In addition to former question
Appoldro420started grow question 6y ago
I am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?

Measure your pH, organic nutes are less stable than conventional nutes. Keep in mind that a bad pH will change which nutrients are available to the plant causing all sorts of problems. At the very least, get .1 test strip. They're cheap and last forever.
Calmag tends to buildup in coco, so it's a good idea to skip it occasionally.
Robertsanswered grow question 6y ago
I would at least try either a 1 ml every other day or .5 ml a day. If you have a soil ph tester I would use it. Ph being off will cause problems. Coco coir absorbs calcium and magnesium. Great for aeration. So additional is needed to compensate.

Plant starting to yellow too fastThe crystal meth has started going yellow very fast. The buds still have at least 2 weeks of growth needed to fatten out and pack the trichomes with thc.. I know it is normal to start dying but isn't this a bit early? Should I let her keep going as long as sugar leaves are alive?

Leaves "praying" after lowering the lampI am in week 4th of flowering Laughing Buddha, 220W LED ~60cm from tops. Today I have lowered the lamp and the leaves started "praying", on one (higher) plant the other, mostly-indica Holy Punch seems unaffected. I am curious, is there too much light or sweet spot and it's good?

Edges of sugar leaves on top cola brownFor two of my plants, the edges of the top colas' sugar leaves have gained some brown color. It showed up shortly after I introduced the grow light on full intensity which leads me to believe it MAY be light burn. I'm also paranoid about bud rot though. See photos. Your thoughts?

Bites or stress?Could this come from any stress? like nut. overdose after/while defoliation? or wrong PH? Because I can't find any flies/bugs which could eat my plant. I count 6 leaves which are "infected". Should I cut them off? And is it recommended to use neem oil at this point?

Deficiency or toxicityStems are really purple, leaf stalks and veins also purple. Something is up. Some leaves starting to show burn spots but not many. She's a bit down because she needs a feeding. Is this magnesium deficiency? Should I be upping my nutes at this point this late in veg end of W9?
