Why leaves are dieing? 4 and half week of flower.

[Heart Of The MJ]

I HAVE POSTED THIS THREAD BEFORE, BUT THAT WAS THREAD TO RATE MY GROW, NOW GUYS IM REALLY SCARED AND CANT FIND AND ANSWER WHY MY LEAVES ARE DROPPING, DO YOU HAVE ANY TIPS?

hello all, so here it is, my 6 different strains Green House Seeds Co. (White Rhino, Great White Shark, El Nino, Train Wreck, Lemon Skunk, Church) Plants there vegged for 1 month and 1 week (with 9-9-3 + minerals nutrients), and now are in 4 and a half week of flowering (Shultzh bloom nutrients). Temp is ~27, humidity ~50-60, but few days now 33, but it will reach 27 again tomorrow, im watering them 2 each days (first day pure water, second day with nutes). What you think, are bud are enough big? Should I water with nutes each watering? Any other tips? this my first grow, here are photos, I know quality is bad but cant use my camera now. By the way leaves are yellowing and some of them are dieng for some reasons. Is it very bad? Any tips why?

Looks like it could be nitrogen deficiency, if so thats normal in flower. Next time hit her with a little dose of N at beginning of flower.

Edit: after lookin at the pics again maybe Sulfur deficiency?

 

[Kikeritz]

I agree, it could be lack of nitrogen. Another idea is iron deficiency. Look:

Good luck with your plants

So if thats nitrogen deficiency, its normal at flower at mid-end right? they are at mid now. But what if its Sulfur or Iron deficiency?

What you think, are bud are enough big?

looking good imho. well it depends on the wattage used for light....

Should I water with nutes each watering?

I would recommend that!

By the way leaves are yellowing and some of them are dieng for some reasons. Is it very bad? Any tips why?

Guess thats cause of underfeeding them. but its not that bad for they are mid-end of flowering..

 

[Heart Of The MJ]

Ive used 2x 400w is that good?

 

[staff11]

How big are those containers?

Iron or Sulphur deficiency is rare.... doubt that is what is happening. They look root bound to me, when that happens you wont keep them green no matter what you do.

 

[Sour Deez]

^^ good point about being root bound possibly..

notice how the whole plant is going yellow, including the stems, N def causes red stems i belive

What else causes yellowing throughout the whole plant?

 

[PoopyTeaBags]

Looks like nitro def....

if your leaves are yellowing and they still have green viens its a mag def. my guess is you should water with nutes everywatering... they dont seem to be getting enough...

 

[mg75]

looks like root problems...
do you have bugs? gnats? root aphids? root rot?
did you pull out the plant from its base and look/smell the roots?
perhaps PH issues/lock-out

try a water and h202 treatment or a h202 and bleach treatment.
try a root stimulator such as rapid start or roots excelerator.

might be too late for extreme treatment and u should just nurse them until harvest.

looks like you have multiple strains. the ones that are yellow need more nitrogen an some calmag.
the dark green one thats "clawing" needs less nitrogen, an more calmag.

 

[StrapAssassin42]

all of these are viable solutions/problems.... instead of micro managing each little thing and trying to figure it out one by one.... i suggest leaching them...running approx. 6 times amount of normal water thru them... (cure any salt build up and ph issues)
Let them dry out thoroughly then hit them with a nute solution that has ALL micro nutes and has some nitrogen... of course P and K too
Are you letting them get reasonbly dry before watering?
If your watering everyday that could be an issue... if the soil is never drying out the roots are not getting oxygen...roots need oxygen!
overall they look pretty good for a only a month in

 

[Heart Of The MJ]

Thanks! Yes they dry completely in two days, so i water them each 2 days (one day pure water another day with nutes). Ok man, ill try that method. By the way, plants are looking same now (only few leaves dropped) i guess thats good

^^ when a plant is that deficient, flushing would only degrade its nutes even further.

^^ when a plant is that deficient, flushing would only degrade its nutes even further.

If he is feeding nutes with all of the micro nutes in them and he is still coming up deficient than it is likely due to a ph issue....
the best way to correct this (in my opinion) is to flush and start with a clean slate.

 

[StrapAssassin42]

Let us know how it turns out MJ...Good luck!

This is what I would say. Definitely looks like nitro def mid flowering because it started at the middle of the plant. If it were vegging the N the leaves would be yellow more towards the bottom leading up.

I actually have the same exact problem right now with a 1/4 of my grow because I did not add enough N in that part of the mix...I was being too cautious.

Whenever this happens I just water with teas containing the nutes needed until flush time.

 

[praisehim.]

the pics dont show a ph issue. you need more food.

 

[Heart Of The MJ]

I gave them nutes each watering, and they are getting better. I have one question, i have CO2 tablets, which need to grind and mix with water and water plant 2 times a week. should i use grounded tablets on water with nutes, or use pure water?

C02 tablets or pucks aren't supposed to be fed to the plants via the roots. C02 is for the plants to inhale. Like we inhale oxygen. Vice versa in plants. So the c02 pucks are used to make c02 in the air for your plants to soak up thru the leaves. Never used c02 pucks. I use Yeast Sugar and water to make c02. Works well for small spaces. Def could see a difference when c02 is added for sure.
