What should my rez feed PPM be at day 64??
Enzyme product at manufacturers recommendation.
Grow 2. ml per g
micro 7.5 ml per g
bloom 12 ml per g
let rez bubble for a few minutes test ppm
should be 1300 or lower
If it is low ( it should be) bring it up slowly so that your ppm is between 1000-1150 No higher.
test ph-
adjust as necessary to achieve roughly 5.9- 6
Here a link to the GH feeding schedules.

I adjusted it down to suit your problems and slowly brought you up to almost full strength.
In the future, if you continue to use GH, you will want to start off at about 1/4 strength of their recommendations and over the veg period slowly increase the feed strength so that when you get to the bloom stage, if the plant can tolerate it, you will be just about or at full strength.
Keep an eye on the EC, when you notice the tips burn, note the EC. That will help you keep the plant from burning in the future.
Whatever the case, do about 3 or 4 grows just sticking to the basics. Don't add a bunch of crap or fool around with trying to "push them". Just learn what giving them the basics will do. It doesn't cost as much and You will be pretty damned impressed with yourself and your plants and then you will have some basis of experience to test other techniques or nutrient lines.
