Hey there ;that definitely looks like k deficiency. Also would say that your nutrients and environment conditions are on point ; would recommend to let the pot dry out completely before you feed again if you are not already doing so. Also would suggest to check your calcium availibity in every one of your nutes and not just canna calmg. Excess of calcium can look like k deficiency or nitrogen toxicity. Hope it helps.

Thanks man, i did have a magnesium deficiencie just before flower, ended up stopping the calmag and upping the PH.. seemed to work so far but spotted this today.
I will look into detail at cannas range for calcium and meganesium amounts.
Thank you for your input mate 👍👍
All the best.

The other 4 have no signed of sprouting. Are the seeds dead or did i do something wrong? Should i ask for refund on the 80% guarantee?

Leaves full of brown spotsMy friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?
