Light stress or N Deficiency?

Just increased the brightness of my lights and switched the plants to 12/12 a few days ago. Wondering if this light green on top of my plants should be of any concern?
i ordered a lux meter so I can start measuring the light.
Any thoughts are appreciated.

Im going to say she is hungry . Again more info on medium, nutes used. How often your feeding exc. Will help us help you.

not enough details. Actually looks pretty good. Dont fuck it up by doing much. Could easily be perfect next water and a day. How far from the light? Type light and watts? one thing burning too close. ex. perfect is 400 w 1 foot away w correct venting. no reason to give tip yet is real

nuts are pretty close w dark green leaves. nut situation.

Alright

Soil: Fox farm ocean forest with 30%perlite/coco

Fed using distilled water with 4 ml per gal of cal mag.
I use fox farm dirty dozen nutrients at 1/4 strength every other feeding.
I water depending on the weight of the pot. At most, twice per week.


my light is the Mars TSW 2000
I was running it at 40% during veg, now I moved it to 75% and it’s about 24”-30” from top of canopy.

I’m scared to turn my light up any higher.
I will keep on sticking with my nutes the way I have been, thank you!

lay off watering 5-7 days. twice a week they are not drying out enough. You do know this plant likes to dry out before watering dont you? Twice a week watering tells me you don't likely not enough experience w plants in general.

next grow light get to 100 percent after 1st week. move it every couple days up if they show well. you need to pay attention to how close it is to the light. keep a marked stick 1 foot and 3 foot. do u know why? just passing on tips

I don’t water them on a schedule. I wait for the pot to tell me when they are dry. I let the pot completely dry out before I water. At MOST twice a week, since they have been in their final pots it’s about once a week. Thanks for your kind comment.

so let them work up to 100% while still seedlings?
I figured if I turn the light brighter I could move it further away. Not sure on the stick

they look fine. I don;'t do led yet. I have it dialed in. know your light distance to plant tip needs and how far down light goes to produce op bud. example hd 400 watt goes to 3 feet op bud development. thats 12 inches to plant and the next 24 perfect. google that model it shows and dial it in as they approach those areas. ill keep an eye out. this place made me green thumb so i pay it forward....I spend less time doing nothing and thats really a good thing. plants don;t like big hugs and loving from humans. lol

Not sure if light could cause that

This link has some very good information
"https://nrcca.cals.cornell.edu/soilFertilityCA/CA1/CA1_print.html"

The Image below is educational ; might help .

Sometimes leaves turn light green to protect itself from heat .
You might also want to measure the heat at the top where it is closest to the light ,

Does anyone know if I need to scale up to 100% nutrients for flowering?
nobody knows your exact situation on nuts. increase slowly so if tips burn you can back off nuts. Too much water before drying out can cause tip burn as well. When I see newbies with yellow tips or burned think adding nuts to correct make me cringe as they are feeding failure when its plum overwatered soggy. remember the less is more and better thing. so yes sure 100% if you were at 90% last feeding.

Is there a certain soil/nutrient line you would recommend?
This is Halman 9000 to Joshket

I am a newbie and growing Wildflwers and vegatables from seed .
I just restarted my garden after failure .

This time I am focusing on NPK and PH .
So far it is looking like Both NPK ( balanced ; like 5 - 5 - 5 ) I make it very diluted , The smaller the plant the more diluted I make it . I now am adjusting the PH of my water and grow medium , for the first time . My tap water is a PH of 8 to 8.5 . I add very dilute Tap water with very small amount of Vinegar until my until my meter shows a PH of 7 for the water I will use on my plants. My sprouts are already looking better .
They say the two mistakes new growers do , is putting too strong of nutrients in the soil and not adjusting the PH .

One way to get good at nutrients and PH is to grow some Wildflowers or Mint plants or Pepper Plants in a small experiment and try different nutrients and PH adjustments , If you think your Fox Farms is burning your plant roots , then you can mix the Fox Farms with some PH neutral grow medium and try growing some house plant either from seeds , or a small plant from the nursery , and take extra time to get the PH more neutral , and not too acidic or to alkaline . Also try using some of the grow medium your using and mix it with a neutral grow medium , like neutral Organic garden Coir . So when I grow seedlings , I focus on using only NKP , very diluted , and I focus on adjusting the PH of the grow medium .

If my plants make it healthy for a month , I start thinking about secondary nutrients .
I have been having a lot of trouble growing roots , so I make a very diluted NPK solution , and spray it on the plant . My theory on doing that is that N , P , K and fairly mobile , and hopefully the NPK is traveling down the plant into the interior of the roots . I also feed the grow medium with diluted NPK . Some people say it is ok to have strong nutrients in the soil at the seedling stage even though they can't take them up into the plant . I am not experienced enough to try strong nutrient levels in my seedling grown medium .

I think if you see a deficiency in your new growth , you might have a deficiency in a immoble nutrients . It is more likely that your lights are too close and excessive heat is present on the top part of your plant .

I think my problem with growing roots after the seed sprouts , is that I was watering with PH 8.5 tap water , and also I was not feeding the seedlings with NPK balanced ( like some of each ; I am using 6-12-6 , but I thinkj 1-1-1 or 5-5-5 would work ) .
Also , buying some large house plants , and learning how to get them to look perky and shinny . These were old houseplants and the soil smelled spoiled and so I did a little flush with water , and I feed them with water and very dilluted 6-12-6 , and some of the plants started flowering a week later . Also the leaves reached out and looked erect , and also the house plants became shinnier .

This is my redo of my garden . all the pots have seeds planted and they are starting to sprout . The two big plants are survivors from my last failure .


PH7NPK (1).jpg

I also am adding very diluted Calcium , Magnesium and Two basic Amino acids to help calcium uptake .
The 6-12-6 is an indoor plant fertilizer that has NPK of 6-12-6 , but the back label says it has some secondary nutrients and some small amount of some Elements . It has some Sulfur in it whcih is good because I think a small amount of sulfer is good for seedlings . I forget why a tiny bit of sulfur is good for seedlings . So I guess that some of the indoor plant food also has small amount of secondary nutrients , some elements , and perhaps some small amounts of micronutrients . They key for me is giving the seeds and seedlings very dilluted balanced nutrients to feed the plant with . Also I am learning that giving a little water at a time works good , treating water like a nutrient and not to over water and make sure you give some water if the soil is dry , implying the plant has been neglected by someone and bringing an almost dead plant back to life . I took 3 old plants that were neglected and almost dead , and brought them back to good health .
