Pineapple Chunk "Gifted"

This is my first real week of Vegetative Stage. All prior growth was for seedling and root growth, so I slowly ramped up light schedule etc., to promote a healthy root zone. Although it says week 2, I am counting as first week. I know I'm probably off my rocker, as I performed LST, HST, during the aforementioned stage and it was a little premature, but I am trying something new and wanted to be sure the plant and I were ready. SCROG, is my next adventure with this grow, so I am training plant and waiting for it to get to a point where I can apply the net, which should be in a couple weeks. Numbers for runoff are still elevated at this time. I contacted Apera and meters are fine. I performed a cleaning and calibration on both meters. Plant looks healthy and happy. 1.5 gallons RO water... IN PH 6.04 TDS 329 EC 463 OUT PH 6.17 TDS 4650 EC 6550 12/24/22 Watered with 2 gallons of RO, Cal/Mag and Manganese. Okay, so I removed training aids and now I intend to let her go for a week without any training etc. Maybe two weeks. I think I get ambitious and impatient, which leads me to rush my training methods, which places too much stress on the plant. So I am going to try to just let her grow and stretch for now. Then one more topping, a rest for another week, then start introducing her to the trellis net for Scrogging. My first run at this so be kind...lol. My runoff numbers are coming down and rightfully so. I have been watering without nutrients for awhile now. It is my belief that the soul is still hot and full of nutrients so no need to feed for now. Once the runoff water indicates healthy numbers I'll perform a flush with Sledgehammer, then start feeding again per FFs Feeding Schedule on the next watering. I just wonder if using Sledgehammer is necessary at that point in time, but my limited knowledge leads me to believe that it is. I think it best to remove any salts built up in soil. Please tell me differently if applicable. Temperature outside is 7 degrees, so my basement is now 69 degrees, and tent is averaging 73 degrees. I lowered light to 12 inches and held my hand over canopy to test for burn. All good at 12 inches. I did this and adjusted all fans with the purpose of raising tent temperature. But, it doesn't look like it helped much, as it only increased by 2 degrees. Usually I am fighting the heat...oh well. IN PH 6.10 TDS 335 EC 472 OUT PH 6.16 TDS 3760 EC 5310 12/26/22 Watered with 2 gallons RO with Cal/Mag and Manganese. Numbers are starting to reach desired levels as I water without nutrients. Again it is a hot young soil from FF so this is expected. I think I will use Sledgehammer in a week or so to remove any built up salts and then start regular FFs Feeding Schedule. IN PH 6.06 TDS 541 EC 764 OUT PH 6.25 TDS 2350 EC 3320 12/28/22 Watered with 2 gallons of RO, Cal/Mag and Manganese. My numbers below are good so another couple waterings and then I will start feeding. I am training plant with tie downs to ready her for the trellis net in a couple weeks. I topped her and took a few fan leaves off,, but nothing major. IN PH 6.13 TDS 404 EC 571 OUT PH 6.38 TDS 1630 EC 2300
