Does anyone know what the reason for this could be?

im on house and garden nutrient line, with a few teaspoons of cal mag, also add 8 teaspoons of epsom salts
Also just started using rock resinator addative just before this issue started.
Week5 of flower
Ph 5.8 water temp 19c
Feed 1300ppm
Humidity in day 55/ 60%
humidity at night 50%
Co2 1800ppm


nitrogen def
could it be cal/magnesium def
Cal/mag toxicity
light stress
Sulper def
Pk toxicity or def

u got some nice buds growing there.. if anything problematic with that RR them bigger leaves would give u a sign.. apparently they're liking it for now.. https://herbiesheadshop.com/blog/cannabis-stem-splitting-all-of-your-questions-answered id give this a read for a more economic way to get them powdery buds if its what you're wishing for ;)

The plants look good, maybe a bit of tip burn on the leaves but not bad at all. I if we’re to do anything it would be to back off or quit the Epsom salts. House and garden lists they have a lot of magnesium already, and you added calmag on top so probably no need for more.

You can lock out K with too much Mg which will look like burned tips and edges with yellowing near burn

Thanks how much epsom salts would you add per feed? Maybe I need to cut back on the epsom salts.

i think it might have been the new product rock resinator I started using but I will see in a few days if it was as I cut it from the schedule.

A few teaspoons of CalMag, and 8 teaspoons of Epsom Salts.... Per gallon? Per?

2.6 EC is too high. You'd do well to cut back on everything you use. What other additives are you giving this plant?

Per 350L

the same additives as on the other post,

but I just realised i am on currently 2 days into week 8 of bloom and still havent used a pk boost I think Ive messed up badly
If you dont use pk boosters do the buds just not swell and ripen at a small size? Or do they just take longer to ripen? So a 60 day strain could end up as a 100 days to finally ripen for example?

They are like 60/70 day strains as well.

i was feeding 1000ppm before but the guy at the grow shop said to up it to 1500ppm but decided to be cautious and go with 1300ppm
