I need your Help !!

The supermix contains Seaweed , Volcanic Rockdust , Batguano, Wormcast, Wheat bran . And when I see that they gonna fade , this happens mostly at week 7-8 I give them some Batguano this works always good and saved most of my plants .

So it’s my own soilmix with 50/50 Coco and Earth from Biobizz , I make always a supermix that works good for me , the other 4 lady’s showing signs of a little N Tox but it’s not that bad they gonna use that till harvest . I only giving water without pH measure my tap water is about 7.8 to 8 with a ppm of 280-290 . Till now I haven’t giving them any nutes cause like I said it’s a super mix that last mostly till harvest 75% just - Humid Acid , Mammoth P , and now I started 1 week before to give them some Bud Candy from Advanced Nutrients . And for the first 2 weeks Canna Bio Rizotonic . Also the Bat Guano because they faded a bit to early this time , After that I gave them 4 days ago Green Sensation but only 1 ml on 2 L water . After the Green Sensation It started to get worse on them 2 , the Gelato is still healthy but starting to get the spots too . It’s only the Blue Dream that looks so bad , and it starts from top to bottom , the bottom leafes still healthy green . BTW These are Autoflowers Thank you for answers guys

Just read below. Green pal you say. I reckon it's a bad mix of different nutrient brand weather it be your soil mix not working with it or whatever. And btw your PPM you are giving is compounded on top of whatever your current soil EC is at. What was your baseline? Like if you had nutrient lock then added a 600+ mix Maybe on top of a rich soil mix. Idk, it's defo a nutrient not gelling or working well together. Is there anything that you are giving or mixing nutrient brands like a cal mag or something?

Can't c the diary and what nutrients u are adding. The EC isn't too high for that stage. I had something similar happen when I mixed GEH trio with a dif nutrient brand and had very similar looking issues. Have your leafs dried up like it's a N tox but it's not a N tox. It could be a bad gelling of nutrients. As I had the very same thing happen to me on a 480ppm mix but was in DWC but I'm sure it would of happened with the mix had it been added to soil.

PS. Your PH level looks alright. I like myself having 6.3-6.5 in flowering stage.

Hey SirSmoke, 660PPM( 1.32EC) is really low in flowering stage, it should at least be 1.8. It totally depends on how big your plant and buds are and how well the leaves look. In my grows whenever it is inside or outside, i start the flowering stage with like 1.6-1.8 and end it with 2.3-2.4 EC I even know people that go higher then 2.4 EC. You should give them some more nutrients, your plants show some diffencies as well.

I started to give them 4 days ago Green Sensation from Plagron the first time and it’s getting worse , can this be a Calcium lockout from to much potassium ? It’s just the 2 lady’s , the gelato looking much better but it’s started too on her now . I back up the light 20 cm higher , runnin a 300 LED Lumatek Attis . They are on day 56 now . 2 weeks ago I gave them some Bat Guano cause they started to fade a bit
