I’ve just started my first organic Grow and my seedlings were started in FF seed starter with happy frog around the outside.
I have been composting my own soil for when the 2 white widow photos are ready for transplant, I have 2 Northern lights autos going too.
One of the white widows is showing some irregular growth and odd leaf shapes, I’m wondering if this is Boron deficiency but I have never come across this particular issue before so not sure how to diagnose it.
It seems slightly behind in growth but it is still growing steadily, just one leaf at a time apparently.
I am far far removed from organic growing. No help there. Re irregular young leaf shape. I would not be concerned. 99% of the time it is nothing and they grow out of it. I think boron deficiency is a reach. It is a young plant in new soil so it is not something I would expect or anticipate. Also, in soil boron has a wide ph uptake range.
If the unadjusted ph of your water is 6.5 - 6.9 you are right. You do not need to adjust its ph. You still should monitor runoff ph. At least occasionally to confirm the soil is in range.
It looks like your plants will be ready for a bigger pot soon.
Hoping that’s the case! Never used this seed bank before and likely won’t again, pacific seed bank, awful customer service and sent me 2 autos for Northern lights instead of photo and then blamed me for it haha. I realise the irony of stating that on a forum that has its own bank, live and learn.
Edit to add ppm comment.
I would not be too worried about 2700 ppm. I don’t know what you added anything but I use to use ocean forest. I would put a little buffer in the pot when planting seedling or transplanting. I would have monstrous run off numbers. Unless you have watered several times to significant runoff amounts, what can I say soil is soil.
I now use coco - very little guessing about runoff numbers. Other than at first because I hydrate the bricks with a full load of Jack’s. I am just now dropping below 2000 after 40 days while feeding at 800 to bring it down.
Absolutely PH the water before feeding it to a plant. That high of PH going in and the roots won’t be able to absorb all the nutrients. 6.8-7.0 PH going in for soil. Either way 7.8 going in is really high. This is most likely the cause of the slightly less green color due to PH fluctuations. Adjust the PH to soil range from here on out and let her go. This might also explain the higher PPM on runoff, she’s not absorbing anything at a high PH.
That’s good to know although the last batch of water was adjusted, its just that I took it to about 5.2 by accident and had to raise it so I wondered if the excess of phosphorous acid or potassium carbonate was causing some issues
Could be, alot of organic growers use stuff like vinegar and other stuff to bring PH up and down. I have no knowledge on this, but GH PH up and down is a straight up chemical. So treat it as such and use as little as possible to get to where you need to be. What I do if I go too low, dump some water out of the container you just PH-ed and add more straight water to bring PH up again. You have a good PH pen correct?
