Soil type and what kind of nutes you are using. pH of those nutes.
Its most definitely a deficiency, but I need to know exactly what they were getting prior to it showing up. This looks like a Molybdenum deficiency with a bit of phosphorus def. thrown in. Since the two minerals are connected and its not unusual for Molybdenum to take on characteristics of other deficiencies as well.
Definitely not over watered. The pots are light each time I water. Im using coco in a smart pot so they evaporate quickly. I water when the pots become very light, which is about every third day.
Soil is botanicare ready gro, (basically a coco, perilite, soil mix) nutes are cutting edge solutions with a little bud candy thrown in. Ph is 5.9 to 6.1. PPM around 900.
Try increasing the phosphorus and micro content in your nute solution. If the red continues to spread to the younger leaves its being locked out by pH.
i would definitely supplement with cal/mag(for deficiency), humic/fulvic acid(to enable plants to uptake more nutes without burning) and dripclean/clearex(to clear out any salts in the medium). Along with your full nute lineup, you should be good to go.
Also try to water until there is some drainage for a while to also help with saltbuildup.
Harinama are you suggesting that a higher than 900 ppm would be beneficial to my plants if they had humic acid in them? Or are you saying that I should put humic acid in to help my plants with the fertilizer that is already in them?
I didn't think so and thats why I thought it probably was due to lack of phosphorus and sulfur. The pH recommendation was only if the problem continued to get worse, than I would take a second look at my runoff for abnormal pH. Budgrowth is always slowed when deficiencies pop their ugly head. The plant must take from somewhere else if it cannot obtain what it needs to keep its most basic functions running.
Thanks, just looked at cutting edge solutions and I think I figured out my problem. The additives I was only using as a foliar spary (which ended a couple weeks ago, then the problem started.) I didnt know I needed to add it to the reservoir. I think that after I add these and water with them it should take care of my deficiencies, and at least the next crop will be healthier.
ok, first of all, you're in soil, or you're in coco, not both (unless you mixed them). your first post says soil, a couple post later says coco. SO, if you are indeed in coco, then i would drop your pH to 5.6-5.8 and def. not go above 6. (if you are in soil, 6.3 is more like it) and my first culprit in coco would be to add cal/mag (i use botanicare at 6ml/gal), but more importantly, drop your pH. a flush (water with plain water pH'd to 5.6-5.8, or with clearex or the like) would also be nice to start. then continue on, maybe drop your nute ppm in half for a watering or two, just to make sure your not burning.
