Female Seeds C99 - feeding question

[yesman]

Hi all,

I'm running a stealth grow with a single plant in flower and a couple clones vegging of FMS C99. Love this strain's low/different odor for stealth and its deliciousness. This is my second run, last one being several years ago.

Here's my question to anyone who's familiar with this strain:

I've been feeding her at 1.0 ec but it seems like around the start of week 3 in 12/12 the plant started showing signs of overfeeding via burnt tips. So, I backed it down to .8 and now it's at .7 ec. But, you can see a little burning that had already occurred.

Day 25:



It's a pretty short plant, 29cm. Has anyone run into any similar experience with feeding FMS C99 in flower?

Went to feed her just now and saw this:




That looks like more burning happening on the sides, right? I'm backing down to .5 EC now. So strange...

Try to flush her and resume feeding after with ec a bit lower than 1.

Ahhh...this could be caused by nute/salt build up? Flush with straight water? In a 1 gal. pot, how much would be enough for a good flush?

Cant say, i never flush because i grow organic.
There should be plenty of info on proper flushing around the internet.
