I never get replies on this forum

it's the weekend.......the sun leaves are naturally going to turn light green then brown but the other leaves should stay green for awhile if you are not feeding bloom you will get nute decencies because the plants need extra cal mag. Autos are so fast that by the time you see a problem it's too late to do much about it and the moisture would be better on the dryer side.

My auto is not fast because I repoted into 4 gal pot.

She's week 11 atm and 4 weeks into flowering...
So feed her more nuts fixes the problem?

You do know you're not supposed to repot autos right? And 3-4 litres is a lot of water man

Hi, I was told to water 20% of the total soil container 15L: 100 x 20 is 3 liters.

I had to repot due to rootbound problem, the plant would have died.... I fixed the problem by repotting which is why im in week 11

by fast i mean start to finish, veg. pre-flower and flower, you feed grow then change to pre then to flower then a flush do the math not much time.

With leaves that remain largely green but going yellow, then brown at the tips usually indicate over fertilizing. If you are giving fert with every watering, this needs to stop. Not only is it over-ferting, but at this point in the life cycle the plant is finishing, meaning that this is only an annual plant, lives at the most for one year, and dies naturally at the end of the cycle. Since you've been flowering for close to four weeks, it's apparent that the plant is just about done. You have good bud formation, or so it appears, which is another indication the plant is close to the end of its life cycle. Give nothing but water and if you want, you can harvest about one week or so from now, or just let the plant die naturally and harvest then. Most growers can't wait that long but it does give time for the plant to use up whatever nutrients are available and this tend to make for a better tasting product, or so some people think. About the watering, I wouldn't follow a formula like give so much water per unit of soil. Instead just water when the soil has dry out some. When you can pick up the container and it feel pretty light, then it's time to water. Drying the soil out allows oxygen to get to the root zone which promotes nute uptake. Keeping soil wet pushes air out and isn't the best thing for a grow. Also, I suspect you're using too much nutes as well, so I'd go a little easier next time and see how the grow goes. It's easier to adds nutes later than to remove them.

You were totally right its because its getting close to the end... I didn't overnute though... I think I overflushed it.
