Plants leaves yellowing, help!

well im about a month into my second grow maybe a little more and 4 of my 5 babys are starting to get yellowing sets of bottom leaves, a couple have slight darkish spots too, just wondering if anyone knows what it may be and how can i control it?

also part was burnt on the lesf by light a while ago thats why it looks a lil deformed, but the leaves seem really pale

your plants r starting to consume itself for nutrients it's lacking are you giving nitrogen? looks like a N def

also since 4-5 plants are doin it it must either be soil/environment/nute issue r u giving to much nutes

defintley not enough nutes then i say cause these plants are eating them up and grew quite the size, getting a 7-4-0 bonemeal today also got a 30-10-10 soil may repot soon

same here...

don't use those ferts. the bonemeal will take too long to be absorbed. the other one is too hot.
you want to use a fert for potting soil, one you find in a hydro store or you can use a cheaper one like Schultz. just go easy with it.

ahh maybe thats what it is then because ive been using promix 30-10-10 veg and herb on them all but its usually fine till a month or more in

thinking of grabbing dynagro fp or ff grow big too leaning more towards dyna gro nut not 100% as want to make sure plant havw a great taste at end of the season, and rhanks for advice on bone/blood meal wasnt sure how long would take to absorb

also have a shultz 10-15-10 kicking round but id think that have no use

if that Schultz isn't too old you might use it, but if you have loaded the soil with fert, you might wait a while. dynagro is good. just don't fert for the last week or two, nothing but water to get the fert levels down.

yeah im not 100% sure when to wait to feed next, the yellowing hasnt grow out more leafs anymore also i used a little bone/blood meal round a tsp per plant and one drop of schultz in 2 ltr of water so should fix whatevers going on eventually, but if the 30-10-10 is too hot soil too ill let it eat whats in the soil before i even give it a lil dyna gro, may order a decent sized bottle of it if its makes some good results atleast

That soil is not too hot. Repot with it and don't add any nutes for at least 3 weeks

alright thanks for the advice man, yeah was thinking of repotting i think theyrr only 1-3 gals not 100% sure, got some 10-20 gals though largest and cheapest could find around my area being pots arent worth a whole lot to me could dig holes in the woods too

They look like 1gal pots from the pic. I'd go to a 3 gal pot

Nothing wrong with 30 -10 -10 its same as 3- 1- 1 it will work excellent just mix it accordingly start of small amounts and work it up here is 30 - 10 -10 seedlings

thanks man, yeah theyre doing great a little yellowing slightly probably needs repotting from the 1 cause a couple are now in 5 gals and all 1.5ft indica first outdoor gro

I would think they'd be a bit bigger in a 5gal pot don't stress tho, you always run into problems your first grow
