First grow need some advice

Hey guys

This is my first time growing and i could use some help with some kind of deficiency, I've tried to look up some pic's of deficiency's but they all look pretty similar to me (im color blind) I'm growing in a 4x4x7 grow tent with a HLG 260w Rspec XL for veg and will add a 2nd one for flower.im using micro/grow/bloom ph at 6.2 ish. temp is 81f running lights on 24/0 any advice would be much appreciated. Thanks.

I'm no expert but to me it looks like that may be nitrogen toxicity

I’d agree with above. Because of the leaf clawing.

Turn your light schedule down for at least 4 hours maybe even 6 of darkness. You can veg at 24 but if you’re having issues I would cut it down until you get it under control. Just a suggestion and my opinion.

what is your medium?

I'm glad I caught this thread. I have 2 plants that are starting to show a bit of the same issue. I thought maybe those two didn't like the tea I was spraying with. I'll pull these two out for a few hours every night and see if it is indeed 24/0 veg causing it.

Thanks for posting!

I’m not saying the 24 hours is causing it I’m saying it’s giving the plant no rest. Which is fine if the plant is in tip top shape. Even then it’s debatable.

We need more details to nail down what’s going on

thanks for your in put everyone I decided to flush my plants, I'm going to cut back to 20/4 light and use 1/3 or 1/2 nutrients on my next feed hopefully they will be alright.

N tox presents as dark green leaves with what is termed "claw". You don't have N tox. The attached pic is one off the net of a leaf needing Magnesium. Have a look and tell me if you think your plant looks similar. Buy some Epsom salts and use 1 tbsp/gal water. Drench about once a week until you see improvement
.Incidentally, don't flush your plants. Its not a good idea. Flushing is for Hydro growers. Soil growers that flush are just confused.

agreed looks like mag issue

in fact its one of the easiest deficiencies to diagnose because its the only one with interveinal chlorosis

I did not end up flushing just watered well and added a little cal-mag and did a foliar spray with cal-mag as well.

Can you expand on that a bit?

The idea is that it improves the burnability of the buds because there aren't as many salts in the finished buds also improving the flavor. But it's all heresay. Folklore. Passed on from grower to grower and much of the time it's by forums such as this.
Now I've only ever grown in soil myself. What I'm telling you is strictly my opinion. However there's some new research that backs me up. Here's a High Times article that you may find helpful. https://hightimes.com/grow/new-research
Ed Rosenthal, a long time Cannabis enthusiast and writer has several books out that include information on flushing and Ed says it's important.
Ed knows his shit. But in the end there haven't been any side by side studies that are definitive enough so that flushing becomes standard practice until now. I think the High Times piece though should gain some traction and maybe in time the flushing debate can be put to rest. Hope that helps.

Thanks for the link! I'll check it out and see which rabbit hole it'll lead me to tonight.

Looks like you have a few things going on but reducing your light hours from 24 to 18/6 will hep with the light stress.
That sort of LED and 24h light will do that.

I've turned the light down to 75% from 100% and moved it up a little bit, also have been spraying with cal-mag foliar spray and epsom salt foliar switching between the two. I have watered with cal-mag once so far, the plants are looking better already. thanks everyone for replying.

Can anyone yall help me out on what this maybe...

@XtremeGrow
Looks like N toxicity with the leaf being so dark. Need a pic of whole plant

maybe its just the pic? Need a better pic. Start a thread and people can help you.
