I'll be watching this grow ! I have this strain in my tent for my first ever grow !!
 
General Hydroponics Ph UP is a common Ph buffering solution. People usually buy the UP and DOWN together to cover anything they may need to do. :)

To this point, the grow has been terrific. It is my first ever grow as well. She was grown in a 50/50 mix of FFOF and Happy Frog. I havent had a single problem til now. She is a little more stretched than I wanted in between nodes but I was having a heat issue in my tent til I added exhaust and light ventilation. Another issue I ran into was growing in the attic and now it is getting warm up there. With the heat, I was only able to use my 600 watt HPS at 50%
Flowering nicely until I found this problem. Hopefully the doctor here can help me pull this one out

I will stop at the hydro store and pick some up. I read many times about this but I guess it didnt stick. I sure hope I havent ruined a great thing
 
In soil ya wanna have your nute solution at about 6.5 going in. What are you using for nutrients? If synthetic ph'ing is a must!!!!! With organics it maters less because the bacteria and mycros if doing there job will basically do it for you.
 
I am using Biobizz Try Pack. Feed grow nutes only twice at about 1/4 strength. Honestly, I think everything was fine until after the second veg feeding, if I am recalling quickly
 
I have A 600 WATT also and am using a 50/50 OF and HF too so we are running a similar set up ! i hope things turn out great for you !!
 
Definitely ph EVERY time you feed/water. I'd give her a nice healthy dose of bloom nutes. She'll thank you by fatting those buds up. Also I'd think she could take more than 1/4 strength. Once established autos can get pretty hungry.
 
I will ph next feed. Her flowers get bigger every day. I will watch her and get some ph up. I havent heard from anyone regarding the use of sledgehammer to flush or not to. I have it but have read conflicting reviews from growers

Question?????..........This seems to have started around the time I gave her first grow nutes....I waited a while because of the nutes in the soil. Since I havent ph'ed up with those two feedings ( one a week) does this scenario fit the low ph profile?

I've never used sledgehammer before myself as ph'd water work just fine to flush.

Seems to fit to me. With a low PH cal and mag don't get absorbed therefor the plant doesn't get what you put in. Ca, Mg, & P all get locked out below 6.5 in soil.
 
and I guess with soil at 6-6.5 and nutes at 5 - 5.5....I could be running a bit low Ph. I have a hard time checking ph of run off due to the type of pan underneath bucket. I may flush her and start again on the soil...
