I used a soil tester (gasp) to test the soil. I took a sample from the worst looking plant about 3" down from the surface.

I started foiliar (sp?) feeding the affected plants tiger bloom last night, as I'm still thinking Ca, and the first ingredient in that fert is Ca based.

I don't understand, as only half my crop is affected (thank goodness) and they all came from the same soil. Now that I remember it though, the consistency wasn't all that uniform and I was in a hurry when planting, so that may be the problem. Next grow will be with fox farms soil since there is a local retailer that will have the potting soil in a month or so.

I'm off to the X-Games now, so they'll get a good 12 hours more to just sit and enjoy the fertilizer. It's already been 16 hours longer than I've ever let them go between waterings, so maybe I'm messing that up too...

Look for me on the TV!
herbaltivo Reviewed by herbaltivo on . yellowing tips, brown spots, Ca deficiency? Hi, first time grower, 6 plants, bagseeds, day 23 of veg. 2 of the plants have nasty looking yellow tips on the lower leaves. Pictures say more than words. I water, but have not as of yet fertilized. I just got my fox farms products today and will be using them tomorrow. Soil is too wet to water today. 2 175w MH, 6 or so 100w cfl's for lighting. Temp is always around 78-80. Low humidity <20%. Was thinking about putting a pot of water in there to evaporate off some moisture. Three of Rating: 5
