Kongo, i think its the water here, i get the same look of my plants too looks like Mg def as far as i can gather like i said above i test and ajust my water and feed my plants but still get the limeie green look off them i m using Bio Bizz light mix this grow and last and im noticing it again im starting to think ive no green fingers at all lol. ive been watching my temps very closly and humidity plus like i said good seed ajust water foods and still encounter that liming of the leaves at around 4 too 5 weeks so im working on the idea that our water is truly unhealthy out of the tap... im covering so many things that im running out of excuses as to why i get the same problem ech time even changing strain s dont help. i dont think its over watering as i always alow my plants to dry out before i water of course depending on the temps /pot size and so on ah learning all the time i just gets to be a pain in the ass when time after time no matter what i do i get to a stage then my plant s just go limie in colour,, with time i'll nail it. Aldo like you said if i had a nice spot outside id prefer to grow in a green house with fresh air and more room to work with. theres always issiue's..........
