definitely next grow ditch that freekin miracle grow potting soil that stuff is deadly due to the fact that every time you water regardless of whether you nute or not your feeding the plant
and then when you nute the plant your doubling the dose and also fucking up your blooming nutes and during flowering it is feeding your plants VEGG nutes while your trying to get flowers causing them to be all fukt up and wispy
This is true about the MG soil and the time release nutes, they do suck! That's what I accidentally used for my first grow. It still turned out nicely tho!
But using VEG nutes in flower isn't always bad. I often use VEG nutes during flower. My nutes NPK values are as follows, VEG=24-8-16, Bloom=15-30-15 I will usually make a mix of half strength VEG nute with half strength FLOWER nute if I see some leaves loosing a little bit of their greenness. It is more important to maintain a healthy looking plant, with green leaves, than it is to feed straight flower nutes (trying to fatten up the buds) and loose the greenness of the leaves. Because if the leaves are not green they are not doing what they are supposed to do, which is helping to fatten up them buds! No healthy leaves=No healthy buds
Stated by Uncle Ben in his (Gardening Tweeks and pointers) Thread: "
Foliage production - Grow for the most amount of foliage you can going into the flowering response.
Maintain those leaves in a green and healthy condition up until harvest,
even if it means switching fertilizer to a high N value, like a 9-3-6...
If you can find the post that's called something like (What is the best NPK) And read Uncle Bens posts you will learn ALOT! Shit man, just go read all of Uncle Ben's threads. They really are a wealth of information!
Sorry OP, kinda got a little off topic. I'm not sure
exactly what's wrong with your plant bro. But if I was in your shoes, I'd be doing a flush. Then when you water next give it like 1/2 strength nutes of just the power plant stuff, not the other stuff.
Just my $0.02 anyways. Take it or leave it. Always tho, ALWAYS do what YOU think is best for your plant. This is just want I PERSONALLY would do.
EDIT: And if you have been feeding nutes 3 times a week, there's your problem! Feed nutes only once every OTHER watering, at no more than once a week. Some people say to only feed nutes once every 2 weeks, and just to make you really FEEL the difference, that's only 2 times a month!... It looks like you may have to much P just looking at your nutes NPK values.
Hope all works out for you, I'll be keeping up!
