For future reference, what might be the problem with these?

I posted a few pics earlier on what to do, and since its close to harvest there's not much to be done and the plants should be fine. At least that's what I was told.

However, for future reference, does anyone know whats wrong with my ladies and how to fix it? The problems are getting worse, and it seems I am unable to turn it around, but they are still producing so I guess I'm lucky this time. Naturally I'd rather just avoid the whole problem next time, which is the reason I'm posting this.

I don't know that anything is wrong with your plant, they are programmed to use up the nitrogen in their fan leaves in last couple weeks of life and put everything they have into trying to reproduce (sticky bud). If you feel the fade started too early, you take notes for next time you grow the strain to up the nitrogen levels more going into flowering, or even give veg nutes for a couple weeks into flowering. Allowing the nitrogen to be purged from the plant is one of the secrets to getting smoother smoke.

It is always a little sad to see your beautiful fan leaves go to shit, but it is part of the natural cycle and generally unavoidable.

Bugeye speaks the truth...
Your plants look OK...nicely done. Many first time growers never make it to harvest.

Usually when you start budding, you try to take all the Nitrogen out of the soil and plant, and bolster your plants potassium and phosphorous. Nitrogen is what makes the plants have that really deep green look. When you take that away, I could see the plants start to yellow. It is sad like what was said above, but your plants look good.

Thank you people. I guess this is good news and I can relax a bit. I did not know the part where I should start feeding potassium and phosphorus in flowering. I guess this might be the reason for the nuteburn¿ Also the different variations of symptoms, I'm willing to bet, is probably the PH which has been up to 8 in our tapwater. Sounds odd, but that's what my strips AND drop test shows so I guess that's just how it is. I had symptoms of mag def, cal def, potassium def, nitrogen def and even heat stress (temp has been at 28C during light on and down to about 22C at its coldest with the lamp about 30-50cm above the plants).

PS. forgive me, I use the metric system

No need to apologize cos u use the metric system. It makes more sense than this US Standard that we use. I kinda wish we would switch over.

See what you mean, your not getting the maximum potential weight . This yellowing and leaf drop is due to salt burn, to avoid this change soil next grow, use a professional coco mix and use hydro nutes every watering.

What exactly am I looking for when you refer to "professional coco mix"? I mentioned earlier that I don't really have access to any of your brands so I kinda need to know in detail what I'm looking for. Also I bought a full kit or organic liquid nutes for both soil and hydro. I'm guessing this should be good? The kit is for cannabis specifically, made by BioBizz.

Also out of curiosity, how can you tell that it's actually salt burn? And is this cause of the soil or my nutes?
