Hey Tony, nice to meet you
First things first. We need some info. Pretty much every nute company has charts. Most are just a blanket cannabis chart, which work for photos. Typically photos can be ran at a higher ppm, so high that auto's can't handle it.
Do you have a ppm/ec meter? Starting off lower and working your way up is the right way to go about it as you have been.
It is more specific or easier with a meter, especially for others to diagnose your issues. If say I have never ran you line of nutes, I just can't say with certainty that you are over/under fertigating.
If you can provide some more info it would certainly help.
-Ppms of nute solutions
-Medium (soil,coco,hydro) coco needs nutes every feed, soil is usually just water until the nutrients are used up around 3 to 4 weeks then a feed, water, water, repeat cycle.
-Are you ph' ing you feed? Soil vs coco or hydro need different ph levels. This can cause ph lockout which will look like deficiencies.
-pictures are worth a 1,000 words. Give us some whole plant pictures under natural daylight. Turn your grow light off for the pictures and use your flash. Also include close ups of affected leaves with issues.
What is your water source? If using well water it can have an extremely high ppm. If you are on city water you can usually get a water report online that breaks down what is in your water. This can be a total difference maker in your grow. Must need info.
Good luck and try to get as much of this information in here so we can figure out what's wrong.
Good luck growing!
