Progressive rust/yellow few weeks into flower

[i love herb]

its not that late... in my exp its too early to start dropping/yellowing


they havent even started their weight increase yet, still 3 weeks to go


think i should give maybe 2-3 ml of grow along with 10ml of bloom and 2ml hydroplex?

just in case you guys arent familiar with hydroplex, its the 4 week bloom enhancer

How far into flowering is the rhino? I was looking at the wrong pic I was looking at the pic you posted in the previous post


as for that much bloom I would not use that much... you will be using 12 ml of bloom.

How much water are you going to be using with all that 1 gallon?


pbp bloom has

2.5-2-5

hydroplex has 0.5–4–10

you are using 3.0-6-15 all together with just those 2

12 ml of that you will burn them.


10ml pbp bloom
10ml liquid karma
8ml sweet leaf
6ml hygrozyme
1-2ml cal mag


is a hell of a feeding for flowering. That's a lot of bloom....... I seen in your gallery your rhino had some burning or some lockout a bit....... but it went away....

why use all those nutrients? They do not need that much.

i did notice since its getting cool the temps are in the high 60's to low 70's with the light on... also the humidity was really high, 70% ish..

That's with the light ON? Yikes... do you have a lights-off low reading?
I strongly suspect that your plants are having trouble uptaking nutrients for reasons involving too-cold temps combined wiht high humidity... the plants are transpiring at a much slower rate. Do they seem to be using water slower as well?
I'd hit them with a foliar of 1/2teaspoon epsom salts dissolved in one gallon of lukewarm water to bypass the roots and deliver the Mg they need.
Cold, wet soils are hard to deal with. I've gotten in the habit of cranking up my perlite:compost ratio when temps are low so that there's always oxygen in the root zone. Let your soil dry out pretty well between waterings, and add a small heater on a thermostat to come on any time your temps drop below 65'F.

wow... ok... tell me what i should do then?

good plan, they are prolly dry tonight, ill hit with with some epsom salt and still maintain my 2-3ml of cal mag


also ill def be adding more perlite to my next grows and transplants.

the low temp last night prolly got down 65 ish >.< no way to know really at the moment... maybe even colder


luckily my flowering room with the hps is a steady 75 or so with the lights on... the cab is so low because its t5's

 

[MynameStitch]

dood that is cold, for right now I would not use no more than 1 tsp of each pbp bloom and the hydroplex..... you need to get them temps up...... like stinky said they are transpiring slower.

I would get a heater in there when the lights are off... you want to stay around 70... but if you are trying to bring out colors in flowering plants your temps would do it... but you have a decreased yield slightly.

 

[i love herb]

my flowering room has good temps!!!!



its the cab thats in another part of the basement that is low temps because the lights are T5 flouros and not a HID

 

[MynameStitch]

rgr that, was confused, thanks for explaining it to me. Now lets see how they do

Big update


The yellowing girls (Church and White Rhino) were fed

2ml pbp grow
2ml pbp bloom
2ml hydroplex
5ml hygrozyme
8ml liquid karma
5ml sweet leaf
2ml cal mag

ph'd RO water


Hope that helps the yellowing or at least give them some nitrogen back they depleted with the flush.


Church:




White Rhino:






White Rhino Left Church Right:




The Purple Kush which was flushed and fed immediately its looking a lot better than the other two. She was fed:

4ml pbp bloom
2ml hydroplex
5ml hygrozyme
8ml liquid karma
5ml sweet leaf
2ml cal mag

ph'd RO water

Purple Kush:









Decided to add a confirmed female Femaleseeds Grapefruit x Nevillas Haze to the flower room, heres the root ball





She went into a 5 gal bag and shes been lst'd as shes very sativa dom

 

[i love herb]

Few pics of my flower room if you guys were curious

Temp 73 with 600 on all day
Temp was around 75 with the 400 on today for the grapefruit
humidty 43%

 

[MynameStitch]

me is taking a seat up for this grow... count me in I am along for the ride

hopefully those new doses will make a difference..... without the hydrozyme you would not be able to use no where near the amount of food you were using

 

[Guest]

I just read the thread....

I use pretty much the same stuff.....

PBP lk and now and then cal mag....

From your first post I think what was doing the damage was too much pbp....

I think you should rethink your products a bit and use the minimal products then add them back slowly in the future....

You can grow beautiful plants with Liguid karma.... pure blend...and calmag....

If you use dolomite you may not even need calmag..... calcium and magnesium....

What I do is pretty simple.....

for small plants.....

10 pbp and 5 lk....

mid.... 15 and 10

And for a couple feedings just before the flush.....


20 and 15......

30 and you will burn them unless they are big plants.....

It looks like you have swung to underfeeding them......

For your plants 10 of pbp would be the least I might use and expect them to be eating reasonably....

 

[i love herb]

ya i thought that much pbp would be really low... ill start low and work up.

most people that use pbp say 10 is a base and move to 15 at some point but almost never over 20.


do you not use any bloom enhancer like hydroplex?

 

[Guest]

OK .... I gave you the simple plan..... but not everything is so simple....

Im not sure if what you refer to as Sweet leaf is the botanicare product sweet but I use that as well.....

But then this complicates things a bit.....

Sweets major component is magnesium... It actually has way more magnesium than cal mag.... one reason I only keep cal mag around just in case......

Most flower enhancers are P and K.....

Botanicare has more K than almost any fert brand......

SO no.... unless you consider sweet as a bloom enhancer.....

You cant make the plants eat more P and K than they need......


One good thing about pbp is that there are many people who use it....

for good reason......

Clearly from your post you have used the search function.....

how you should feed imo should come from what you find following what others have done successfully.....

 

[i love herb]

sweet leaf is actually advanced nutrients

its a taste and aroma enhancer, essentially molasses

[Guest]

I read the ad....

it sort of turned my stomach..... some of the comments....

it borders on the unethical...

aside from that.....

They said its a great product.....

But.....

(I use the search a lot)

There is no buzz here on how great it is.....

Virtually nothing.....

The prices that AN charges ought to be illegal......

But until at least one person who can compare sweet and sweet leaf Im not buying..... and they better be raving....

 

[i love herb]

on another forum i visit they rave about it, i also have 2 friends that use it and love it.


im sure you have read about using blackstrap molasses, its essentially the same thing cept a bit better as it has other things in it.


its just carbs, for weight gain and for flavor/aroma

 

[i love herb]

you should upload some photos of your plants, would like to see how the look with your feeding plan

 

[i love herb]

The vegging plants are looking a lot better, their new growth is coming in very nicely. I selected the best 4 and also strains that i havent harvested yet to put in flower. I have 2 White Rhino and 1 Randy candy left in the veg cab

Added 3 Isis and 1 Grapefruit to flower room

i fed them and the remaining vegging plants:

6ml grow
6ml sweet
2ml cal mag
5ml hygrozyme
8ml karma



New growth looking healthy, finally getting them out of the humidity box. The veg box is 67 degrees and 67% humidity.









Here they are in their new home, i think they will like the 77 degrees and 40% humidity.







For those of you that are curious here is happy frog:

 

[MynameStitch]

Hey looking good herb Nice greenish!

Yes, it's always best to work your way up, that way you know how much the strain can take instead of just adding a big boles dose, when you do that you do not know how much they can take. Where when you add increments you know when to go back to how much they were able to have before you have issues.
