Hey everyone, I’m new to this forum and new to growing and I’m wondering if you can help me identify an issue I’m having. There are small brown spots appearing on the older leaves. I’m using an aeroponic’s system for the time being and will be transferring to a RDWC in about a week. I’m currently using advanced nutrients organic and following their nutrient calculator to the T. Any and all advice is much appreciated!! Sent from my iPhone using Grasscity Forum
what are your ph levels id say it looks like magnesium deficiancy or manganese excess im not sure what the ph leveps are supposed to be for aeroponic but ive got a sheet for hydro but again ill look into it and you may want to do the same if its ph if its not its got to be the nuits lacking magnesium wich is common id recomend getting cal mag or something with magnesium wich ever you prefer and add accordingly. if its excess manganese then i would recomend finding a nuit with less of it as altering the ph may just lead to another def.
Thanks for the quick reply! I was adjusting the ph manually at first which was giving me drastic ph changes every day. I just hooked up an auto ph doser and I’m currently holding it at 6.3-6.5 Sent from my iPhone using Grasscity Forum
id proly go more with 5.7 or 5.8 and 6.3 for ph but again im running off hydro but assuming they have simular ph absorsion those would be your better numbers for maximum nuit absorbsion.
