My seedlings have a deficiency

[Travismilne89]

Please let me know what my deficiency is. I'm thinking ph is to high? Highly appreciate any help!

Most common problem is overwatering, seedlings rarely exhibit deficiencies. I suggest getting a pH meter from HomeDepot for 15 bucks and checking your soil. Somebody will chime in that those suck; I have tested them against two different chemical kits, they work fine, and the results correlate with the kits. They will definitely detect an out of whack situation, they won't tell you whether it's 6.2 versus 6.4, but that doesn't matter for most problems. Use them in moist soil, and let them sit for two minutes before reading. One of my threads from earlier this year shows the results of the test.

Your cooking them with to much light

I really appreciate it. I have some ph down coming. I'm at about 7-7.5 so I definitely have to adjust that. I'll post the results.

My two other alien OG are coming in nice and green with 0 issues. I'll post those as well. Same lights. They came in way later but they are in the same fox farm ocean soil. With RO water humidity and watering.

What light and how close?

It's the Marshydro 1000w. About 4 inches away on 100%. Think it's too much for the seedlings?

 

[Travismilne89]

not on 24/7. Meant they are turned up 100%

Jesus dude back that off to like 30 inches.

I don't mean to sound harsh but I hope they make it. Looking at at least a week of stunting if they recover.

Let me save you some future issues with lights.

Download light meter by my mobile tools dev.

Seedlings 5-10k
Veg 15-45k
Flower 45-65k

Start on the low end of each and slowly increase like 3-5k every few days to a week but stay in those ranges and always start at the low end.

 

[Travismilne89]

Wow!!!!! You don't even want to know what they were running at. Based on what you said I'm not sure how they even sprouted. I am now sitting at 10k right at the plant. I'll post an update end of the week.

They were maxed out on your app I will tell you that

Probably over 150k lux imo

Thank you for your help! I'll let you know how it goes.

I show ~3k if I set my phone down next to my sprouts.... maybe I should try moving my light down a bit.

yeah red leafs and stems which only have red spots where the light is most intense

i have fully dimmable lights but i just leave them at 100% and
adjust the distance from the plant... i dont measure light intensity but i aim to have some fan leaf stems turning red where their exposed to light. imo thats the sweet spot, if you have more then 1/3 of the leaf stems responding back it off a bit.
]mars hydro 2000 watt tsw: at 100% approx 2-4 feet from seedlings, 18 inches- 26 inches away from a vegging plant and 12-18 inches away from a flowering plant

at 4 inches my mars tsl 1000 reads over 200k lux... iv been flowering around 100-120k lux at the top of the canopy, do you think this is to much? they are not showing any signs of burns on the leafs but the odd fan leaf has a red stem where the light hits it.

Something is wrong with your meter. That's like sunlight at peak hour for the entire light cycle. Do you have pics of what the leaves look like

im using a light meter app on my phone, both the plants in the photos are auto-flowering. the lux measurement was 100k on the younger plant and 150k on the older one. the older one also got slight nutrient burn a couple days ago, had a heat wave and my ppm jumped overnight. they also get 2 hrs of UVB radiation a day... haven't and wont be measuring that lights intensity :D

Which app? I see a tad of light stress bit nothing bad. They look good.

The apps use the camera light sensor so maybe it's the phone but for shits and giggles try light meter by my mobile tools dev
