Leaves turning completely yellow

Hi, what’s up

so first i’m growing outdoors and i’m in week 2 of veg and i’m using cocopeat + perlite + dirt + leaf dirt? (i don’t know what its called) and a little bit of organic fert, the plants are getting direct sunlight most of the day (in a field), temperature is 80 to 87 at day and 75 to 68 at night, humidity is at 17% and i can say the wind is good

i’ll get you guys some photos but for now the situation is, leaves are turning yellow and not just lower ones they are growing yellow from the start and older leaves are getting I don’t know what you call it hmmm, like the corners and tips of the older ones are going down and getting inwardish, the stem and veins look normal but anything in between is turning yellow fast, like yesterday the newly grown top leaves were green to light green, now they’re completely yellow

my guess based on some information i gathered around is that this is some kind of nutrition deficiency and i think it might be nitrogen or magnesium or both and since i don't have a ph meter ( planning on getting one next week ) i can’t be sure but i think ph of the water i’m watering with have something to do with this

anyway i’m thankful for your responses and it will help me so much so don’t be shy

this is a bump

The bottom leaves look like they are burned from excessive nutrients and the top leaves look like they have signs of a magnesium deficiency. If you’ve been feeding nutrients then you’ve probably been feeding too much and have caused nutrient lockout. If not, then your soil was probably too hot (overloaded with nutrients) for young plants.

They also look like there in very wet medium mate

have you used this combination before? I suspect here lies your problem.

Also: too wet

if you mean the medium was used before, then yes i grow another strain in this medium 2 years ago and i mixed that with some fert and put the young ones in, if thats bad for the plants, what can i do to prevent damage to the plants

and as for the wet, i took the picture after i watered them so that might be why it looks so wet, and i’m watering them every 2 days at noon when the top of the medium is dried, before that i watered them everyday and i realized the plants dont like it but the situation didn’t change so much, maybe they need more time to recover, and they are under direct sunlight so i fear waiting till the top of the medium is dried can cause underwatering

Buy yourself a professional already mixed Allmix-type of soil and transplant. I don't think they'll make it, or, only with very slow growth.

One of the basic problems when mixing dirt + Coco together is that the small pores of the Cocos are closed by the dirt and then the breathability/airation of the coco's suffers tremendously.

Your pics don't show the soil clearly but judging from I can see it's just heavy mud. But coco should be sort of still "grainy" (esp. the lesser fine ones) and allow the roots to breath.

yes i think that the soil is too heavy for them, i used it for my flowering plants the last grow but i thought the nuts have been used by the plants so i added some fert for this grow

I agree with kass don’t think they will make it in that medium

i managed to get the premix, i’m transplanting them now, btw is there anything special or any trick in transplanting that i should know about, should i kick the dirt of the roots before putting them in the new medium?

thank you for your help and the kind words, you too have a good time growing

Yes I 'd try to manually remove some of it (not all, the middle shoudl stay so the plant has a hold/grip), you can use water to get most of it away

i went to water them this morning, they died, one is sort of still trying and is alive but leafs are damaged

ill use a lighter medium next time, btw what nuts do you use for mixing your medium

anyway thank you for your response and help

I know I can't help you with those plants now but next round go really easy on the water. You should let the medium dry out before adding water and you should never have puddles of water like the first photo. Make sure you have good drainage and lift the pots to feel the weight. Don't water until the pots are really light when you lift them.

Try Pro Mix next time. They don't need any nutes until they are 8-10 inches high.
