Yes from what Ive been reading it sounds like ProMix has added Dolomitic lime to help keep the PH up. Maybe Ill add a spoonfull of extra lime just for more of a PH buffer zone.
So since StinkyAttic seems to be the resident soil guru, does she have any idea what might be the cause of these problems? I know she responded in the other thread i bumped up, but now there are pics in this thread.
ANy help is very very appreciated.
Thanks!!
I have seen very similar patterns of necrosis on plants that were kept in a closet with insufficient fresh air movement and bad heat spikes, likely compounded by over-use of foliar sprays, including rotenone (lol I'm not exactly organic atm hahahaha).
ProMixBX is pH stabilized, yes.
Next time your soil dries out to where it needs watering, flush it and feed with a complete fert with micros. Get MORE air movement around those plants and watch new growth for signs of improvement.
I know plenty of people who have been fine using the ProMix BX but I just don't like how peat holds water. Plus the pH issues but the water one is a problem with promix too. I find that it becomes waterlogged too easily, and personally prefer 60-70% compost and 30-40% perlite, which is naturally pH buffered in range and dries out well.
Remember that cannabis- and almost all potted plants actually- wants to get fairly dry between waterings.
Thank you so much Stinky!!!
Im a bit worried about using comost only because Im afraid of overnute'ing the plants if Im also gonna use GHGro/Bloom/Micro as my nutes from now on. I was thinking the ProMix may have been a good bet. Im thinking of leaving sterilized rocks at the bottom inch of the pots to help ensure quick draining.
If Im not going to use ProMix, is there any kind of compost you would recommend that maybe wont give me too many nutrients in the soil already.
Thanks again!
Also Stinky,
Do you think that my babies may not have been drying out due to the extremely high Humidity I have had lately. Also the corner they are in in the yard doesnt get the best air circulation, just a very slight breeze. Should I hook up a fan outside? That may be a little obvious.
Im sure If I was growing inside with HPS or MH the soil would be drying up quite quickly. Damn nature and it giving me some crappy conditions. I envy all you indoor people. :)
I think the compost I'm using is 1-1-1, just cheap shit (literally) from agway. The package says 'composted cow manure with humus' and it is $2.50 for 40 pounds.
You know, part fo the problems with overferting come from salt buildup and the chemicals in the fertilizer interacting. There is a chemical in compost that helps prevent unwanted chemical interactions. PLUS if you are running enough perlite, you can flush very easily, so and buildups you have will be easier to clear.
Also if you see signs of burn, back off on your fertilizer- same proportions, but add more water so the dilution ends up weaker.
Stinky so rocks....:thumbsup:
Rock on!
I had the same prob with 2 plants I kept in a bag with virtually no light for 2 days. I think it must have been heat or something as they were in the trunk of a car.
Regarding soil mixes my favorite is
60% Sunshine mix all purpose (similar to promix but doesnt get waterlogged like promix...I tried both side by side)
10% perlite
30% composted manure
I didnt have access to it but next time I plan on adding worm castings to the mix.
50% Sunshine mix
10% perlite
20% Wormacastings
20% composted manure
I think this would make a great mix. The plants in my log as curently growing in the a mixture of natural soil and the first mix I mentioned.
JMO Happy Growing
hey stinky, thats why peat is good for outdoor. it holds moisture. but of course i dont test my ph either. yet.
oops i spoke to soon, im having my own problems right now and from what ive read it could be part of the problem.
