redlightspecial Posted June 11, 2020 Report Share Posted June 11, 2020 So many things that it could be is overwhelming & I’m left baffled.could bePh. (Fixed) past 24/48hrFeed/under fedOverwater/underDeficienciesLighting/distanceDisease/petsRoot rot pot bond(forcing probe 4 ph reading is tough penetrating roots)? AM I ROOT BOND? Shouldn’t be 5gal smart pots successful few seasons ago.At least this time no signs spider mites just a few springtails, which yellow sticky pads capture most.Swapped out Viparspectra v600 for a sp1000 and they were loving it, 18/6 now at 19” or 47cm between light and top of plantsThere under sp1000 & were thriving prior to this problemMy ph was high in spots peaking past 8 and slowly drop to high 7’s, however with Sulphur and liquid Sulphur I’ve managed to correct it to 6.8-7.5 in soil. Added nitrogen to soil & it was getting ½ nutes, hit with couple spoons cal/mag, Epsom salts yet still problems persist! Yet still has a drooping all over like overwatering but yellow started on lower fan and now is lining entire plant. Plant looks hungry but drooping leafs & at times crawling!!!Co2 bag with goid ventilation, 24.5c @ 50%RH at canopy and21/22c and 60%RH at soil.Co2 bag is on ground with extraction fan above lightsIntake fan bring fresh air in at ground level. Going to start removing co2 bag at lights out.OverwateringSo I stopped and watered every 2nd day but plant was still yellowing, drooping & crawling.So I’m now flushed with natural 7 ph water from tap & spring waterAfter flush I ph my run off, dipped just a needles thickness towards 6, so I’m guessing it’s like 6.8 so run off from flush was fine, I’ll give it 3 days to dry out somewhatAnd I’m thinking maybe another flush before starting back on gogo juice!!!Do I reflush & hope she’s takes to feeding or cut loses and start again, idk.Thoughts advice plz!!!Pics are 10-12 days apartClearly you can see difference!Special kush back leftFront right unknown strain, with some heat lamp burn, cause it’s directly under heat lamp. Only use when temp get really cold & it’s on 30 mins on/off timer.Using same smart pots used lasttime. Temps got cold few night back, temps haven’t fallen below 15-16 at lights out.First thoughts, plan of attack was(N) given nitrogen to topsoilPh (fixed over past 24/48hrs)Overwatering addressedTrace elements & cal/magFlushed neutral ph waterTested run off metre barely moved off 7 maybe 6.8Now what should I flush again?awaiting digital ph pen & Ec reader Incase mines dodgy.And I’ll lower light abit 19” to 14-15” maybe?I just don’t know anymore...Posted from the OZ Stoners mobile app Quote Link to comment Share on other sites More sharing options...
