Plant are not eating at all

[Kingkongbud]

isolate u mean move them to another buckets ?

If you had waited too long to water irreparable damage will have happened bottom up

 

[rkymtnman]

if you can. then you can baby the yellow ones back to health and not affect the healthy ones.

 

[Kingkongbud]

Don't overthink a few bottom yellow leaves. If they are over 50 percent yellow cut them only a few every few days. I just did mine and the further yellowing slowed

 

[kratosxxl]

This is what it looks like from top.
so when i first dropped ppm to 900 some leaves started to turn green
Also can it be light burn ? this plant is right in the middle of my HLG550 Rspec and thats the highest PAR lights are 17 inches from canopy

 

[kratosxxl]

can u see how small leave with tricomes are green and fan leaves are yelloish ?

problem 1

problem 2

i think you nute burned and have now locked out the yellowing ones. could also be rot so check for that too.

flush for 24 hrs with plain water. start back on NovaBloom only at about 300ppms and slowly increase the feed.

and if u flush its just water no nutes with adjusted ph right ?

yep, that's normal. the plant is trying to protect itself. it will sacrifice the fan leaves first before the bud + sugar leaves.

but look at all the leaf tips of that plants. see how they are brown almost whitish? that's nute burn. which leads to nute lockout.

i used to pH first but i found that it didn't matter. the pH will be outta whack in a short time anyways without nutes.

can you isolate the bad plants? if not, this is your only option if you want to save them. they will take a bit to recover and your yield will suffer but hopefully you can make it to harvest.

yeah i cant really isolate them but ill try to save them at least , this is my first grow u need learn somehow

 

[rkymtnman]

even the green ones look like they have tip burn too. so dropping your ppm's will help them too. they were jsut bigger and could handle the stronger nutes longer than the smaller plants.

i understand totally. you gotta break some eggs to make a great omelette.

my advice for next time: only the floranova. don't go over 1.2EC or about 600ppms and see how they do.

that makes lot of sense not all 7 were the same size , 3 just couldnt keep up with the rest

i was actually thinking to switch to 3 part GH after this , Flora Nova is too thick and its difficult to mix . i use 2300Ghp wave maker to mix nutes and even after that there is some stuff on the bottom of bucket.

bingo! the secret to rdwc is to find the bare minimum ppm/EC that makes all plants happy. it takes awhile to recognize that and figure out what that ppm is.

SO but i still like to use koolbloom and fl plus so just i cut recommended to half ? to stay within range ? or go super low on main nutes and do full dose the rest ?

it is like molasses, isnt' it? but it is good stuff.

3 part GH are great too. if you want to get cheap and good, get a bag of MaxiBloom. GH are all based on Lucas formula which is why they all work great.

since everything is closed due to COVID i cant get MaxiBloom cuz shipping is too much

you can if you want. i wouldn't. i've done plenty of harvests with just floranova. all you need. it's the perfect NPK ratio.

Also the most confusing part is that lucas formula is 8ml floranova per gall that by itself is about 1100 PPM wont that burn the trees ?

yes, good point. it's really more about the NPK ratio than the amount. i only got up to 4 to 5mL before i got tip burn. same with lucas with micro/bloom: 8/16 was way too strong. but 4/8 or 5/10 worked fine for me.

i think with the 2mL per gallon, you should be somewhere in the 300 range. if it's too strong, add more water to drop it down.

@rkymtnman one more thing
So i have 2 Bluelab meter 1 handheld , 1 stationary
here is strange part
hand shows
PPM 590
PH 6.2
where stat
PPM 560
PH 5.8

can all this be cuz of wrong ph readings ?
