Yellow leaves with blackish dots help needed

[awhir]

Hey guys whats up ? I have 2 super skunks(feminised) growing in a greenhouse , they are around 2 months old now and about 5 feet tall . They are still veg'ing . I water them nearly every second day or they get a small amount each day . I gave them too much nutes about a month ago and one of the them got baddly burned , he recovered tho .I haven't given them any nutes since. they are planted in vermiculite and pertile with tomato soil . In the past week their leaves have started going yellow and now some have the black dots , does anyone know what is causing this ? Il put pictures up too

thanks.

The yellow looks like an N def. The rust looks like root problems.

I'd water based on need, not necessarily the number of days.

Are you growing in containers? Let em dry out before you water again. Are your containers big enough?

There's always the possibility you have fungas gnats. Constantly wet soil is a breeding ground for these. Crushed up mosquito dunks applied evenly to the soil surface will keep these under control.

How's your water quality?

Best wishes.

I would certainly start out by feeding again, 5 ft tall plants in a container with no ferts for a month. They're probably feeding on themselves to keep the tips viable.

thanks for the reply , I put them into bigger pots 2days ago so there roots should have loads of room to grow. I just watered there with a small mixture of urine , I read that was supposed to be a good way to help N def , i used around 300ml urine/1700ml water would that be enough ?

Several urine threads here. Most say 1 part urine to 10 parts water. Yours is almost twice as strong. Try not to use morning urine, it's a little too potent.

Have you tried getting some nutes instead of using your urine?

Sorry, never used baby bio. Have you checked google?

I couldn't find anything concrete so i just gave them 1/4 of the recommended dosage. I gave it to them today how long do you think it will take to see any difference ?

your plants are hungry and eating themselves as someone already said. if you use urine start with 10-20:1 ratio and adjust. its very strong.
