I Have A Problem

[wittaker]

Im growing in soil... Using SensiZym from AN.'
My temps range from 58F to 74F.
I'm using a 1000 watt HPS light

The yellowing started about a week ago and now there are little holes forming in some of the leaves.
Any idea why this could be? Help is much appreciated.

How far away is the light from your plant?

Are you flowering? If so, how long have you been flowering ? Can we see a picture of the entire plant ?


cheers

About 3-4ft from the canopy

Mmm too high to be light stress...well good luck man I'm going to sleep. You really should post more info about fertilizer and such if you expect an accurate answer.

Well its in mircale gro cactus soil mixed with miracle gro organic mix. The only nutes I've used have been Bud Candy and Sensizym both from Advanced Nutrients.
I dont know my PH but I use the Brita Faucet filter attachment to watter them
The Humidity is really low, like between 18%and 26%. No bugs that I can see.

You're not adding any NPK? That could make your plants look pretty bad.....before they die.
How about a picture of your whole plant?

I've got ANs 3 part Grow Micro and Bloom, but the plants have done just fine without more than one dose of the bloom and micro. The plants are entering their second week of flowering, I can post a picture tommorrow of the whole plant.

so, I always thought that yellowing on the plants was a problem of having too much N. But I'm not sure what leaves the yellowing is on, so maybe it's some other nute issue.

If the plants are still growing strong though, maybe it's okay to just wait it out and hope for the best.

or you can try flushing things out and reintroducing the nutes to make sure there aren't too many nutes clogging up the plants and preventing the nice and yummy green color you want.

the lighting doesn't really sound like an issue to me, but the nutes sound like they might be.

did you follow all of the instructions on the Advanced Nutrients bottles or did you shift things up? I know I tend to go a little less strong in the beginning to make sure I'm not ODing my plants. But that might be something that only works for me...
