Is this a calcium deficiancy it is only on one of the plants noticed it today I am pretty sure I would of noticed before if it was there.
It's on quite a few leaves now.
Browning of leaves has developed quick and is spreading fast

I think I have been watering to long at 5.5, and I have picked up either a calcium or magnesium defficancy. I am unsure of which one it is. Will upping the PH to 5.6-5.7 fix my problems and maybe add some calmag in to the next feed?
Just came across this
Plants grown in coco coir need a pH level ranging from 5.5 to 6.3, depending on the life stage of the plants. Normally, pH is adjusted to 5.5 - 5.8 during growth and 6.0 - 6.3 during bloom, which helps the plant to assimilate the most demanded nutrients at each stage.
is there truth to that?

Check out the coco section mate. I forget where the chart for nutrient uptake is but it basically showed you start at 5.8, nudge towards 5.9 mid veg then nudge again to 6.0 during flower.
It may be oversimplified here but I've a few diaries saved that I go back to often to study.
Look up: New Growers Guide to Canna and Coco. Even with different nutrients, it's a great resource.
Don't forget, I'm not knowledgeable. Just scoured this forum thoroughly.
Cheers,

I always aim for 5.8-6PH when feeding in coco,I add 1 tbp of epsom salts per gallon of water,I've found that LED panels can cause the same issue if they are too close to the plants as well.

Thanks guys i'll check that out
The smart growers here thought me to use ebsom salt or a cal/mag as a folar spray once a week from veg and 1-2 weeks into flower. Ofc fixing your PH is more important but its a good habit to haveOriginally Posted by SmallTimer
