You can fill out the nursery questionnaire (click the link in my signature) to get more accurate help from all of us! Just paste the form in a new post here, and answer the questions as best you can!

My first guess right off the bat is that unless its a very sativa dominant strain (which by the leaves, it doesn't look so) that 500ppm/1.0ec is probably a little too low right now

I'm mainly curious to if you ppm has been falling or rising on checks, and if your pH has been falling or rising

i *think* its the start of a Ca deficiency

also, is the floranova bloom a one part nutrient? thats the organic line right?

hashberry is mostly indica.ec steadily falls throughout the week, ph has been constant around 5.8 all week and is topped off with ro water daily.i do underfeed due to only having a 250 hps and fear overfeeding more than underfeeding, but i could be wrong.they grow crazy fast and lush, so i figure they were happy.floranova isn't organic.

In the first post you made, i got the assumption you let the pH drift from 5.5-6.1 which is good

If your pH is 5.8+, calcium can't be absorbed, it needs to be a bit lower than 5.8 for it to be absorbed.

I know it's only been 5.8 for a week, so thats not bad.

IMHO, underfeeding is always better than overfeeding, but i still think you could stand a res change, with maybe 650-700ppm, and see if the ppm still drops, and if it does slowly bump it up. I would think for an indica dominant strain at 3 weeks flower you could be at 800ppm or even higher, but of course take it slowly to see what she likes

what kind of water are you using (tap, ro, well, distilled?)

the ph does drift from week to week.this week it's been around 5.8.maybe it should drift day to day.i use ro water.i will take your input into consideration and possibly bump up the ec with next weeks feeding.

i think it would be much better to let the pH drift up over the course of a week.

i don't know about the floranova bloom, so i looked it up i saw its a one part nutrient and is indeed organic, but maybe its possible floranova bloom doesn't have adequate levels of calcium when used with RO (since RO doesnt have the calcium that tap water does) and would need to be supplemented with something like calmag+

does anyone know if thats true?

thanks, i'm going to closely monitor them and hopefully it doesn't worsen.
