Is it Light burn, nutrient burn/deficiency or overwatering? Whats going on with my plants?

Hey there folks, Due to availability issue i made this soil myself by mixing 3 part potting soil with 1 part kitchen waste compost, with 10% coco-peat, little bit of chicken manure and some stone chips. Soil and water PH is about 6.5 - 7.0. These babies were popped out of soil on 22nd Oct so yeah they are three weeks old. I am growing them in a 3x5 closet. Right now its 18/6 light cycle. Temps and humidity levels are around 25c and 50% respectively. I have installed one pc fan as exhaust and one blowing on the plants. Using CFL on one plant and DIY LED light on the other one. But recently I accidentally overwatered my plant which is growing under LED, and i also noticed that the LED light was only 1 inch away from top leaves so i guess it was too close (now moved 2-3 inches upwards from the plant) and now the top leaves look they are nute burn or may be deficiencies i dont know, gave them a little bit of chicken manure on the beginning of 2nd and 3rd week. I see some pistols coming out from stems do you think its showing sex? Please have a look and let me know whats going on what should i do its my first grow I don’t want it to go wrong. Please help

Hi @Jake_93 - you pics didn’t upload. You have to wait until it says it is done uploading, or it doesn’t show your pics.

@raustin your expertise please?

my first thought is nute burn, but then i remember you and think - phosphorus deficiency?

That looks like nute burn to me. What are you feeding?

I think I’ve read somewhere that chicken manure is too hot for mj @raustin?


I would water until runoff, then check your PPMs. If it is to hot then do a flush to bring it back into correct range. I don’t grow in soil so I’m not sure what your PPMs should be but someone will know


Yes, chicken manure can be hot. I would flush to get PPM down to around 500.

ive used chicken manure to make a tea for foliage spray on outdoor tomatoes - explosive growth. maybe use ur chicken manure for a tea and feed it that way. i think the tea brew process softens it for the plants

I re-uploaded them :slightly_smiling_face:

How can i give them more phosphorus? Any organic amendments that you might recommend?

bloom fertilizer

something with pk and no n

I was feeding them some chicken manure as a soil topping. I just scraped off all the manure from the top. Can i feed them with bat guano tea? Does the guano have to be composted first?

Alright thanks i will look into that.

How do i check PPM, does flushing means plain water ?

usually flushing can be done with plain water then pH adjusted water after the goal ppm is reached.

you need a ppm meter to measure ppms.

Hi - when flushing, the total water you want to run through your pot is 3x the size of that pot - 5 gallon container gets 15 gallons. The goal is to reduce the ppms to less than 1000 (there are differing opinions on what this should be, and it varies a bit by the age of your plant veg/flower cycle).

If you have/get the digital ppm meter (everyone one growing should get one), when you water next, it should be watered to run-off and when it flows out the bottom of the container, collect it in a small cup. Take readings of its pH and ppms. This information is the simplest method to understand the health impact of your growing medium on your plant. You should also measure the ppm of the water going in, along with pH

I would hold off on adding any nutrients for the time being.


You need to figure out where your soil is at before adding anything. You could just make things worst by adding something.

Thanks for this information i will definately buy a PPM meter asap. I will consider adding more nutes after monitoring PPM and PH.
