Description-
Growing indoor (LED light)
Just Completed a Flush 2 days ago
Miracle Grow soil (Switching to Fox Farm Ocean forest)
1st week of flower stage
75 degrees 55% humidity

A few plants are showing signs of what I think is Phosphorus Def.
Photos are from Two different plants, some of the worst leaves.

I looked through the stickies but not 100% on what the issues is.

Thanks for the help .

Thats definitely a possibility. Flushed the plant with water around 5.8-6 ph. The soil was at ph 7.0 prior to flushing.

give it some micro nutrients (zinc iron cobolt copper) and some cal-mag.

and again, make sure ur staying within a .4-.6 -ph fluctuation range max.

max.

There are different types of MG. If it is the type that has extended feed for 3 months you are going to have problems flowering. I haven't seen anyone be able to advise on how to successfully flower with that stuff yet. If it is the regular MG potting soil without extended feed you can get through fine with good watering and feeding habits.
Next grow you will do much better with the ffof.
ffof is a water only soil for the 1st 4 weeks.
Good Luck!

N tox (curling, puffy and too green leafs) could be temp,Ph or over feeding or wrong formula. So...
If your Temp is to high the plant will bring in to much water and with that water. Too much nutes.
If your Ph is to low the plant can only bring in the nutes that are available at that Ph range (N in this case) and on the other end of the scale will not bring in anything .so... Def

As with any def there are always other signs of other def. too. Maintaining Ph will remove most def without any fancy products.
It is always a bad thing to go into flower with def so
Check out groweedeasy that is where I get most all of My answers.

I would go back to veg for 2 weeks and train that plant down so that it is receiving as much light as possible evenly over the few tops that are there..
I am assuming that you are using a very low watt light so 2 weeks might not even be enough..
What ever you do. Do it using the KISS technique. This is all about looking at how you are maintaining your plant.
Ph, watering and temp is key.

Good luck, (:

When I started I was using a low out put light setup. Was my mistake. I have switched to a LED light. 400w equivalent.

The MG soil says feeds up to 6 months....

I do think it is a PH issues. Looks to be to Low around 5.5. Should I ph correct my watering to about 6.5 and bring it up slowly? Ph correct to 7.5 and bring it up faster?

People on other sites are recommending 20-30% perlite to your MG soil as well. that have stated that they are adding flower fert at low dose at the start of flower.
There is also some mention of Ph problems.
I recommend that you repot into a 20-30% mix and add some dolimite lime to naturally bring up the Ph
This will get your water pouring through your mix and drying faster (the plants love it)!
There are some other down sides to using MG soil that were mentioned as well but, We can just disregard them.
Keep up the good work and don't panic. Do one thing at a time..
Also like I said, try to pull that top down and get the lower tops to catch up. You don't have to break anything just persuade her to let her friends come and play. You will get better light coverage and faster growth.

Good luck

So is there anyone on this site who has successfully harvested good buds with the time released MG?
Just curious if you can name someone because I would like to see someone who has had success with it since I have yet to see it.
Not talking about regular MG only time release.

Not sure if you will get a response on this guys thread. but, there are people out there that are growing and finishing with MGTR. Perhaps not on his site but...
I had some time to look up the topic for Eflow as I was curious what the what is MG soil. Now I know.
I am no longer a soil grower. It's to slow and messy indoors IMHO.

Peace :peace:
