Leaves yellowing too early

[hairyman]

I have had a problem with all my grows so far(10) that I cannot correct. I see pictures of plants with buds near harvest where all the leaves are green. Mine are always yellow. When the plant is ready for bloom I switch to bloom nutrients (fox farm tiger bloom) usually 10 ml to 4l of water and 5 ml of FoxFarm Gro Big which I use during the veg stage- every other watering. Everything is nice and green until bloom starts then the loss of color progresses too fast in my opinion. If I add too much Grow Big during flower along with the Tiger Bloom I get nutrient burn. What do others do at this point in the grow to maintain color? I know that less nitrogen is needed during bloom but I am supplying some. The weed I get I am happy with but the plants look bad by harvest time. Any ideas? Thanks for any help.

How old are your plants when they start to yellow and do you ph. your water?

Also, I hope you realize that your plants should look fall like before harvest in my opinion. Are you growing the same strain each time you grow, just curious? I know Nebula has some reads out there using the FF trio that might give you some insight on better nute management. I don't have any experience using the FF nutrients but there are people on this forum that do

Don't know Hairyman. I had the same problem, and I started to give my plants nitrogen along with blooming nutrients. In the last few grows, I didn't have the same quick yellowing of the leaves till the end and near harvest. I use Biobizz products. I also started re-potting into my biggest pot size just before going 12/12. The extra nutrients in the soil seem to help.

I have been giving some nitrogen along with the bloom nutrients too. I will have to experiment with the amount I guess. Thanks for the help.

I do ph my water which is a 50/50 mix of RO and filtered. They are in bloom but the yellowing seems to start too early and proceed too fast. I do get a good amount of bud though. They are usually nice and green before flowering so it is not nutrient lockout. I grow a variety of strains. I know that they are supposed to yellow to some degree but mine are always totally yellow by harvest. Thanks for the help.

I don't use FF nutrients but I do have the same issues with yellowing/spotted leaves. I've noticed that it's a little different rate of progression for each cultivar and more so for photo plants than autos. It usually starts at the bottom and works its way up. My weed is a little raggedy looking at harvest, maybe not the prettiest, but it will get ya high.
