[Just250]

Hey guys I'm new to this I have a box in my closet 1 foot by 1 foot all foiled up have a little fan blowing on the plants and about a foot away I have a 250watt HPS LIGHT. I water them once mayb twice a day have the light on 12 hours a day. The plants are only 50 mm long and I had a MP light in but they didn't grow and started turning yellow so I put my HPS light in and now there turning yellow and starting to sag and die????? I think my ph is normal. Is my light to close? Is it to hot for the plants? I dunno what it is please help!!!!!

Isn't 1 Foot pretty close for a 250watt HPS, you may be scorchin' em

you need to make some amount of reading xD theres a lot of different things what can be wrong.

I understand and have been reading alot but I just need think it's something small like not good enough ventilation or the lights to close? How far away should the light be? I mean it lights my hole room up through the gaps even when my closest doors are closed!

Hi umm are you feeding with flower A-B also use a MH bulb and have your lights on for 18 hours flower and bloom(bud) 12 hours a day. When feeding- feed today and make sure its kinda heavy then when pot is light repeat again the when pot is light then just strait water for the next 2 watering then feed once then just water 2 times then feed 2 times and so on that way your always getting rid of all salts in your plant ! Oh get a bigger room and use 600 watt and keep light 18 inches away from plant. I hope this helps you. OH and when your plant is about 3 feet tall turn it back to 12 on 12 off and make sure you use bloom A-B and thats when you use HPS light, just ask how to mix :)

wow thats really good, but i swear the long i leave the light on the worse they get, can i pull them out an dput them in some kind of new potty mix or will that shock them and kill them?

Watering 2 times a day is way too much
Im new to growing aswell but ive read up alot and everywhere ive read it says to water maybe 2 days a week and 2 of mine are growing fine i accidentally burned one but its healing perfectly :rasta:

It could be a number of things. If your plants are getting scorched from the light, the top of the plant would be most affected, but I have to agree with the above poster, 2 times a day is waaaaay too much water. You're probably drowning the shit out of them. I water about once, maybe twice every 7 days. Twice a day is too much. Allow the soil to dry out, then water again. I have learnt so much just from reading this website. Read read and read some more. Include some pictures if you can as diagnosing a plants problems without one, is like a doctor reading with a blind eye.

i agree i have been growing for a while now and twice a day is too much i suggest that you keep a bucket of dry soil the same size that you have your plants in and compare them when they feel just a little heavier than what the dry one is its watering time or you could get a moister gauge from walmart or really any store that has a garden section :rasta:
