    Young plants with poss cal def appearance



    Greetings from Ireland folks

    I have 6 6 week old Special Queen plants. First 4 weeks the were happy in BioBizz Light Mix soil with defluorinated tap water only (220 ppm). They were repotted to 50% Light Mix 25% vermiculite 25% perlite. I know that mix is half way to hydro, but I got burned last grow with 'super soil' so I took slownickel's advice on having a speed boat soil rather than titanic. They were happy with their move and I was easy on the nutes, NPK 25:15:15 300 ppm. Another week passed with good growth, then the first big cut for manifold training. I was expecting them to be stressed to a standstill, which they were for 3 days, then took off. Four or five days brown spots appeared on one leaf of one plant. I think it's calcium def, they're are appearing on all plants. I've tried a 50:50 tap RO mix and added some CalMag making it 300 ppm, applied as a foliar spray, no good. I then tried NPK 25:15:15 150 ppm + CalMag 150 ppm to get it in thru the roots, no improvement. Both were ph 6.8. It's an indoor grow with the supply air coming thru a pollen filter so I don't it's disease or insect. Tbh I'm guessing on the foliar spray. I've read it's a fast to fix a cal def problem, but in terms of how strong the mix and how often and when I couldn't find anything definitive.

    The pics are taken under full spectrum Migro LED lights. Seen thru a grow light filter the overall colour of the leaves are not as yellow and off green, other than the spots they look pretty good.

    Looking forward to your wisdom.

          test runoff ec. if its too high you probably have nutrient imbalance/salt accumulations
          coco need big runoff to be sure to rinse all acumulations each day

            What's wrong with these?

              Looks to me like the potting mix has had a little too much nutrient ... or you've put too much fertiliser on.


              I 'm assuming those pots drain well?


              Looks to me like you need to transplant them into bigger pots.


              Soil pH test kits are cheap at the hardware.

              If you know yr pH is right that is a good starting point for accurate analysis.

                & don't forget to turn off the house fan while you're out watering the plants !

                i left the fan on, pumped lots of hot air into the house, early in the morning.

                A/C never caught up.


                oh well, got something to focus on today -
                give the plants their daily ration of water so they can do what they do best.

                covering the black plastic with aluminum foil & cloth, seemed to take care of my own Sick Plant problems.

                      This is hard to fix. You need Iron Sulphate. Buy some of that and follow instructions on the container. Maybe HALF strength of what they say on the label. You can always do it twice if once fails.

                        Last year too? Then the problem may be environmental.


                        I doubt the problem is overfeeding because the plants aren't dark green, no tip scorch, etc.


                        Just a hunch ... have you got termites in yr garden? In any case pull one of those plants and look at the roots. You may see chewed roots.

                        It may also be Nematodes which can be fixed by watering thru Molasses at One table spoon per gallon (4.5 litres). Nematode affected roots have lumps on them.
                        Possible chemical spray drift. Roundup sprayed next door on an unfriendly breeze will do this.

                          Crinkly leaves

                          Hi,
                          What could this be?
                          One of my plants has deformed leaves. It looks as if they are drying up. The leaves have been deformed ever since it was a seedling. The plant has been treated the same as the rest of the siblings, which leads me to the conclusion that it’s not the environment. Is it a disease or just funky genes?

                            I would be inclined to think there is an oddity within the soil of that particular pot. Some mineral excess/imbalance.
                            When you finish with the plant have a look at its roots for symptoms of disease.
                            But there's not much that can be done at this stage. I think.
                            Enjoy yr other plants!

                              I have had several sativa varieties that do that when small, clones or seedlings. It always happened when kelp was present, newly made dirt or soluble kelp applied at transplant.
                              They have always grown through it in a few weeks.
                              Proud to be an indoor sativa masochist.

                              Still adrift in Hilbert space.
