a problem with my afghan ladies that is strikingly similar to a problem I had with my NL ladies a few months ago. First off the info :

Strain: Afghan (Aloha Seeds, www.aloha.nl )
Soil and Nutes: Foxfarm Ocean Soil, Foxfarm Grow Big (veg) Fox Tiger Bloom and Earth Juice Bloom (flower), fed every other watering starting at week 3
Pots: Started in 1 qt. round pots, trans to 1 gal. Pots, trans. to 3 gal. grow bags
Vegetative State: 28 days
Flower: 17 days (so far)
P.H.: 6.8 - 7.0
Growroom: 5ft. by 3 ft. closet
Lighting: 400w hortilux MH bulb (veg) 400w hortilux HPS bulb (flower)
air cooled by in hood 4 in. fan ducted out to room, also a small maybe 10in. fan mounted on wall.

So with that out of the way, my problem is this. As with my last grow (which was my fist ever) Im beginning to notice yellowing of the bottom leaves, along with brown patches on the yellowing leaves. Some of the middle to upper leaves have yellow/brown patches along the leaf tips and edges.

Please forgive me if I am missing something obvious, but it just seems weird to me that the same syptoms would appear again. Well any help or suggestions would be appreciated

Sorry I dont have any pics right now but Im hoping to borrow a freinds digi cam soon.

Im not no expert at this but whats you temps in your grow room? I do know that when "forced" into flowering. People usually see a lack of Nitrogen, which turns yellow as you described.

If you get a problem on one grow it is bound to come back on the next grow until you sort the problem.
So lets say your nute is missing magnesium, it is not miraculously going to have magnesium on your next grow. If you are feeding too much surely 50 years later you would still be feeding too much...
That is why grows are supposed to get better each time. You learn something new from your last grow and try to improve your next.

hello 1018
useing cal-mag would more then likely stop the yellowing....overwattering will also cause what your deacribing, make sure at let your soil dry a bit before watering/feeding ok........
peace


P.S. also bring your PH down closer to 6.5.........

Thank you for all the help everyone . Sorry it took so long for me to reply.
First off, xxosh, the temps in my grow room is between 75-80F during the day and about 65-70F at night. Also I have added a little foxfarm grow big to my water for the affected plant to hopefully fix the problem if it is indeed a nitrogen deficiency.
Blackmelo, I hear you on that, which is really why I asked the question like I did. I am hoping that it is not what Ive heard called bad room syndrom, because I have tried to apply all the things I learned from my first grow but still ran into the same problem. Thats why I was thinking it must be something else that I am just missing.
Jaws, I water about every 4-5 days at about 3/4 of a gallon each watering. I dont think thats too much because I always check to make sure that the soil around the bottom of the bag where the holes are is dry before I water again. As for cal-mag, Im pretty sure that there are both in the tiger bloom, which I add every other watering. Hopefully I can get this taken care of and figure out what the problem was so that my next grow will not be affected. Also, I have brought my PH down to about 6.3-6.7 so I hope it helps even a little.
Once again thanks alot to all 3 of you, and any other suggestions or advice would be appreciated


peace

Sounds very simliar to my nutes, lights, soil.
When did you start having problems with the leaves?
Are the brown patches crispy?
For my first couple grows with ocean forrest, I overferted because I started feeding before the plants had used up the goodness in rich soil.
When was your last transplant and how soon after the transplant did you fert?
I agree with jaws and blackmelo as well, a shot of microblast or cal-mag might help rectify what is happening but first figure out if you are overferting.
If that pile of nugs is from your first grow, I think you don't have much to worry about

 

[Sleepy]

keep your pH in that range...(6.3-6.7)...

water them less frequently...when the pots feel light.

give 'em a nice flush with just pH adjusted water, see how they respond (give them a week).

 

[Guvnor]

^^^ Sound advice from sleepy

Be careful, even if you plants dont show signs of overferting, a build-up could be taking place in the soil, causing a number of things to go out of whack. Test the run off after you run some water through the plants, to see if things are flucuating below ground.

All The Best

Thanks BigJilm, I think you may be right. I transplanted about 2 weeks ago from 1 gallon plastic containers to 3 gallon grow bags, but just to point out, the leaf discloration started while still in the 1 gal. After transplant it was abouit 10 days before I fed tham again. The brown patches are indeed crispy and almost every leaf, even somewhat healthy looking ones have crispy brown tips on em. Im gonna try sleepy's advice and lay off the nutes for a few weeks.
Guvnor, Thanks for the help. I think that might be precisely the problem Im facing. the foxfarm soil is very rich to begin with and I neglected to take that into account when figuring my feeding schedual.
Well Im gonna give them a while with just distilled water and see how it goes. Thanks for all the help everyone.


Oh yeah, and yes those nugs are from the first grow. It had even more problems than this time so Im not too worried, I just want to learn as much as possible for the next time(s)

edit: Sleepy, I just wanted to say how much I love your pics and growing style keep it green

If you are vegging for 28 days then I would guess its the container is too small to support a healthy root system. I have a feeling your leaving them in the 1 gallon too long and it is getting root bound a little bit.
I get this problem all the time when I leave them in there 1 gallon containers too long.
I usually start in a plastic party cup-then to 1 gallon- then into 5 gallon right before flower. if you look in this my gallery you see that I do as well have a few crispy leaves on the lower part of the plant but after transplant and by staying on my regular regimen of nutes it pulled out fast in the 5 gallon.
Its just another thought to toss in.....good luck on your grow man!

 

[Guest]

Thanks ehonda, for the great advice. Im thinking that it could be a mixture of all three of the things that have been mentioned. I did in fact leave them in the 1 gal. a few days too long (at least thats what I think) which wopuld explain the yellowing/crispyness. Thanks everyone for the advice and well wishes


keep it green,

like sleepy and his big sig says.. get that ph down a little. min 5.8-6.5 max. Look up 'PH chart'. I think it says that if you're ph is too high you can get N burn when you shouldn't be.. PH affects how nutes are absorbed.

 

[Blackmelo]

guerilla, as you can see all of us are just taking random guesses here.
I did not specifiy a specific problem because there is no real way of determining it by desciption.
Can you not get a picture, even if it is not very good, it would help us narrow down the problem.
PH range for soil is 6.4-6.9
PH range for hydro, coco, and other soilless mediums is 5.4-6.4

 

[LEGI0N]

^ "you see no one knows.. but me.." lol you're a riot.

 

[Guest]

Thanks legion and blackmelo (again) I am sorry that I dont have a pic handy but I will try to post some asap. The best description I can give you is that the lower leaves are yellowing evenly until the whole leaf is yellow with small brown crispy spots on the edges. Also almost all the leaves have brownish tips to them that are also somewhat crispy feeling, though not as much as the lower leaves. I tried to give as much info as possible but whatever else you think you need to give me some sound advice, just ask and I'll find out. I really do appreciate all the help from everyone so Thanks again


Here is a blurry pic of my last grow that shows the brown tips that Im speaking of, hope it helps until I can borrow my brothers digicam. Thanks

 

[LEGI0N]

Yeah man, just by looking at your pic and your nutes.. It has to be some thing PH.. Unless you've totally messed up your mix rates it shouldn't be nute burn.. I mean EJ it very light and BB is even less.. and it's only your PH that stands out at being an issue.

The bad thing is that it's not going to grow back.. I mean what's yellow will stay yellow..
