I have a quick question about (what I think) is a nutrient problem and would really appreciate some help or at least a confirmation.
Please see the pics. Is this a magnesium deficiency? I've done a ton of reading/research and think it might be that, possibly in addition to a K and/or Ca deficiency as well. I've just been using regular tap water so I wouldn't be surprised if I had some salt buildup and nute lockout.
Some info:
- mostly coco fiber soilless mix
- gave them a good flush 2 days ago; pH runoff measured just before the flush was 6.2-ish (water used when feeding always reads 6.2-6.4)
- was using bloom nutes that were a little low in the ratios (1.5-4.5-3), but just picked up some Pura Vida Organic Bloom (2-6-6)
If so, should I foliar feed with diluted epsom salts (they're flowering day 16)? Would a little shot of H2O2 help at all (the roots)? Should I give them another good flush before I start using any more nutes?
Thanks!!!
