Is this nute burn? I've looked at the pages showing defeciencies but this yellowing is coming from the center of leaves with green tips
Since I'm not doing hydroponics I've never checked the ph balance and wouldn't know what to look for if I did! What do you suggest?
OK, Thanks! I'll go visit my friendly neighborhood grow store tomorrow and see what they suggest for checking ph. Is 6.5 what I'm aiming for? I had some epsom salts here and did a foliar spray just a few minutes ago. I found a note that said 1/2 tsp. per 32 oz. water. Does that sound right to you? I haven't noticed any changes to the smaller leaves yet, but I know it's just a matter of time. How often should I do the epsom salt spray and for how long? Oh man, I want to save this crop!
