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

Delta-9Pyromaniac · Jan 30, 2017

I've seen this yellowing on the leaves and am worried I've done irreversible damage. Can someone diagnose or confirm that this is nutrient burn, and maybe help me figure out if she needs a flush. If not, help me fix this issue

. Any and all opinions are appreciated.

whats it growing in, under and with what nutrients?

She's a lowryder #2, under a 300 watt full spectrum led. She's in lambert organic potting mix, using three part jungle juice nutrients. 155tds way under. She's six weeks old

You need more cal-mag and nitrogen

Delta-9Pyromaniac · Jan 30, 2017

What does would you recommend?

im4satori · Jan 30, 2017

I took a look at the jungle juice 3 part nutes

its good, and easy to mix

I wasn't able to work out the calcium magnesium and iron ratios for you because I couldn't find the % amounts

I did check the npk numbers and figured out how I would recommend mixing it

if you give me pictures of the % amounts listed on the label for each of the 3 bottles I can work out your calcium and magnesium ratios

per gallon;
veg full strength
7.5 mls grow
5 mls micro
2.5 mls bloom

bloom full strength
2.5 mls grow
5 mls micro
10 mls bloom

youll also likely need calmag and Epsom salt but again I cant tell you how much until I get the info fro you

for a slightly stronger formula, mix it the same way only with slightly less water
for a slightly weaker formula mix it the same way only with slightly more water

im4satori · Jan 30, 2017

if I had to guess about the calcium and magnesium

most of the time the answer is
per gallon
5mls calmag
1/4 tsp Epsom salt

but its a guess

Very high chance its the LED causing the Calcium issue, get a camag suppliant and feed at the recommended dosage and as Calcium is very slow moving around the plant, to get a 'quick fix' foliar feed once only at the rate of 2 ml/L.

Not an over feeding issue, good advice already given. Good luck!

She's an auto. Does that matter?

doesn't change anything

OK, so more nutes, add Cal Mag. Got it! How do I show yall love and like stuff/response/profiles?

Delta-9Pyromaniac · Jan 31, 2017

I got the Cal mag today mixed it with the nutes as recommended on back of all the bottles then watered it half nute mix half PHd water to start it off. Measured 823 ppm full strength

Here's an update. Harvested day 71 at 22g dry weight.

im not sure if it was mentioned.. but when using any of those 3 part nute lines. make sure you put in the micro FIRST. and let it mix well. then add the other parts. and the cal mag and any other supplement unless you are using silica additive .. that should go in first. then the micro.. you will have lock out issue which will cause problems like the one you had... and its best to flush when things are not what they should be..and always check PH .. and flush that last week with fresh water.. enjoy the fruits of labor..

Thanks for the advise. I was told about adding micro first before I started but I appreciate the advise. Any advise on supplements? Do you use amino acids, vitamins, carb supplements? What's in overdrive? I've been doing some research and don't really know what is good and what's a waste of money. Any advise is greatly appreciated

i personally would never use AN..idk what media you are using..but if your trying to get the most out of your girls and a simple high quality nute line. ? try Elite,, they will even hook you up with a sample of everything they make.. plus a simple to use app. for each week... .. you cant beat free. look them up on facebook.. to be honest the cutting edge did catch up.. but elite root ignitor.. is bees knees these were 3 weeks old when i up potted..

Delta-9Pyromaniac · Apr 3, 2017

Hey thanks a lot, I'll look into it.
