Bloody skunk auto (outdoor) leaf issue question

[BudBuddy]

Hey everyone,

New to the forum so thanks for your help.

Been searching and experimenting to try and fix my grow issue so decided to post as I can’t seem to fix what I think is a deficiency.

Just starting week 7 into my first outdoor auto grow (in spain and it’s legal here so thought I’d give it a go) and one of my plants is showing an issue on its leaves.

Been on bio buzz fro, bloom and top max but just on 4ml/l bloom and 1ml/l top max now. I thought it needed cal mag so added 0.5ml/l of cal mag to my water this week. Getting loads of natural light each day, temp is circa 27c consistently.

But still looking unhappy. Any advice would be greatly appreciated as I think I have about 2 weeks remaining before harvest and don’t want to fall at the last hurdle.

Hey, yes I did it looks like magnesium as it started on the lower leaves but they have been on calmag for a week and still no change.

It can’t be nitrogen as they get a good dose of that when watering, the other pictures dont really look similar.

I recon I need to start flushing them soon but was hoping to get a healthy plant before I start.

you didn't say what you are growing in that makes a huge difference in how you treat an issue , so without knowing the grow medium ,I'm going out on a limb here

1 Your pots look like 3 gallon pots if so to small expressly when half full.I bet when you harvest your going to find she was root bound
2 If your in coco did you flush before flipping , salts build up and need to be removed otherwise they get locked out and you start have strange thing showing up
# Now the good news I think your plants are fine they are just using up the N because your not giving it any with only 2 weeks to go your going to make it

I also want to say if you are in coco did you give it calmag before you planted it for some reason coco sucks all the calmag out of coco so when I'm mixing it I give it 40 mls 20 is what is recommended for plants but the 40 is for the coco

dumb question here but do those pots have drainage holes , I would invest in some cheep fabric pots the vivosun 7 gallon bags hold 5 gallons of dirt

Hey, I am growing in soil and have started to flush the plant in question, my other plants are doing really well in comparison, this is the runt of the litter at 40cm but is finishing sooner.

The pots do have drainage holes in the bottom, I think they are about 10l pots, I thunk the plant is also small due to transplant shock in veg mode, it took a week away from the growth that I couldn’t get back with it being an auto, but lesson learned on that one, (never done autos before or outdoor).

I will definitely start in final pots and go for a bigger pot on the next set. I did two to start with to learn from before I use up the rest of my seeds. I will check the root ball when I harvest to see if it has got root bound.

Thanks for your help.
