    Default Heading into my second grow and some help is needed

    Hi guys , I messed up big time in so many ways on my first grow, I messed up at the end too , the plants were very small in height but absolutely packed with buds, there was 0 air movement in there coz it was so bushy and I had to throw about 150 g in the pin , lots of MOLD...


    Okay again using same growtent 120x120x200

    Lights : LED sunpled g2
    Diode: samsung lm301b
    Power:800w
    PPF : 2320 umols

    Have the ac filter , fan inside ... lights are 120cm wide as tent from one side to another , full coverage

    Using this time 3 critical orange punch autos.
    30lts fabric pots .
    Growing again in coco mixed with perlite


    My main question is the height of the lights , one guy with same lights told me he goes 100% of power from start to finish , in that case do I need to add more co2 ? Last time I messed up by adjusting the power all the time

    Sometimes question can slip through the net, you could have given it a bump..we're all members/growers just like yourself..

    It's a shame you feel that way Quotientcatalysed....cheerio

    I can't tell you anything about Auto's or Coco, just don't know how those work. But I am just going out on A limb here and guessing you burnt your plants with high PAR. 2320 @ 800Watts, would be that at 12". Just my guess. I would think you would need your lights at least 24" during flowering. If you had them much closer than that, you might have burnt your plants/Buds. Might not have been mold. This is all A guess, because you haven't really give us much information to go on, so can only assume. If you have A PAR meter, you need to keep it center at 900 to 950 and no more than 1,000 at any time during the grow.

    The height recommendations in your screenshot are what I use when I'm growing with my LEDs and they're very powerful. So I bet they're about right. I wouldn't bother with CO2, I've grown some monster plants and had some great yields and never used it especially with coco. The thing to remember with autoflowers is they grow the biggest and the best if they're a little bit hungry, especially the N.

    When you are working with Coco, you want to mix your nutrients the most alkaline first and then the least alkaline last. You want to get 10 to 15% runoff every time you water and you want your pH to vary between 5.8 and 6.2 or even 6.3. When I'm mixing up my nutrients if I get them all mixed and at pH is 6.3 I'm happy, same thing as if the pH is 5.8 I'm happy anything in between I'm happy. I do want my pH to vary once in awhile though, so if I'm hitting 6.3 every single time I'm going to lower it a few times. You will need to feed with every watering, anytime you believe you have nutrient deficiencies with a good quality canna nutrient you need to suspect your lights are too low. LED lights will show all kinds of strange deficiencies when they're too close to the plant. They will also usually cause an increase in calcium/magnesium use. you need to be careful and source your calcium and magnesium from the lowest nitrogen source you can find. Or you're going to have to use a nutrient line that'll allow you to reduce your nitrogen by about as much as you add high nitrogen calcium magnesium.

    Sounds like you already know that you need more air flow and thinning of your plants. You have to be careful thinning your plants out, it can make them grow a lot faster or it can really hurt a stressed plant. I use defoliation to get bigger yields and bigger plants or sometimes just to slow a plant down a bit. However, it took me a couple years to really learn the defoliation correctly so I wouldn't go for it too much right at the beginning. I would simply clear out some of the leaves that give you trouble with air flow and some of the inner stems little spindly ones reaching out for the light and leave it at that.
