An EC of 1.6 in veg is a bit high to me. I would lower that down and confirm your nutrients has everything the plant is going to need. micro and macro. I'd also lower the PH by .5 down to 6.5-6.8 for soil grows. If you keep with heavy feeding the salt buildup in the medium will cause lockout issues in the coming weeks. Best Of Luck!

Lime works on the soil to raise its PH Sulphur works to lower the PH These are more long term options for soil. PH 1-2-3-4-5-6-7-8-9-10-11-12-13-14 1 acid 7 neutral 14 alkaline. I would be more likely to use a PH down product for this. Phosphoric acid is a great, nice buffer period as well. Some other PH down products use citric acid, and it does not last as long in the medium and the PH will rise again within 24-48 hrs. Also coffee grounds will tend to lower your PH vs raise it. To many coffee grounds can cause some issues. Good Luck!

Aluminum sulfate to acidity ph down. Dolomitic lime to alkaline ph up. Ph levels are just another spectrum, like all spectrums its better to enact change, although each strain/plant has a preferred ph, going to far off will cause lockout/sickness. On the flip side keeping the ph religiously static has its own set of less known problems. Minerals/Nutrients have varying preferences that effect uptake rates through the rootzones. Manganese for example hates Temps below 67 and uptake levels will drop. Trying to produce "purples" using temperature drops too early ar the wrong stage of development will destroy yields as is vital for flower formations. I have a small diagram on one of my diaries somewhere I will lookup and link when I'm home. Each nutrient has a preferred ph also. What nutrients uptake well at a ph of 5 is night and day from the levels at 7. The curves are drastic. Like all things in nature ... the seasons driven by eternal change. This is the secret of life. Provide your plants with any old range between 5 and 7 and stop ✋️ working about being perfect. I personally cycle between 5-7 uptown shake it all around. P.s go organic. Nature always knows best, There is a multi billion dollar industry that wants you to feed your plants cheeseburgers and pretend it's all cool. NPK

That big bloom is very low concentrate. I would use every other watering...build up the dosage of the big bloom over time, don't give it full strength right away. Once you see flowering I would switch to fox farms Tiger bloom...also starting a low dose and building tolerance over time. Happy growing!

That is a lovely looking plant. No need to scrog at all with just 1 plant it's mainly done to control height and make a canopy of bud. With just the 1 plant you'll get more out of it by training her upwards and if you want top. But even then, she looks so nice and healthy I think left alone for at least another 2 weeks then come back to it. Happy growing. Good luck.

I don't think it needs it. Your could skip and be fine. Maybe some LST to help get the light down in there if your worried. Good Luck!

to help pick out a previous answer -- most likely just senescence... pistils turn orange-ish and retract until they are little nubs or curl up small etc... As the plant nears end of life (senescence) it will go through some inevitable changes... and this can vary by plant a bit - e.g. canopy may turn a different color. pollination can have the same effect on pistils and slow bud development.. do you have any male or hermie plants in the room? yet to hear of immaculate conception in plants... usually, but not always, happens top-down (parts with potentially too much light/heat speeding process), so maybe look around for nanners but i wouldn't worry too much... should be doing that alreaady, anyway. It's only going to pick up and all over plant. It is one of 3 metrics you should use to determine harvest window -- trichome color, pistil color, bud density.
