Recipes are meant to be tinkered with because plants and setups are not created equally.. (How many watts/sqft are you using??) But as UB always says, less is often more.. Don't feed your plants just because it doesn't seem to kill them, either keep levels where they are, or even lower them for safety until the plants shows the onset signs of need, and you have ruled out the possibility of pH trouble, or lockout, because adding more fertilizer when they are the cause can make things much worse..
In general its better to under do things than over do them.. Plants with actual deficiency onset will blast into action the moment they receive food.. Plants that are over-fed have alot more work to do to get back to growing vigorously.. And its not even the leaf burns that are the real problem.. Its the root burns, and improper salt proportions that really reduce potential..
Lastly, plants will appear to thrive like mofos when they are overfed, but that will change quickly and drastically when reality catches up..
