    Leaves are showing multiple problems

    This plant was OK yesterday. Today, leaves are yellow, she is sagging. PH is 6 as it is from day one. I underdosed with organic amendments. Should I transplant? It's flowering and buds are still pretty. Click image for larger version

    It could be that because of pot size your plant can only support so much above ground. Buds get priority, so lower leaves usually get shorted. I've never grown in regular soil so you ought to wait for somebody more familiar to respond.

      That's what I was thinking, but then again I have same plant in other pot doing just fine ( for now at least).

    She looks thirsty AF. Are the amendments your giving her dry or liquid? If dry you won't see much of a response for a while. They take time to break down.

      I'm giving her liquid amendments from the start, it's organic program and it was fine, it's fine with all other plants. I've been watering her every 4 days since flowering. I measure the soil before I water. It's that some leaves are falling off...the oldest ones, the rest started clawing and having curled burned tip as in nutrient burn.

    Welcome

    It will help if you could tell us a little more about your set up and environment(temps,RH,soil ,watering schdule,nutrients,lighting...etc) pretty sure someone could help you out

    In my opinion 6 is a bit low for soil grow. I aim for 6.3 to 6.8. I alternate between the two. Different nutrients need different ph to be used by the plant.

      Based on the limited info you've provided, my first inclination is that they have had heat stress. I've also seen similar effects from an over feeding of nitrogen during flower.

      Are you using nutirents designed for bloom= less nitrogen and more phosphorus and potassium in flowering. Veg plants need more nitrogen less phosphorus and potassium for more growth. Imo your nutes are way to hot for flowering, burning your plants up. Also how close do you have your lights to the canopy?

        Yeah, I use bloom nutrients. Lights and temperature are perfect. I'm thinking that there is too much colas on this plant (13) and the pot has become too small.

      5 C is COLD, they will do better if not under 20 C, 6.0 PH may also be low as said.
      How do you water, how often how much and why?

        Please decode this line for me
        Low temp 20,5-21,5 Celsius
        to me it says the temp is going down to 5C and up to 21C, am I misreading it?

        Yeah, you are missiterpeting it.. Temp is from 20,5°c low, to 27°c high

        Most Americans don't realize that decimal points are commas and not periods in other parts of the world. So that's a range of 20.5 to 21.5 degrees Celsius.

      Ph, nutes, or temperature can't be the problem. The only thing that comes to my mind is too many colas for that pot size. 13 colas. I'm gonna transplant to 25l bag. And see what happens.

        There are threads here on growing in solo cups all the way to finish, that's right 8 OZ of whatever in the cup, the small amount of media has nothing to do with it, care does.

              Have you looked for bugs in the soil?

                Just a look. I didn't dig deeper, but I have bug traps set, they worked perfectly in the past

                And wouldn't I have a bug problem on all plants since they are easily spread with ventilators?

                Could be they have just infested one plant so far and have not gotten foothold on other plants yet. Might not be bugs but worth a look.

              Calcium can’t get absorbed under 6,2 for a soil grow.
              so the Ph is too low.
              what kind of soil is that? You just mention soil not what kind ? 20% perlite is a little on the lower side in my opinion. What is the pot size? And how much water are you giving it. ? And how often ?
              Just because people are over 50 doesn’t mean they know everything.

                The soil is Composana potting soil. And it's perfect. My friend had about 15 runs with that soil and his buds looked and tasted like a dream. It wasn't Ph. PH is fine, I have a very hard water here and everything over 6 was killing my plants. They are thriving with Ph6.

                Just because someone else uses it, doesn’t mean it’s a super soil or something. It’s just a scientific fact that calcium can’t get absorbed by the roots. And the soil look at way to “heavy” not much perlite in it.

              Even though you seems certain that it isn't a nutrient toxicity problem, it might be better to error on the side of caution and give it a good flush or even two. It's unlikely to do any damage and could possibly save it. You say the plant turned very rapidly and that is often an indicator of over feeding. Deficiencies tend to develop over time.
