Brown spot help.

An, you are so close to amazing harvest, that if they will lack some shit here and there - it won't change anything a lot. Maintain good watering regime and pH. Ussually people even raise pH a bit, for plant to have harder times to get some elements and force to eat storage. Keep an eye, they will start to drink less, don't overwater, bud rot .... I can agree that it's calcium spots, but from too intense light, from small lack, from pH imbalances or just starting to eat themself - hard to guess always ... Still think , don't care, just push to the End. It should be nice result ! All the Best !

@DrNickerbaucker hi mate I don't see any brown spots however the lighter colored marks on the leaves suggest a lack of calcium and magnesium you may need to add a little epsom salts to your living soil molasses is good too 👍
