Flush or wait?
eaf620
started grow question 6y ago
I suspect the ph is off. Should I flush it out with some balanced water or wait for it to dry up? On the bright side, my first attempt at hydroponics is going well!

great thing is you can replace entire reservoir... ensure it's pH'd and a proper balanced diet for plant.

Yellow Colour
Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?

Discolored Older Fan Leaf
I’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?

Lower leaves turning yellow and getting crispy
Lower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!

Brown spots, PH in run-off is in the high end (6.5~)
I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?

Drooping leaves
The water pH wasn't right before but it's been at 6 for the past 5 days and the leaves are still drooping and seemingly yellowing albeit at a snail's pace. Water her every 2-3 days + 0.5 ml of feed once a week so not sure what the problem is currently? It's an organic grow.

Yellow leaf
I’m 6 weeks into a 7-8 (suggested) flowering stage. Some of the lower leaves have gone yellow. Is this signs of the plant ending it’s run or something to be worried about?

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Can this stretched seedling be saved?
So, my first seedling spent a few days w/weak light and got stretched. I then started “Shorty”; both outdoors the last three days. I buried “Stretch” 3/4” deeper. Is “Stretch” (the first plant) totally fucked? Anything else to do? 1st pic is Stretch, 2nd pic is Shorty.
