3-4 weeks in to flowering my fan leaves are starting to yellow very fast

An update for anyone who is curious or is having the same problem and looking for a solution. I have her stabilized and shes not showing any more signs of yellowing. There were two things I did but I believe that only one of them had an impact. The first thing I did was transplant in to a bigger pot. I wish I had my other ladys in bigger pots now to and my next grow that is on my list todo. The second thing and what I think made the biggest impact was I upped my does of nutes to about 1 1/4 strength. This seemed to stop the yellowing and I dont see any nute burn. I am using the GH flora series with some cal mag and floralicious. Hope this helps anyone who is having the same problems.

interesting that you exceeded feeding them a full dose and didn't see any burn. How much were you feeding them before? Also, are you adding cal mag to tap water or RO water?
I never went over a half dose which may have been my problem.

use some veg nutes to up the nitrogen, looks about as simple as that really. Just make sure to realize when there thirsty because of there upped intake of water in flower.

I was feeding them off the feeding chart for GH for growing in soil. I am adding cal mag to tap water that I leave sit out for a few days before I use it. By the sounds of how little nutes you were giving your girls that was your problem. Next time try upping the dose of nutes before you start to see yellowing of the leaves. Another thing I have noticed among the people who are having the same problem as us is that we are all pretty much using 3 gal. pots. This may be contributing to the problem but transplanting during flowering will cause problems of its own.

Yeah, I'm glad you figured out your problem...Hopefully that's mine as well. Maybe I'll also add cal mag. I was thought you didn't need to add cal mag to tap water but perhaps that's not the case. As far as the pot size I've had pretty good results in 3 gal pots but who knows.

I am just keeping this thread updated, heres a pic of the lady that was having the problem, The picture actually makes it look more yellow than It really is due to me having to use my flash. Shes actually looking quite healthy and the buds look just as big on her as they do on the other completely healthy plants. I am just at the 5 week mark in to flowering and am just starting to see that last bud swell. I also added molasses in to my nute line up today for the first time. I know it may be a little late to start using it but I figure it can't do much harm. Here is a Picture of her sister that was green the entire way through flowering. and here is a pic of how the buds are doing, looking frosty for some bag seed.

And lastly heres my veg room and my "heavyweight fruitpunch" in the front and Nirvana ak48 in the back.

damn, that plant ended up looking great! Was curious to how often you feed while using ocean forest?

Yeah actually surprised me how well shes doing! If you look at healthy one and the one I had the problem with side by side its clear that the healthy one has a lot more leaves on it but as I said the buds are about the same size. I think she lost just under half of her leaves so I am kind of expecting it may effect the over all yield in the end.
I am feeding them every other watering and I water every 2-3 days depending on if they need it or not. The ladys in my veg room are in coco though, the growth rate and how healthy they look in incredible. I really don't think I will be using soil ever again. Hope this helps PlantProblems and you get your ladys healthy with fat dank nugs!

Haha, thanks. I keep wanting to ditch the ocean forest but for some unknown reason I keep going back to it to give it "one last shot" Maybe I'll try coco or a soiless mix for the next go around. Also, you add cal mag to your tap water? Do you add a full dose?

Also, what kind of system are you using to feed your veg plants?...they look amazing

I am ditching the OF and never looking back to soil period. Trust me once you make the switch you will be very happy with the results. Also it simplified a lot of things for me. I dont have to mix soil up, I just use 100% coco. I clone straight in to coco with better results than any other medium/rockwool/rootriot cubes. Also I put them on a drip system so no more hand watering. My plants love it therefor I love it.
I do add calmag to my tap water at 5ml per gallon. I am not sure what a "full dose" is.
I am really starting to wonder if my ppm of my tap water is high enough for it to negatively effect my plants. I was thinking of buying some RO water from the store and use it for the last part of flowering through my flush. Being that I just added molasses to my nutes I know I have quite a lot of stuff in there. I really need to just buy a meter so I can not have to sit here and wonder. Matter of fact I am going to do that right now. Anyone have any input on a meter. Does it have to include both EC and PPM ?

My veg room is 4' 8 bulb Hydrofarm t5s and a res with a drip system. Its really simple actually.

Yeah, I think I'll make the switch to an ebb n flow or coco next grow. How often do you change your res? Any good tutorials/links on how to build a drip system?

Also, have you had success with ocean forest in the past?

I fill up my res every other day or so the nutes stay fresher and I will take it out every like 2 weeks or if I see its dirty and clean it with bleach and water. For my drip system I just have my plants in pots of coco with a make shift drip ring in each one. What I did was order this
http://www.dripirrigation.com/drip_irrigation_parts/432
and It pretty much comes with every thing but a pump and a few connector pieces. if you do order it make sure you order extra 25 1/4" Barbed Connector, Long and also like 50 or so DIG 1/4" Barbed Tee then what i did is hook up the pump in the res run the hose out through a hole I punched in the top of the res. Ran it the length of my room and then back again to the front. Set where I wanted my plants in relation to the holes I was going to punch in the main line. Then I ran each indivudal line to the pot and add a Tee joint then more tubing then another tee joint, more tubing and then one more final tee joint. So its a line I can wrap around the base of the plant with 3 sepriate places for water to come out of each line. Does that make any sense? I will take a picture it will probably make alot more sense.

These ladys will be a month old in 3 days from being a seed in the ground. They look awesome I will never go back to soil. Another of the biggest things i noticed with coco is the ROOTS hold crap there are so many roots. That and I have been using the "Rootastic" on them. Lovey combo

Something about that Irrigation kit though, I didnt use alot of what came with it so you could probably get away with getting the parts individually for cheaper.

Ocean forest Ive never used but this one time I used to go with the Humboldt mix

Thanks so much for the info! Those plants look truly amazing for being a month old...those thick stalks..wow. What model pump do you use? You mentioned previously that feed every other day? So you use plain water on day 2...feed on day 4....water day 6 on and so on? Cleaning the res between feedings? Is it on a timer or do you plug it in and turn it off once you see runoff at the bottom of the pots?

http://www.hydroponics.net/i/131589
That is the pump I got. It works fine and all the lines give out water evenly. I actually feed every day with nutes all the time. I just fill up my res every other day. I clean it every week or two. I have it set up right now where I just plug it in and i will stand there at time it, takes just about a min at this stage but I have it down to where my run off is veryy minimal. My space is kinda limited in my veg room so i dont have any drip pans. I haven't found something that will work yet.

interesting...In hydro I've heard people on timers watering their plants for five minutes five times a day (or something like that) So your method is one thorough soaking a day? In soil as you know, people don't water again until the pots have dried out...I suppose coco is a different type of concept?
