Day 39: No water today but she got quite the haircut, maybe the last before she starts flowering. Her pistols are all opening up.

The last 7 days, the humidity and soil temps have been down a little due to no light getting through to warm the soil and evaporate the moisture but it's all within the sweet spot.

and here's a few days worth sneakypeek

Day 40: No water today but mixed up a new 7L batch of nutes for the coming week and adjusted a couple of the pegs.
She is just recovering the bushy bush after her haircut yesterday

What's that? It looks professional and intelligent

What's that? It looks professional and intelligent

It's my raspberry Pi monitoring setup. Tutorial is in my sig below.

Day 41: She had around 3.5L today of pH 5.81/1050ppm with around 20% runoff at pH 6.12 / 1140 ppm.
Can keep a good bush down, she's bushy bushy again!

Read a couple of threads that suggested with LED there isn't a stretch so thinking it might not come which is good in that I have limited height, but bad in that there won't be long buds

Shes looking great mate couldn't tell she had a hair cut few days ago.
Also mate i donno if im doing it wrong but i thought if you feed with say 1000ppm then the run off should be lower as thats what she has eaten? As my runoff is always like 500+ lower ? Im confused haha

@Epicxr I don't think so....but I'm new to this. If you flush for example you should get the same out as you put in. Given that I didn't flush until last week for the first time (but also didn't water that much) there was a slight salt buildup which meant my runoff was higher than the feed. As I continue flushing, I expect it to be close to what I'm putting in, so my runoff was around 1450ppm and is now down to 1140ppm (last batch of nutes was 1180, this one is 1050ppm). My pH runoff is a little higher this time than last (5.82 vs 6.12) so I need to keep an eye on this as > 6.0 in coco means nutrient lockout might happen.

If your runoff is a lot lower, if may be that your coco is holding on to some of it?
