continous lockouts?

week 5 of bloom,

approx 50% humidity,
getting 1/2 tsp Cha Ching,
heavy dose of cal-mg (with RO water)
1/4 tsp superthrive,
some silica, and some epsom salt
soil ph around 6.1

It keeps looking like I'm getting a phosphorus, potassium, calcium and magnesium deficiencies, but everything they're getting is full of those, which leads me to think it's some kind of lockout. usually the leaves turn yellow and die from the inside out (from the main stalk out) as opposed to from the bottom up, usually associated with ph problems. If anyone has any idea what might be causing this, I would be grateful to hear

Stop feeding them and start flushing. You can't keep expecting a different result when you keep doing the same thing. Good luck chuck.

I havr heard superthrive is not good fow flowering but no real knowledhe other than hearsay.

How do you know your soil ph? That's not something most people know, and not easy to measure accurately. Are you using one of those $5 probes from Home Depot?

What soil do you use? How well does it drain? How often do you water?

I've used a soil probe (around $20) from the hydro shop, and done pour-through tests, they come out about 6.1. I'm using sunshine advanced #4, and it's loaded with perlite, so it drains really fast. need to water twice-thrice a week

How did you do the pour-through test? Are you measuring runoff from feeding, or did you really do the 1-hour pour-through? (It makes a difference in interpreting the ph of the runoff.).

You said you're feeding 1/2 tsp Cha-Ching. No other nutrients? 9-50-10 (ratio 1-5.6-1.1) seems unbalanced. I noticed the product page says to feed every other watering. Do you do that?

If your soil ph is really ok, I'd suspect that ratio is the problem and I'd mix it with my veg nutes to get some more N and K in there.

my expierence cha ching and rest of salts in the foxfarm line kill soil health if not used in conjunction with some kind of root drench/mircrobe food. fox farm has some good options in the bushdocter line, kangaroots/sledgehammer/microbe brew is what ive been useing with salts. howver i go 1/4 strength. and never put my tds above 800-1000 during peak flower. ive seen that same thing over and over and nowadays i dont even use the cha ching at all and seems to have helped. i would flush and try something other than chaching. tiger bloom and big bloom are much more stable and give great results in flower if you like foxfarm.

Stop feeding. Flush then let the pot dry before resuming feed. Start at 1/4 strength nuts. Feed water water.

i would flush a bit..how much cal mag you using and how often...to much cal mag can lock out every thing...people use cal mag whem they only have a mag def and vice versa..plus youe adding epsom saLTS ON TOP OF THE CAL MAG...

I would also get a good flower nute ..something like FloraNova bloom...but stop feeding now and flush....also start using some kelp in your watering...it has it all in it as far as minerals and other bennies..cha ching is heavy in the salts and causes PH swing in soils...even the dyna grow cloom is better than ching...I am not a fan of FF...did a grow a few years back with it..got alot free from a trade show so decided to try it..worse stuff on the market...

So flush..flush...do some kelp..and use a better bloom nute..dont let the big numbers of the formula make you think your going to get massive buds..you just may end up in problems...Keep it Simple...
