Welcome to the community Grow Sis! You’re in good hands with @Graysin! Constant checks on the res to maintain 5.8-60 will be a daily routine especially with a small res and at this stage I would be feeding around 500 PPMS 
Welcome to the community.
@OGIncognito Thank you! I have the ph down to 5.8 and will be checking it daily, my TDS is 108… hard water. Will that be a problem? Gave them a complete water change and trimmed those big bad tell-tale leaves off… My little ladies are looking happier already!
@kellydans Thanks for the welcome. I’m so happy to be here and have already learned so much in so little time. This community is amazing! 
That tap water TDS is great, they’ll need some base nutrients at around 500 PPMs and keep that 5.8-6.0
@OGIncognito Awesome! Thank you! 
I was concerned when I’ve seen others are much higher. Which “base nutrients” can you suggest?
Jacks 321 would be my suggestion. Easy and clean. My tap PH is similar to yours with a 7.1 PH. After mixing full strength jacks it comes out at 5.8 and 1000 PPMs. You will have to PH down lower dosages
Thank you! Im on it! 
Everyone else read your post… lol.
I had it in my basket and still shopping… went back to buy it and its now unavailable…
I’ll keep my eye out for them to replenish.
