Wurlz F1 Automatic beginner Grow

*Tapwater: 21,3 °dh, 7.7 PH, μS/cm 700 Ph down to 6.6 50% light 400-500 ppfd

*Tapwater: 21,3 °dh, 7.7 Ph, μS/cm 700 Osmosis 23°, Ph 7 μS/cm 500 switching to osmose only, adding additional Cal + Mag planned keeping light at 50% (400-500 ppfd), i fear more light will worsen the deficiency until i buy calmag (biobizz calmag 1ml = 33mg Calcium, 11mg Magnesium) 0.5 m distance i suspect Cal+mag def due to lack of transpiration caused by LED, too much kali, cal mag imbalance or everything at once Lumatek would suggest 100% and 0,5 m distance at this point

preventive SF nematodes & predatory mites added (Amblyseius cucumeris) looks like all 3 powered through my butched watering at the beginning

Reducing Cal-Mag from 1 to 0,3 m,l/l probably wasnt the brightest move After some research, i'm not sure if lack of calmag or lockout due Ph dipping below 6 i'll test the runoff asap. 13.02 IN: 2l -Ph: 6,5 - μS/cm: 540 OUT: ca 200ml -Ph: 5 *possible, lockout? - μS/cm: 630 15.02 Soil Ph at root lvl: 5,5 Lockout confirmed, still don't know why got myself new calibration fluid & Ph-meter, double checking my old Ph-pen and cal. fluids asap *old Pen + old fluid vs new pen + new fluid old pen: 0.4 + Ph *old pen + new fluid vs new pen + new fluid old pen 0.1 - Ph This probably contributed but it's not too far off* I noticed some mineral residues from evaporating, my filter isnt nearly as good as i need him to be. Hard water is a curse, i'll test for Ca, Mg and K contents soon and dilute it with rainwater if possible

Changes: -ventilation timer from 18h to 24h, this'll fix my nighly humidity spike -new feeding schedule 1/2 of the previous -aquarium omsosis filtration ordered -isolated plant(1) with hight deficiencies with weaker light until she bounces back bless all people who pass down knowlege to absolute idiots like me hopefully my water problems will be gone Tap μS/cm : 760 Ph: 7,6 Osmosis μS/cm : 80 - 50 Ph: 6,9 - 7 JBL water testkit after double checking Ca: 100 mg/l Mg: 80 mg/l first time i converted the drops wrong for 5ml instead of 10ml and got some 200mg/l Mg :^) it's probably fine to use but i'll give RO water a try

25.02 I'm splitting up the weekly feeding into two (Nope, that was a bit to less, no longer doing that) 1/2 Nutes + Cal mag μS/cm: 300 Ph: 7,2 27 + 28.02 Osmosis water + 1ml/l calmag 01.03 1/2 Nutes Ph: 6,8 μS/cm: 260 i flushed P2 + 3 cause of high EC and low ph in P3 P3 μS/cm 850 to 660 p2 μS/cm 1600 to 790 Ph: 4,8 to 5,6 at this point, i can't wait for this grow to finish... i want a clean slate and start over, different soil + proper filtration and new schedule. Since Grow 1 + 2 went swimmingly it was hard to trace it back to my feeding habit. Learning through mistakes is as much fun as it is annoying

03.03: EC Osmosis = 0,06 + Calmag 3ml/l = 0,36 + Nutes = 0,67 Ph 6,8 runoff was good 06.03 EC Osmosis = 0,06 +Calmag 3ml/l 0,36 Ph down to 6,8 Runoff P2) EC: 0,45 Ph: 5,4 P3) EC: 0,46 Ph: 5,4 P1 didnt need watering 07.03 EC Osmosis = 0,06 +Calmag 3ml/l 0,36 Ph down to 6,6 Runoff P1) EC 0,44
