Hey guys!

I do not have a PH meter. I had a buddy over not long ago and he read the ph of the water at 6.8. The ph of the typical nutes I put in at 5.5. I honestly don't know what the runoff is from the soil.

I only use a 250w HPS bulb in flowering and I keep the temp in there around 70-75 degrees.

Part of the problem could in fact be adding the big bud too soon. I started using it at around week 3 but only used it once a week.

I am using 3 gallon pots. The plants are humungous because I wanted to get good clones from them - I grew them from seed - so I had to extend the veg period. My blue russians are already near 4-5 feet tall into week 4 of flowering. It's insane how big they are getting, which is why I think being too close to the bulb is hurting them so I'm keeping them away from the bulb a bit. The bulb is about 2-1/2 feet from the tops of the bubblegums.

Here's a pic - the bubblegum is in the front so you can see the distance from the light it's at.

My initial thought was lockout because of PH issues but I'm not doing anything different than I've done in the past and I've gotten great results. The only difference is the addition of this light and the big bud (I used beastie blooms before but I'm using big bud this time on a suggestion)
