Autos in soil, starting to have problems

I am struggling with autos in soil mostly because I am not very good at understanding what the plants are telling me. I starting keeping track of the TDS hoping that would at least give me some repeatability if I ever get things right. So, growing 4 in Fox Farms happy frog with additional coco and perlite. My well water reads about 125TDS and I am in the beginning of week 4 using Fox Farms Grow fertilizer gradually getting up to a TDS of 430 right now.

So, does this look like too much or too little or some other deficiency?

Thanks for your help as always!

They look fine. Might be a little nutrient burn but not much if any. If it was a big problem you would definitely know.

hey doc thanks for your reply. Yes it got worse and revealed its hand, calcium deficiency. I started adding cal/mag and things were good for about 1.5 weeks and now dealing with phosphorus deficiency. I have been so worried about over feeding that I am starving them I guess. Good lessons to learn tho, cheers!

Something great to always have is seaweed either powdered or liquid then mix and spray leaves good and give drink every couple weeks.
