Fox farm flowering help

Hey what's up everybody!

i just started flowering 7 days ago and mixed the FF nutes on the low side of what the bottle called for.
tiger bloom and big bloom...PhD water, run off is 6.5?

The very tips are burnt a little bit within a few hours so I watered with PhDs water shortly after I noticed it.

kind of a 2 part issue here...any suggestions on what I can do to correct this,if I cut back the dose too much, won't that limit the other nutrients that are in it that aren't causing the burn?
#2...on the feeding chart it says to mix some Grow Big in with the others for 2 weeks!?
If they are burning now won't that fry them later when I add the GB?

Never mind! 420 magazine has an active forum with members who actually help!

For fox farm to be soluble the ph needs to be 5.8 when you mix it.

Don't follow the label to the T. With fox farms you have to be careful with how much you feed. Just have to learn the right amount for the plants. I don't even measure the nutes I feed, I just eyeball it up. Definitely don't recommend doing that until you get the hang of it.
