I know i was poor on nutrients from the beginning because of the country which i am living in now.


I will start using Bio Thrive Bloom tomorrow. Am i late or can i still get some results ?

All the best.

Looks like nutrient lockout, do you monitor your PH and EC ?

Looks like cal/mg to me. The brown spots on the leaf give away the calcium and the yellowing of the leaf in that way sure is a sign of a mg diff. You need some cal/mg nutrient or epsom salts and molasses.

Light green leaves is caused by low nitrogen so if your starting bloom nutes you should also give her some nitrogen along with calcium.

It all started in flowering stage. I was using some nutirients. Now i understand they didn`t help. You can see the plant is 35cm. Now i am planning is using Bio Thrive Bloom, i ordered it is coming tomorrow. I flushed twice to manage PH to normal levels. At least i hope

Do i still use molasses and epsom salt or this nutrient will be enough ?

This is my first grow i made a lot of mistakes and i am still learning form them. Anyway is there a hope to smoke one or two joints after all

Thank you then i can mix some Bio Thrive Grow too. May be half dose grow half dose bloom for a couple of weeks ?

And can you please say roughly how far i am from harvest ?

You will need to use cal/mg as well as the Bloom. It looks like you have a bit of N diff going on as well as Namvet pointed out. You should really get your self a ph meter other wise you might not be able to stop the problems without knowing your ph.

Ditto to what Nam' said,..there's more than one defc. here, but N is most glaring! Whatever nute's you have, blend a mix that has something close to even numbers (like 16-16-16, not literally, but you get the idea), so she can get N-P-K, along with something with Ca in it.... N is still very important during flowering, just not the MOST important at that time.... feed her, and she'll still get you a small jar of smoke!

Thanks for all answers. Now i get the idea. I will inform you with the result.

You can have all the nutrients in the world if the PH value locks them out it wont help the plant!
So I recommend doing some foilar feeding and buying something to measure ph run-off!
