These plants are a couple weeks old, they are in regular potting soil mixed with a small amount of fox farm ocean. Any ideas what the discoloration in the leaves could be from?
Time to transplant my friend @Aricci
If you haven’t done so, it is best to place clear cups inside opaque cups because roots don’t respond well to light exposure.
Here are a couple of symptom charts for you to look at to determine what is going on.
I can’t tell from the photo but @Reed71 may be correct.
Regular potting soil is a very broad term. Although I do not see it being the problem the more info the easier it is to figure out the problem.
I will go with clear cup light pruning the roots and a crowded cup.
I plan on it today. Ive got 5gal fabric pots. And theyre old enough now that i can use straight foxfarm ocean right?
They started doing it almost immediately after sprouting. So i dont think the clear cup would be the cause. And the potting soil was miracle grow potting soil
The MG is to strong for seedlings extremely high in nitrogen some strain can handle it some can’t. i would say that’s the issue but it would most likely grow out of it
You can go into the FFOF, they may get transplant shock, tho. I’d do so now, if auto flowers. Once they start shooting pistils, in my experience, you have maybe 3 weeks before full flower starts. Stunting or damaging from transplanting into new soil could hinder your yield. But doing so quickly will allow some recovery time.
WAY HOT!!! Time to up pot and back off the nitrogen.
After hearing the soil mix I would like to chine in again
I do not think the OF is the problem. At 2 weeks in full conversion has just started.
Now the MG is different. It does have mineral nutrition available.
When plants are at that stage you water away from the roots. The humidity in the soil from doing this is high enough to power the grow however if you get wet water at the roots in a mineral mix the nitrogen bloom can burn a plant.
I have stopped worrying about burning a grow from a soil mix as I have put sprouted seeds several times directly into OF because Using 50-50 HF and OF always petered out quicker and required more organic amendment. The cal-mag load in OF must be much higher than HF as the cal-mag issue with OF was almost 3 weeks later than the mix.
Whats OF and HF?
Fox farms soil - Ocean Forest or Happy Frog
The reason for the discoloration is ocean forest is too hot for seedlings. It will pull through. You won’t have to feed much.
