Langbeinite is an organic amendment that has potassium, magnesium and sulfur. Its a naturally mined crystalline mineral that does not alter the ph.

What are these leaves saying?
What do you think these symptoms are saying? PH was low for a couple feedings before this photo (4.9-5.4), could that explain this? The coco doesnât stay too moist so I donât think itâs overwatering. Could it be underwatering? I do have roots trying to get out the drain hole now

Main stem snapped
LST gone wrong. Main stem snapped after the last LST session, must have happened a while after adjusting the ties. Taped the damaged area. Will it recover? How long would it take? It looked like only 25% of the stem was holding it together. The area got red/brownish.

One plant is looking bad but still doing it good leafs hanging it looks strange
If you can see on the picture one plant is looking a little bad. She grows in the length better than the other one but the colors looks a little like yellow or lightgreen and the leaves hanging down and feels hard or raw. But she's still doing it good! Over feeded? To much water?

Can you help figure out the deficiency and what to do about it in DWC? The lower leaves started to display these symptoms. Ph levels are in range and I last fed them yesterday (10ml calmag & 10-40ml of pure blend depending on their ppm) Thanks for all your help growMies! đđŸ

Crispy leaves?
Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.

Defoliation of Fan leaves. The COBRA's growth structure is very tight nodes with large, Indica-type fan leaves. The largest one (3rd pic) has tripled in size from the last photo. I have been bending the leaves under side-branches. Can or should I cut them off to allow light in?

Yellowing tips on new growth? Raspberry Kush Auto
Started to notice yellow tips on Raspberry kush on the new growth. Could this be from over watering? Or should I start adding small amounts of nutrients to her feedings? The soil they were planted in was used for 3 weeks in another grow when I found out they were male and removed
