I use biobizz(lightmix) and for feeding biobizz tripack + bioheaven + algamic.Temp is 21-26C when ligts on and 16-18C when off. RH is around 40%. In week 5 to 6 leafs started getting discolorated and having some patches of burn on them that i assume thats its not a fert overdose cause i was very moderate with the feedings.The story goes as follows.I firstly watered too much the sprouted seeds when i put them in the soil then i waited for a month to dry out and i stated feeding them once a week with biobizz starting with 0.5 lts upscaling to 1 lt till now(week7) most of the times i only watered them once a week and let the soil dry a lot causing a bit of droopiness but thats all.After week 5 things started getting worse with the leaves turning yellow from tthe bottom to the top .so in the middle of week 6 i decided to test the soil pH which turned out to range between 5.3 to 5.7 that led me to believe that a nutrient lock out is going on considering things getting worse .Now(week7) im yet in search on how to raise soil pH and why this happened and if thats the root of the problem .The other thing that im thinking is if the tap water im using that has chlorine killed the beneficial bacteria and turned the medium into "dead soil" so it cant manage the ph at itself but even if that happened why pH is so low (below 6) when at the same time the solution im feeding them stands at 6-6.2? tap water pH without and biobizz ferts has around 7.2 pH! Thank you for instance.Ill attach some photos of their recent look(week7).the last photos are from november 17 so u can compare.
