having a nutrient problem thought it was a phosporus deficiency

help!!!! having a problem with 3 of my plants, their upper fan leaves are turning a deep green color and sagging from the middle, i'll try to post a pic

using neutral soil and adding nutrient rich NPK veg food about once a week about every 3 waterings, just have them growing on the balcony with a fan blowing on them, temperture's keeping about 23-27c during the day and around 17-20c at night, planted them about 8 weeks ago

help!!! i thought the problem was a phosphorus problem, gave them some phosphorus and it hasn't helped. any ideas????

what soil are you using? and what kind of water do you give them? tap water?

i think you should give your plants a little bit more wind. it might just be the picture but your plants stems look really skinny

the soil i'm getting is just some chinese name brand, i have no idea which ones are the good ones and which aren't, can't read chinese that much, just which are ph balanced and which aren't

as for the water, i use tap water, oh and i took your advice and added 2 more little fans to get the air circulating more, i checked my plants and was keeping in mind the air flow and sure enough the ones directly in the path of the big fan are the biggest, good call buuuuut still wondering about the possbile deficiency of those leaves

cool cool but personally i have noticed that cannabis plants dont do that good with tap water. go to the store and bring a pocket full of coins and get some pure good clean water. guaranteed will help

fox farm has the best organic soil. too bad you cant read chinese hahaha

and the nutrient problem? thoughts?

if you have a good soil, to be honest you dont even need any nutes. the plant is a weed, nutes just make it grow stronger/bigger/faster

oh what i meant to say is i think its your chinese soil lol but its all good next time make sure you good good stuff. soil and light is everything
