Need help - I have weird burn on leaves during my vegetative state

markk1244 · 2025-03-12T05:25:31-0600

Hey guys,

New to growing here. I have an indoor growing tent with a Mars Hydro TS600 LED Grow Light in a 60x60x140cm tent using an organic soil in pot method. I'm in the vegetative stage but have got strange burn in on my leafs. I'm wondering have I messed up something with my NPK ratio? such as adding too much fertilizer? Is my LED light too close to the plant? I have been monitoring the humidity closely so I dont think its a temperature or humidity issue. Any help would be great! I'm very new to this and am worried I wont be able to correct the burn-in like issue.

Thank you very much!

it looks like a nutrient deficiency to me, yellow leaves. It could be a nitrogen deficiency

What’s in your soil mix, and what have you been using as fertilizer. It’s hard to tell without any info about the inputs and the other possible factors at play. Also, what are you using as a water source?

Edit - that white spotting on lower leaves may indicate something like an infestation of thrips or mites too.

You got bugs man........and a possible calcium deficiency.

Cal/mag deficiency: brown spots
Nitrogen deficiency: pale yellow leaves.

I'm going with likely calcium deficiency, and definitely bugs!

Looks like at least thrips, bug-wise, Calcium deficiency or pH lockout going on.... Soil looks bad. You probably vectored in all kinds of critters from some random outdoor garden soil or something.

One thing a lot of inexperienced growers don't understand is that weed will "survive" under a lot of bad conditions, but, the idea of growing it, indoors, is to provide perfect conditions and then maintain them throughout the grow so that the plants flourish and exceed what they would do under imperfect conditions. You're just providing imperfect conditions, indoors and your plant looks like it's just trying to survive at this point.

Coming here to ask advice is good for starters. Watch some grow videos. Read some articles. When you come across some growers getting results like the ones you want to get, then copy exactly what they do. Don't grow auto flowers or fast flowers, either. Stay completely away from them. That's my advice.

If you decide to start over....Get some Fox Farm Ocean Forest soil, a couple few 4-gallon plastic garden pots (I'd avoid the cloth bags)....Mix in some extra perlite and vermiculite for drainage....weigh the containers both unwatered and watered so that you know when to water or not. pH your incoming water and check the runoff pH, too. Find a good synthetic fertilizer regime like Jack's 3-2-1 system and follow the instructions. Avoid the "Joy Juice" "Super Piss" "Bud Hardener" bullshit. Stick to the basics.

I'd lean towards slow light burn on top of calcium deficiency and thrips.

If it were Nitrogen I'd expect it to work from bottom up and not biggest fan leaves first.

Is the light on 100%?
How many hours?

Calcium and nitrogen deficiency.

Thanks for your help, how should I correct a nitrogen deficiency?

I am using a soil mix called Scotts Osmocote Plus 25L Tomato, Vegetable & Herb Premium Planting mix.

For fertilizer I am using Charlie Carp all purpose fertilizer. I am using bottled spring water.

I am using organic soil and growing in a tent indoors, I wonder how the bugs got in? Can the bugs be in the soil? I have not seen any on the leaves.
How should I correct calcium deficiency?

Thank you, this helps isolate the issue. Do you have any recommendations on how I can bring the plant back to good health?

Strange that it could be bugs, I havent seen any but maybe they're in the soil in the pot?

Thank you for your detailed response. Do Thrips exist in the soil in the pot? I havent seen any on the leaves or in the tent. Unfortunately I only have the option to grow inside in the tent I have. I am using a soil mix called Scotts Osmocote Plus 25L Tomato, Vegetable & Herb Premium Planting mix. I have read that soil that is good for tomatoes is good for weed. For fertilizer I am using Charlie Carp all purpose fertilizer. I am using bottled spring water.

Do you think I can bring the plant back to good health? If so how do you think I could do it?

Need help - I have weird burn on leaves during my vegetative state
