Will do, thanks!Magnesium deficiency. Add 1 tablespoon of epsom salt per gallon of water the next time you feed her.
I hear you, and that is what I want to think because it would be a simple fix. However, my experience is telling me otherwise and that there is no deficiency but rather an environmental cause that would make this one behave differently.Not to muddy the water, but that looks like spotting from Calcium deficiency to me.
I have not done slurry, but i did check ec of runoff today out of curiosity, i havent done that in years. it was only .6, so that seemed fine. i feed .7-1ec, but usually leaning on low end.With agree with the K, did you take a slurry test yet?
I would keep the PK booster for very late flower if at all, that could possibly be related to the issue?
what npk do you feedI feed the same balanced NPK ratio the whole way through, I only adjust the PPM. I don't believe in PK boosters and I definitely wouldn't use them or a bloom feed that early in bloom, plants yellow too soon when you drop the nitrogen too quick, good luck!
Honestly imo it matters more if it's a balanced ratio; I sometimes use a 20-20-20 in bloom, but right now I'm using it in veg, and I'm using Master Blend in bloom; it's more about having an optimally balanced NPK ratio, and adjusting the PPMwhat npk do you feed
Wasn't going to say anything, till I noticed a few really thin fan leaf's pop out here and there in the pic. Still taking awhile for it to sink in, with me being hardheaded and all, that every issue isn't cal/mag or deficiency. But that's me!right at lights out. gave a .2ec foliar of grow (7-9-5) 10 minutes prior.
@Hidd3nGr0w i saw your post as im writing this, and these pics at link below do look identical to mine.
i'll flush em with ph water tomorrow
Phosphorus Excess in Cannabis Plants, Get it Fixed, Quick! - Percys Grow Room
Phosphorus excess in cannabis plants is a rare problem. Do you have phosphorus excess in your plants? Find out here and get it fixed!percysgrowroom.com
Doesn't this look like a P excess instead of some kind of def?
Or is that what you were getting at recommending the balanced nutes @Beachwalker and @Dirtbag?
A P excess can cause Ca and K deficiencies. When you have a lot of phosphorus and calcium together, it create Calcium Phosphate, which is a mineral that isn't useful to plants. The two chemicals, P and Ca, can combine together if in excess and cause deficiencies for both when they get locked up in the mineral called Apatite.Doesn't this look like a P excess instead of some kind of def?
