Hi ! Misschien wat teveel voedingsstoffen, maar hoe is de afloop? Het lijkt eerder dat ze niet goed meer worden opgenomen. Check dit en je ph waarde. Veel succes!🌱

Iron Deficiency?
Appear to have an iron deficiency, perhaps as a result of lock-out. May have been triggered by light stress or environment changes. Living soil media, watered with rainwater, supplemented with compost teas and organic soil drenches pH to 6.5. Seeking advice as to how to correct

Yellow-ish leaves and brown spots
I ran into a small problem. The leaves of my RQS Critical are getting quite yellow and brown spots appear on some of the leaves. PH is kept between 6.1 and 6.5 while growing in organic soil. I feed according to the BioBizz schedule. Curled leaves have already been fixed.

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.

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Younger leafs are discolering. What to do?
This week my WW started getting pale? I tried to look on examples on the net of discoloring leafs. Is this a Zinc defecienty? She seems to be struggeling a bit because of the colder nights. Could this also be due to that? Looking forwards to your answer, dear question replier!

Yellowing leaves.
Yooo! I have a few lower leaves starting to yellow I’m pretty sure its because the plant has switched all the energy to bud production so my question is, is it ok to defoliate the yellowing leaves at this point?

Bottom leaf turned yellow with brown on edge
Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

Am I overwatering these seedlings? (Coco Coir) Please help, Thank you :)
These seedlings are about 3 weeks old in Coco coir. I PH the water to 5.8-6.2 everytime. I was watering every 1-2 days as the top soil dried out. Have I been overwatering? How much/often should I water them at this stage and should I wait for them to perk up before transplant?

Why this happens? Leaves turning dark to yellow
After water + applying fertilisers BioBizz flowering week 4 (see chart) the leaves turned dark and in a few hrs started yellowing. The runoff EC usually is a little lower than solution EC. pH around 6,25-6,5

leaf yellowing
I have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.
