Definitely not phosphorus man you won’t have to worry about either potassium or phosphate until flower way later, Right now it’s a nitrogen management game

It was pretty cold last night got around 42* but i do feel like it could be on the critters side because i did see like a small black flie looking thing under the leaves

I’d be sure to go ahead and look at that as many leaves as you can and see if you have an infestation that’s happening there if you do get yourself some Captain Jack’s dead bug That stuff is aces and it usually knocks out the issue in one or two treatments
A cold snap definitely can cause what looks like that wilt as well, But how often are you watering and or feeding nutrients? And what nutrients, also, what soil?

okay cool I’ll definitely check that out and see if my local hydro sells that. I have lost coast neem oil but been hearing bad things about it so I haven’t sprayed my plant with that. I was actually supposed to buy growsafe but haven’t gotten to it yet. I definitely will look for infestation and try to get rid of any critters i see. For nutrients i am using advanced nutrients connoisseur a&b and a root booster. I am growing in coco, i ph around 5.8 and i keep ppm around 600-700

Advance is
Is quality stuff,
Yeah, Neem oil can be hit or miss. There’s definitely better options than that. On my tool, but my tool kit is limited when it comes to Coco, but legit your plant is not that bad off We figure out what’s making your leaves wacky whether it be bugs or nutrient driven. I suspect bugs though you’ll be golden.

Anytime,
But I am going to suggest man I’d be easy on bringing that plant in and out of your house every night you better make sure that you do that shit on time and make sure that you’re not messing up your light schedule for one and two if you do have pests on that plant and then you have house plants, don’t think for one second that they’re not gonna jump ship and find themselves some new cozy homes in your Plants But yeah man, the Captain Jack is truly some good stuff when you apply it don’t forget to get underneath. The leaves too good even spray on top and a good even spray on the bottom and if the plants are larger the stalks as well. Never apply with the lights on always wait for lights to go out and apply it as soon as they do👊🏻🤡

How hot is it in ur tent? How far away are the lights? Your plant is clawing down, seems like heat/light stress, lack of water/ or too much water. How often are u watring?

Your plants look green, dunno about the lack of nutrient. If you spotted an insect like a thrip, you should check ur stems and under flowers before sunrise/sunset. Get some sticky traps and put them in the pot. Grab some Damascus earth, sprinkle it in the soil and on the tent floor around the bottom of the pots. Try to identify/grab a photo of the insect.

Thrips can cause those brown rust spots. I don't think its a deficiency. Try NOT to use neem oil its not good for the buds. Did the insect look like one of these?

Neem is def no bueno.
It works in a pinch if there’s absolutely no other options, but the amount of oil in that shit is dangerous for those plants
I can see why you would think that there was a nutrient excess with the tips of the leaves clawing downward like a nitrogen situation but that’s not what happened here he hit 42° overnight and cannabis will react poorly as high as 55° all the way down to freezing I think that the downward clawing was definitely caused by that because the plants pretty green and there’s no low outward signs in the canopy. There’s any nitrogen issues at all.

I will definitely be careful on doing that might just get a small 5 foot green house on amazon to cover them at night time. Thanks again ill keep you updated on how it turns out with captain jacks 👍🏽
