Drying out the soil medium can do wonders to killing a lot of pathogens as well and is part of the point behind watering then letting dry right out then watering again. But if it is root rot it will be hard to spot in soil unless you want to pull the plants out of the pots and hopefully you can...
They are fairly safe to use, but like chemically derived nutrients, if you over feed with them your buds will taste like shit and you will need to flush again or a long cure.
marijuananation has given some good advice. Also remember to regularly treat from now on with the recommended dose of hydrogen peroxide. Every 4-5 days. Some would frown at this but once you have root rot its difficult to totally knock it out, so its better to prevent it from the start, and once...
Extended periods of soggy roots will cause plant roots to stress since plant roots will be deprived of oxygen. Deficiencies begin to appear and get steadily worse until all nutrients are locked out. If not remedied, then after a while plants stop uptaking water altogether, roots go rotten and...
What is the chemical in the pH down? A pH of 7.3 isn't going to do too much to your plants by itself. Are you letting the soil completely dry out before watering again (as in the pot goes light before watering)?
Depends if you have overfed them. It is still possible to do (but not easy to do) even with 'organic' nutrients. Really cant help much more unless you can get to the roots for a looksee.
Organic soil does not mean that it has organic nutrients in it. All soils are 'organic'. The list of stuff in the soil is not enough to sustain cannabis. If you have not been feeding your plants then you do not need to flush them since you ARE flushing them already.
Apart from the low pH which you need to fix (6.5 to 7.0 is what you are after), tell us a bit about how many times you are feeding / watering your plants?
Also tell us a bit about:
Light, air, humidity and heat.
Clones that take longer than 2 weeks to show roots can often have diseases from using a non-sterile cutting instrument, or sometimes this can happens when plants come from a mother that was already in flower or too high in nitrogen.
Since clones only ever really to be foliar spreayed with...
Like a lot of charts, it misses the three most common causes of plant problems when growing cannabis in soil.
1/ over watering: roots sitting in water for long periods of time due to bad drainage or to regular watering
2/ over feeding
3/ incorrect watering where the medium is not thoroughly...
A few questions for you. What is under the clay pellets, is that rockwool and if so how much rockwool are you using in comparisson to clay pellets. Also, since you are essentially growing in hydroponics why is the pH so high? I would have thought a pH of 5.5 to 6.0 was the usual range for hydro...
Two questions:
- Does that soil contain slow release nutrient why you are not feeding any nutrient to your plants manually?
- Are you allowing your pots to completely dry between watering?
Two questions. Firstly, what color are the roots? Are there dark patches in the roots, are the roots smelling? Secondly, what color are the tricones? If theyre amber or even the tips of them are amber, then flush and chop down.
imho I think when you see those little leaves curling like that it often can mean that the roots are not draining properly. Are you finding that they are sitting for long periods of time with wet feet?
When you are growing cannabis in larger pots you do need to keep an eye on how much nutrient you are feeding them. Being that they are in larger pots means a larger root area and that means a lot more nutrient is being used because you are literally feeding them more water/nutes when you do feed...
1/ Wrong soil type, you need fast draining soil not hay based garden soil.
2/ Unpredictable light cycles and weak light: Cannabis needs 16 or more hours of light every day in order to remain in vegetative mode. Cannabis also needs a solid source of light and unless your window gets direct...
