Hey, so I see a few issues.
1stly you are showing signs of cal def and them generally been hungry. This isn't because the lack of nutrients its the how you are using them..big bud is only meant to be used for the 1st 2 wks. And bud candy carboload are very similar in design. There is slight differences but very similar..so drop 1 of them and after a few weeks give 1 a try after dropping the other. 2 shouldn't be used together.. start with a L or 2 of water and your plant will start eating again..drop those those and after your soil dries out some cal or calmag. I use cal powder and Epson salt or just 1 when needed. What you are using has mag in them. So you are short on cal.
Big bud should be done too. Its just to help the pre flower process and thats it pal.
Drop carboload and keep the bud candy and if you like after a few weeks switch to carboload. But really bud candy is the better one.
Keep a steady Ppm..Do your base nutrient mix before adding any bud candy as these are your bread and butter. Just with base nutrients u wanna be in the 5-700ppm range and then apply 1-2 of these, you can split up the different resins/and bud enhancers into 2 dif feeds during a grow week. And you can give a 250ppm (tap included with a cal/mag or just cal)
If you need anymore help feel free to DM me. I started my 1st grows with these.
Good luck
