To flush or not to flush..? Nutrient burn?

the plants born back in the day

those are what they are at this point

lets focus on the newest plants

the claw at the top
I say a good guess is you've over fertilized, not real bad

those a big pots and the plants young
if the soil is worth anything you shouldn't have needed to add fert for a good while

that little bit of yellow on the starter leaf....ignore that lol
a wee bit of yellowing at the very bottom leaf or 2 is nothing

theyre very green, notice how some of the fan leaves look slightly cupping downward
looks like too much N

it doesn't look severe enough to need any major flush
id say only feed with plain water for the next week to ten days min

top dress with 1/4 tsp Epsom salt in about 4 days

in my opinion
personally I wouldn't top/pinch an auto!!!!
bend it and tie the tops but don't top it
your on a pre set time table and you don't have time for stunting even for a few days

are you mixing the fertilizer the way I suggested?
whats the EC/PPM
lets make sure your not using too much calmag.... the extra N in the calmag might be the culprit

when you do go back to watering with nutrient solution keep the EC low at maybe EC0.9 or ppm 650
keep it low until they look hungry for N before you raise it

I haven't ordered the products you've suggested yet. I've been using jungle juice three part from AN because that's what I've had and want to finish with it before spending more cash. Also Calimagic. I'll just keep giving it only water for now, but what does the Epson Salt do?

I figured you are still on the jungle juice/calmag

Epsom salt is magnesium sulfate

provides magnesium and sulfur to your plants

its a better source of magnesium than liquid calmag which is more calcium than magnesium along with some N and iron

calmag should be thought of primarily as a calcium product

your plants have plenty of N so your a little heavy on the base nutes

but I do see a tiny sign of magnesium def peaking in slightly...1/4 tsp should remedy it (1/2 tsp max)

that's why I asked if you where mixing the nutes the way I recommended.... along with the Epsom salt I mentioned way back in the beginning
if your adding calmag your getting your calcium but you could still be on the low end of your magnesium needs without the Epsom salt

your base fertilizer (jungle juice) is likely light on magnesium like most brands are

when you begin to water with nutes again ..add 1/4 tsp of Epsom salt to the solution every time you fertilize

don't use the over drive

the mix I gave you has what you need

adding over drive will throw it out of balance

spray
aminos are nice to use in veg only
kelp you can use anytime but not to frequently 1x week or every other week

molasses is for soil only
are you in soil? I forget

nothing

its just a fertilizer like any other

except its likely very high in P and very low in N

it could be used possibly to boost P but we would need to work it out
and you really don't need it

just adding it without knowing how it changes the math is trouble

you might be able to switch to only it for last last 2 weeks
I cant remember the numbers on the bottle

what are the 3 npk numbers on the bottle

it might look like this

3-8-7

or something
