Damaged leaves
JoseTodoLocostarted grow question 3 years ago
I have a problem with one of the plants, the leaves are damaged and some of them had to be removed, the plant is growing too slow. I thought it is related to Cal/Mag but I've been adding it for a while since week 2 and the problem is not corrected

I believe you are correct, ph was way to low. As soon as I saw your pics I was gonna tell ya to check your meter calibration, but then I read your comment about the meter being out of calibration. Lol bringing her back into the 5.8-6.2 ph range should fix your problem. Cheers💨
JoseTodoLocoanswered grow question 3 years ago
The roots are white, I didn't see any issue with them. Last week the PH increased to 6.2, I didn't see the damage increasing that much at that point, I dropped to 5.8 and things got worse even other plants started having tiny spots, so that makes me think it could be the Cal/Mag deficiency because lowering below 6 the absorption starts dropping, so I checked the PH meter calibration and was way off, today after the calibration the water was at 5.38. Too bad! I will increase it to 6.2 within 2 days and see how it goes, hopefully it solves the problem. It surprised me I didn't kill my plants when they were seedlings because the rockwool had to be at 5.5

All your numbers seem to be in chexk for pH and ppm. Thou I wonder if maybe you burned it with that high of a calmag feed. I'm not a dwc grower so I won't have all the answers but how's the root zone look? Pumps clogged or anything?

Brown spotsWhat is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

Bottom Leaves only looking worse for wearHi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.

Calcium deficiencyI already had a question a week ago, now it's easier to see, camera still bad.
But here are some fan leaves which I believe are showing a calcium deficiency.
Calmag is in the post, just waiting for it.
Is it for sure a calcium deficiency only? Thoughts?

Browning between leaf veins!After my low humidity problem two days ago, she seems unhappy and the growth has basically stopped. I realize it should be slowing down at this third week but these brown, dry-looking areas are showing up between some of the leaves, the ones in the center being the worst. Thanks!

Upward Curling Brown Leaves/Nutrient Lock Out?I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light.
Leaves are curling upward and browning. Not crumbling yet but look like they will be soon.
Both new and old growth is being effected.
Maybe the Mineralized Phosphate was too much.

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔)
The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight
