New fan leaves light green tips

[JoJolewinsky]

Hey guys, as the title states my new fan leaves coming in are coming in with light almost lime green tips just wondering if anyone has any insights into what this could be?

I'm using hp promix, I mixed in gaia green worm castings during the transplant following the directions for mix to medium and I gave the root ball a 1 teaspoon dose of mycorrhizal and added in a bit of perlite myself to help with drainage a bit more. I'm also using advanced nutrients grow micro bloom and following the directions on the bottle, 14ml of each to 1.5 gallons of water for this stage of growth. Water is pH at 6. I'm currently doing 1 feed with nutes 1 feed without. I'm growing in 5 gallon fabric pots so it's fairly easy to tell when the bag starts to get lighter and needs a watering so I water based off that, about every 2-3 days depending. Any recommendations as to what might be causing this are much appreciated. I've also found 3 boxelder bugs in my room since starting this grow, not to sure if it's possibly them sucking the nutrients out of my leaves. I'm using the areolight 100w led grow light and it's 22 inches from the canopy. Day temps between 78f and 80f. Nights temps between 70f and 73f. Humidity between 55% to 60% vpd between 1.4 to 1.1

Could be nute burn. I don’t know if it’s a shadow but some of those fans look pretty dark. What is the intensity of your light set to % wise?

80% 18/6hr

80% 18/6hr

Download the Photone app. It’s the black logo in the screenshot, second row. 80% seems like too much for veg. I run mine which are 150 watts at 35-45% for veg and that gives me about 500 PPFD at 18”. You should be somewhere in the range of 300-600 for veg.

Fuck me alright it's telling me I'm anywhere from 800 to 1000. Gonna try and bring down that intensity. Appreciate you!

That would be good on the high end of flower.

Just realized it's telling me I need a diffuser, gonna have to run out and grab some white printer paper. Got the intensity set down to 45% for now. Guess that other reading was a bit off as well, wether more or less. I'll keep you posted. In terms of feeding schedule would you recommend moving to 2 feeds water 1 feed nutes rather than the 1 on 1 off I'm doing currently?

Light green tops are completely normal. Light green tips, not so much. If I only see that on tips on top canopy I presume a lighting issue.

Me personally, I’m on the Mega Crop train in 10 gallon soil pots and I feed at every watering which is usually twice a week or so. If you want more info on that DM me and I’ll pass all that along.

Looks like light stress. You've already adjusted the light intensity down and should see improved new growth.
