So I'm theoretically about 3 weeks away from this plant being finished. The yellowing problem start a couple weeks back, but being my first plant ever I'm not sure I ever got a handle on the problem.

So here I am, watering every other day. Feed, water, feed, water...

Using 10 - 30 - 20 fertilizer... which I acquired about 2 weeks ago as an attempt at fixing this issue. I started from beginning with DNF nutrients.

Now I'm not looking for a miracle, I just wanna know what I'm missing for next time.

Now there's the odd reddish/brownish tinge as can been seen in the one pic.

Thoughts?

the eaves will naturally starts to yellow towards the end of the growing cycle, which is natural since it is reading the end of it's life. i could not see muck for spots so it does not look look like nute burn to me.

Did the plants leaves start to yellow at the bottom and work its way up, if so I am guess just natural for the life of the plant.

Ya thats pretty much how it happened... started at the bottom, worked its way up.

If anything I feel I may have been a little too conservative with the nutrients...

Thanks for the opinion.

well dont over do the nutes... they build up in the medium and become available with other waterings that dont contain nutes... its not going to get green again, but it most likely wont get worse.. in the final week or 2 ur going to want to flush the hell out of it anyway,

definitely looks like old leaves dying, nothing to be worried about, just chop those leaves away and put them in the compost heap

A good nutrient formula needs to stimulate all aspects of the plant's growth and health-roots stems and leaves to start-the structural period of growth. And this means high nitrogen, appropriate phosphate, pretty high potassium, appropriate magnesium, calcium and sulfate-and then, of course, the full spectrum of micro nutrients. The plants go through their life cycle and they are triggered to change to their reproductive mode, typically by a change in day length-this is called photoperiodism.
An indoor gardener classically alters the light schedule from 18 (or 24, in a lot of yer wasteful types of grows around here!),hrs to 12 hrs of light per day. W/in a week or so the plant should strart to exress flowering. As we see the first sign of flowering, we CHANGE THE NUTRIENT BLEND into something very different so that the plant is able to produce flowers. As the plants continue to grow, we can further modify the nutrient blend, making it SOMEWHAT THREATENING TO THE PLANTS!!! The plants respond by CONVERTING ALL OF THEIR GROWING ENERGY TOWARDS MAKING FLOWERS to prepare for the next generation. You could say that plants are all about sex and all about their children The essence of life is defined by a limited lifetime and preparations for the next generation.
When plants are growing in a perfectly happy life, when they are young and in vegetative mode, they have no particular reason to reproduce. They're secure and growing vigorously and becoming bigger and stronger. But, when the trigger comes of daylight shortening, the plants are being told by nature that winter is coming and the end of their lives are @ hand! And so, @ this point, the plants have to completely change their priorities towards reproductive growth. By switching the nutrients to something that enhances flower growth-and REDUCING NITROGEN SIGNIFICANTLY-the plants are now threatened by the nutrient regiment. They ARE NOT ON A STARVATION DIET, BUT A MODIFIED DIET that stimulates and enables reproductive growth! There's a different set of proirities going on from the grower's point of view, and the plant is responding. So now the job of the nutrient is to help the plant produce these wonderful flowers So, we're really now about helping the crop to flower-tremendously, because flowers are the precursors to fruit (BUD!!!!), and seed (or forcing her to try to pollinate by not intoducing a male). We provide the elements needed for abundant flowering and we reduce the nitrogen that was needed for early structural growth while ENHANCING INGREDIENTS NEEDED FOR FLOWERING. Remember, you can not compel a plant to enter the reproductive phase through nutrients alone. Nutrients are enabler's-not trigger's. Day length change is a trigger. It's telling the plant that winter is approaching as days get shorter. But when you apply a trigger, you also must apply an enabler so that the plant is able to make that transition. If we were growing in a deficient environment the plant would not be able to reproduce very well so we provide what is needed for flower production and reduce the nitrogen that is needed for vegetative growth!
