Split from : The Complete guide to Sick Plants,pH, and Pest troubles!

[bla4444]

You will get more help if you start a new thread in infirmary and fill the information about your nutes and pH at least.
I'm very newbie for your to listen to me, but i think you got some magnesium deficiency, but as there's a lot symptoms may be some pH lockout.
Hope someone help you more.

thanks for the information but i rather not tell ph/ec/etc because ppl tend to fixiate on that. and to be hounest: i can read the charts myself as well. which brings me to another point, because some information of those nut take up charts contradicts the next available chart.

i rather have a someone that can point me out what is wrong with the plants and letting me figure out how to solve it.

Hi, first of all : GREAT GUIDE !! thank you 4 sharing your knowledge

I need of an expert eye ..better than mine.. because I am unable to understand what my babies have..

I assume that all is depending from a PH imbalance in my pots.. it gone down till 5,5 since 2 weeks .. I'm actually fighting it whith Lithothamnium .. but I am still unable to make a diagnosis on what kind of nuts they ran out..

I post a photo.. hoping that it could help better than words..



Thx in advance for help

bla4444 without the pH balanced your going to have a multitude of problems. So that could be your problem right there, without proper pH your plants can't properly absorb nutrients.

to prevent mold

to prevent mold

hi all, i would know if a very good ventilation can fight a high humidity.
I red here on ic that many times during the night (of course while flowering) temps of many growers go heavily down and so hr increase, some times until 80 90 %.

However, i also red that many times a good ventilation can make miracles in preventing molds, even having a overwhielming hr %. Is it correct?

At last i would ask if it would be better to spray the plants with something against mold even if the problem still not appear, just to prevent i mean.

Thank you in advance for your advises

Hey mate hope all is good.

"They say" humidity should be at 40% in flower and towards end i drop mine to low as possible as like you said mold is a bitch.

For your humidity to go up 90% at lights off how cold is your room getting?
Do you not use a extraction fan to create airflow and control the stink.
to your question i would say yes air exchange should reduce your humidity.air circulation not sure that would help.

P.s. i "try" to balance my room lights on around 28degrees and lights off i try for 24degrees...

Very helpful

Very helpful

Thank you so much for this thread! I've used this thread off and on for years now and have many thoughts on how it could include some more pictures. Pictures of healthy plants, pictures of plants during stages of recovery, vegetable and flowering. Pictures on sexing and Hermes, comparisons of similar looking but different deficiencies and damage etc. ways of micro managing small or subtle issues with foliar applications. The many incorporations of compost teas...

 

[Ironlungs04]

The conditions for mold mildew require warmth and humidity sustained for some time but not along time. There is a very inexpensive way to control the mold/mildew, citric acid and brew yeast with phd water foliar lay applied. This is marketed as Nukem in stores. It eliminates the moisture content necessary for molds, kills spores by damaging them, bacteria in yeast eat residue. This also kills all bugs and can carefully be soil flushed. Putting an air pathogen filter in between the intake and the air port in your grow area helps a lot also. They are cheap and make a huge dif if not filtering with a can etc. high humidity is not always bad. If you read about transpiration during low humidity you will learn of potash deficiency. Hard to avoid this if always dehumidifying your space.
