She seems to be responding well to LST. I started LST between week 2 and 3 this time and also added some Silica to reduce the chances of breaking a branch.
I did a bit more defoliation this week. Being in such a small area, I find it really helps.
I have the CO2 controller working and combining it with another grow controller project to control lights, fan and CO2 with logging and an HTTP server for changing settings.
So I noticed that some of the top leaves were curing at the edges. Checking runoff, EC was very high for this stage (almost 3.0), so I have since reduced inbound EC to ~800. Hoping it was salt buildup vs root issues.
I am still seeing leafs curling up and some brown spots.
I moved the light further away, as I was thinking the leaves curling was a heatstress issue and reduced temps in the tent to 22-24c.
I am having issues late in flower. Curling leaves at the top and some brown spots. Please see photos marked #1 and #2. Last week I let her dry out too much (coco), so runoff EC eas very high. Have been keeping runoff below 1.1EC
@ccore I think she's telling you it's time to back right off on the nutes & supplements etc and give more plain water feeds as she looks to be nearing maturity
maybe another 7 - 10 days so about the right time to begin to start removing excess salts etc Just my opinion Good luck with your Harvest 👍
Overall, I'm very happy with this grow. One thing I would have down differently is reducing nutrient EC a bit earlier. This strain was a very fast finisher.
