Not too worried, but is it ok, yellowing of lower leaves?

Heres a pic, I just switched to 12/12 with 4 42w 2700ks yesterday. Been using SPT th last week, been watering every 3 days with peters professional 30-10-10 1/2 teaspoon per gallon. The burn spots are from foliar spraying, done with that until lights out at least.

It's just the bottomest two sets that are gaining a more yellower color along the edges and tip compared to the rest. It may be hard to see in the pics because it is still slight but I think it's increasing daily.

Should I try to correct this or just leave it alone, overall the plant is
fantastic looking and is growing well.

Thanks.

its natural for fan leaves to get yellow during flowering, so as long as the buds are growing and the ph, light, nutes, water, etc is right you should be ok. i was worries too when this 1st happened to me but you should be ok

it's also regular for the lower leaves to age or yellow as they move farther away from the top of the canopy... if they aren't taking in light anymore I usually cut them off anyway.

It should be fine. You shouldn't cut leaves if they are yellowing. When the leaf is completely dead you can take it off.

this is just a suggestion, your current npk is 30-10-10.. in flowering you want the N lower and the rest higher example 5-20-10 etc...

Guys my next upper leaves are starting to droop and turn slightly yellow, what the hell is going on is it not enough Nitrogen or too much!? The new growth is fine and so are the smaller leaves coming from the nodes.

Your plant is changing chemically, from veg to bloom, its using a lot of stored energy during this, if it cant get what it needs from the soil it is metabolizing itself, using the least useful leaves first, lower fan leaves. some yellowing is expected, and i never yank my plant untill all the fan leaves have yellowed and died, bout that time its about 60 to 70% amber and good smoke.

no way man im almost 100% thats the beginning stages of nute burn,

if you look at all the tippy tips of the leaves you will see that they will slowly get crispy, usually starting from the bottom up like you have there


trust me cuz i nute my babies right up till i see any signs of slight burn on the tips then back off. better reduce the nutes a lil or they will burn more


u will see it i bet every tip on every leaf on your plant is starting to have the tinyest little brown crisp to the tip of it by now

check it out

Not all but a good number of them, I think it is burn, do i just back off and just use water or specifically flush it?

Ok, heres some photos.

As you can see the two most bottom fan leaves are turning yellow. I have had this happen already with the very first set of leaves about a week or so ago (clipped them).

The issue is that the next set of fan leaves is starting to droop as well and begin to SLIGHTLY turn yellow just like the set beneath it.

What is wrong? Please assist! Added mylar yesterday.

wiat a min if they are getting pale it means they dont have enough fertz so i could have been wrong, nute burn doesnt really make them turn yellow they turn brown and crispy it may be you need more ferts, the leaves are not supposed to yellow until the very end of flowering.


i dont do soil so I cant help you about how to fix your nute issue, but pale leaves means not enough ferts, do you have a ppm meter for soil?

as your plant gets bigger and flowering you are supposed to increase the nutes too, or they will obviously not have enough to keep up with thier growth.

you need to have a way to test your ppm in the soil. then if the next day you see your ppm lower than it was the day before it means your plants dont have enough. i think, but thats the rule for hydro. may be diff for soil.

I thought it was underfeeding too because the leaves are slightly drooping, but the new growth is fine (it's taking the nutrients from the old leaves i think).

Yesterday I added ozonated water, some molasses, the day before I added a concentrated dose of nutes.

On my bag it says 1/2 a tsp per gallon I followed this advice.

the first feeding I ever gave it was 900 ppm, but the water was VERY blue. I thought it was too strong (was like 3 or 4 tablespoons in the gallon to get it to 900 ppm.

Should I follow the instructions on the bag or follow PPM amount? I don't ge it.

Yeah up the nutrients and you should be doing fine. Somthing with a high Nitrogen level. It will stop the yellowing. The leaves that have turned yellow will not go back to green, the will most likley tunrm more yellow and drop off. If you dont start feend it more the yellowing will comtinue all the way up your plant and it will die

I would just back off a bit what the instruction say on the bag just to make sure not to burn them. Work your way up from there you will see results in a day or two

i would def. change nutrient package to a low nitrogen high pot. and phos. but besides that looks good. yellowing just means the plant is using up the sugars stored in those fan leaves to increase bud development. so don't sweat it unless yellowing continues to grow. but a good looking plant 4 sure.
