Here are some pics of veg and flowering plants that I am have problems with. I just started with new nutes from Botanicare. I am using Pro Bloom,Pro Grow, Karma, Sweet, Cal mag. I was using fox farm nutes and just didn't like them. This is my first grow and I am not sure what I have done? I am using fox farm soil for all the plants. Let me know if you need more info to help solve the problem. Thanks

Yea I have a ac in the bloom box and I have ducting going to the veg box. The bloom stays and 75 to 76 with the light on and about 69-70 when off. The bottom box or the veg stays and 75-78 with lights on and at 70-72 when off.
 
Yeah dude, nute and light burn is what it looks like and you might even have a pest problem as well.
 
Just to get something going I flushed all of the plants that had some kind of problem. How long until I should go back at the nutes and stuff??
 
personally i think its a deficiency since it started at the bottom of the plants...heat stress would start on top huh?

this is true. Dude flush for the next week then start her back up on the botanicare flowering nutes. Did you flush when you switched nutes? If not, well either way flush and you should then either see improvement or then you will know exactly what the problem is. But i deff suggest you flush for a week as she doesnt look to far into flowering so it wont be a big deal. Hope all is the best peace brother. :joint:
 
Thanks guys for all your help. How much water should I flush in the next week and how many times. Should I wait until she is fully dry before I flush more? Thanks
 
It is said that to flush you run about 3x the gallon of your pot of water through the roots. Personally I have had successful results using far less. Just run enough straight water through it that a fair amount comes out of the holes in the bottom of the pot/into the tray. After doing this I would not water for several days (until soil is more dry than moist) and I wouldn't start the nutes again for a couple weeks. Give them straight water for a couple waterings before you go back on the nutes and if i were you I would back up the ratio of the nutes about 1/4 from what you were using just in case. My 2cents. Good luck

Good info thanks man. I hope I caught my mistake in time.
 
I was checked the ph of my water and it looks to be about 5.8-6.0. Would this have something to do with the promblem. I thought it needs to be more aroung 6.5-7.0 for soil?
 
It looks to me that you may have a PH issue.
Make sure you flush with water at between PH 6.5 to 7,
then add some nutes at 1/4 strength to start with, and slowly build up the nutes.:bigjoint:

You should be ok if you don't give any nutes for a while. The leaves that already got burn may end up dying after a while though so if they end up getting more than 50% brown/yellow you can just snip them and end up with more than you started with :)

5.8 is a bit low 6-7 is ideal it shouldnt take much tweaking to get where you want. Do you know what your soil pH is? What we want is to get the run off water from the bottom of the pot to be 6-7 pH and remain constant so it may take a couple waterings to get it where you want but once its there it will be easy to maintain.
 
Also if you are using tap water which I assume you are let it sit out a day or 2 before adding anything to it so we can get rid of the chlorine which I still think might have something to do with the brown spots.
