Seedsman Speed Auto Stealth Grow

Hi Everyone!! This is my first grow in this new stealth setup. I've done a few through out the years, never with any detailed notes. This time it's going to be ALL of the notes. For those interested I germinated 2 seeds, both cracked but I accidentally broke the tap root during some rearranging. Seed to Veg was about 3 weeks. Moved to Veg 1st day of week 4. Setup: SF-2000 manually adjusted to 120w. 12 Gal Storage Tote. 6 inch netpot. 4 inch carbon filter. 2 4inch airstones to airpump Grow Journal Notes: Week 01 Sunday Temps creep into 88*F but fans are cooling the plant indirectly. Plant appears healthy, and has shows continued growth. 3rd set of leaves aren't completely open yet but are starting to flatten and spread. Adjusted PH from 6.25 down to 5.9. Monday Plant has purple stalks PPM climbed to 280 and pH to 6.2. Added PH balanced water and let rest an hour, res now at 250 ppm and adjusted to PH 5.9. Tuesday By morning res was 255 ppm and 6.0 PH. Brought PH down to 5.8. New stem growth is green, plant appears healthy. Already purple stem are remaining purple and of the of the lower leaves appear faintly spotty. Wednesday Res 266 ppm 5.9 PH, no adjustments. Plant is drinking more water than nutes, thin roots just starting to poke from bottom of net pot. New growth still green and no purpling at all. Faintly spotted leaves showing fresh green growth at nodes. Started training, bent hole plant over to expose the two lower nodes. Should hopefully result in 5 tops. Thursday Nodes are showing increased growth. Accidentally broke off a leaf from top node. Res was 260ppm 5.98ph, plant is starting to feed on nutes. Adjusted ph to 5.8. More root growth present. Added Cal-Mag and Silica up to 280ppm 5.8ph. Friday More great growth from nodes seems like LST was started a little late as main node has already started grow nodes that may result in more colas than intended or is recommended for such a fast autoflower. Water at 281 ppm, adjusted ph from 5.99 to 5.78. Plant seems to be feeding on nutes and water at equal rate. Will try to maintain 250-300 ppm for now. Saturday Node growth is green, some lower leaves are still spotted. Will let the plant auto-prune leaves. Fed more Cal-Mag. Res is 320 ppm 5.8ph. More roots are spreading out of net pot. (I've since realized the issue was the PH was not suited for calcium uptake, eventually I start upping it to 6.2)
