Been flowering for 14 days. Left light on for 48 hours on accident. The leaf issues started after a week of flowering, but the top leafs got worse of course after my accident. I increased phosphorus feeding in case that was the issue. I did two feedings this week (florabloom 10ml removed link )

looks a bit like light burn but that is not cause by being over the time just by being to near to the lamp ....

so I would say its more looking a def maybe Cal/Mag ....

but its only guess could be a lockout as well.

Ph is off mate, for coco it needs to be around 5.8, bring the pH to the right level and she will be much happier. Its just with the ph being so high, the plant isnt able to get food that is in the medium. So correct that and i think youre good to go Smile

@macky i know this is going to sound crazy but i have more problems in coco under 6ph lol if i hover around the 6-6.3 mark she is golden lol. every bit of info i can find on coco says that it should be around the 5.8 but i always have issues at that ph lol i am in Oz so i mean we are backwards and do everything the hard way but still super odd lol

yeap @macky is right mate.

I had the same thing early last year in a Coco grow. pH was too high. I dropped the pH (and rasied the temps to 25°c on and 20°c off) . The plants picked up within a five days and and new growth was good and healthy. 

Best of luck mate, hope it works out👌

2 things slightly confused by...

First is Medium you say is Soil, coco....2nd your lights on/lights off is within 1°

Is this right, as Ph is different in the two mediums, not good to mix

Thanks so much for taking the time to address the situation, it is much appreciated.

my inexperience is already showing with the soil/coco misunderstanding. This is my first grow. I used 1/4 coco, 1/2 vermiculite, and then fox farm with worm castings mixed together. 

I did realize recently my tap water ph is around 8, when I mix nutrients it goes to 6.6-6.7. My runoff has been around that too. So I order ph down. If my soil is a mixture would lower ph still help? Did I mess up the soil from the start?

 

i added some cal mag to the soil today.

 

thanks again

Also my temp doesn't change much. I used to keep it heated at 22-24 but stopped the heat when I switched to bloom

@mikeyisleany yeah ph down will help, as Macky said shoot for the 5.8 mark, it will probably take a few feeds to bring the runoff down but you will be making the nutrients more available to the plant at the lower ph. be careful with that ph down though, one drop into the bucket at a time, and always add ph down after you have added and mixed your nutrients to the water. And yeah get some pk into them they will love it !

You have come this far mates o it couldnt have been that bad, but its best to pic one or the other Smile

Are you adding any extra PK to the feed? She will be needing some at this stage
