Lucas formula, ppms low?

I'm running what amounts to a rdwc, using the lucas formula under bloomspect leds. The ladies are taking off like gang busters with no noted deficiencies. Probably my best grow yet, using 5ml/g of floranova to top off the reservoir with about 2g once a week. But... my ppms are a bit low at 500 heading into the third week of flower.

I've never used a tds meter before so I'm not sure if i should up my nutrients or stay the course since the ladies seem to be doing so well.

Any advice appreciated.

If the plants are going gang busters then what you're doing so far is working. You could probably bump the nutes up a tad for a couple weeks and then taper down the strength. But If things are going good why change anything?

Those look really good! Like ^xtsho said, you 'could' bring the ppms up, but why? If it ain't broke...
I'd finish this run and do the same thing next run but at this point pump it up and see if it even make s a diff. Thats where a pen is good. You can walk your nutes into the range you want them, not a chart.
I myself like to play mad professor and measure, and weight, experiment.

Just get a baseline so you know if what you're adding is even making a difference or are you just flushing money thru your plant. Good luck

Yeah they are really doing well. I have 8 or so grows under my belt, but this is my first hydro run. Still learning alot.

Thanks for the advice much appreciated.

I too am using floranova bloom Lucas formula.

I slowly ramped up the nutes as I'm growing in FFOF and it's pretty hot as is. 2ml/g then 5ml/g , next feed will be 8ml/g

Day 9 flower for me, 5ml/g was last feeding. Next will be 8ml/g

It's been easy for a first timer like myself. Still long way to go but so far so good.

If they are healthy leave them is my opinion. I've used that formula before in hydro and it can work great. I recently switched back to a nutrient called Envy that I used a few years ago. I highly recommend it to people. Envy is awesome quality, low priced, simple, and extremely effective.

I'm a firm believer in balanced feeding all through the plants life instead of trying to slam it with nutrients in flower. My plants grow nice and green and healthy right up to the last couple weeks and then typically get a gentle fade. I feed till the day I harvest and then a slow dry over about 7-10 days.

People rave about my weed and they never know I grew it so I don't think they are just being nice.

Do you have a link for envy thundercat?

I wouldn't mind having a look

Non precipitating, stays nice and stable. Doesn't leave residue in the resivoir or tray, and it's completely clear so it won't discolor roots either.

Thanks will have a look.
