Hi buddy, Now, I'd say be very careful. Sounds like you should of just flushed her with straight pH'd water as you already have nutrient burn. Instead of me going into all the problems here, i'll give you the solution. At this point, FLUSH with plain pH'd water, only when growing medium is dry.. Get your run off water somewhat clear as I bet it won't be due to the amount of nutrients built up ( this will eliminate any potential problems later down the line in flower which could be a big problem for you and could cause major problems at the roots, nutrient lock out etc. Then give her time to perk back up as she will droop after flushing. This could be a day or 2. Theres NO point adding nutrients when she is already burned, back them of and she will thank you for it. After a couple days see how she is and give her another water feed before then giving her a less than half strength dose on the THIRD watering. Things should get better, keep it simple. When things go wrong, go back to basics as all a plant really needs to grow is, water, light and fresh oxygen... It will ALWAYS grow without nutrients. Less is always more. Hope this helps. Good luck!

I’m not writing an essay like everyone else here. Your into flower and at this stage they are really looking for nutrients. Yours is showing a mag deficiency but seeing how it’s flower instead of cal/mag you should be giving her mag/sulfer to help her fatten those buds up

Hey there so I read your week and see you get the nutrient problem. Of coarse flushing and backing off a bit is best. I see your heat and humidity aren't out of control, so that leaves me with root troubles. Biobizz doesn't seem to have a root cleansing product..other than maybe the "root juice" however there are other companies that have some products that basically blast out the built up salts etc around your root zone, cleaning it up and making it a more peaceful environment. Fox farm has a product called sledgehammer and boomerang, they are meant to clean up what's going on beneath the surface and also to help the plant bounce back. I'm sure buying more stuff is frustrating, so if you don't want to do that then yes, flush maybe a couple times, and then slowly add back your acti-Vera and alga-mic with a little cal mag. I heard ground up egg shells can be a household substitute for a cal mag sup. Best of luck I hope she fixes up for you.

First, you might not have noticed it, but along with those spots, there are many leaves with burnt tips and / or edges, which a classic sign of nutrient burn, either because you are feeding too strong a solution or too often. You don't mention anything about EC/PPM, so you are not measuring it? It's true that Biobizz is low on Calcium and magnesium, mostly because most people get it from their tap water, but if your water source is on the soft side (mine is) you need a Calcium / magnesium additive. Those purple petioles (the stalk that attach leaves to the stem) are a classic sign of low magnesium. The only way to be sure is to measure your tap water EC/PPM levels. If you don't have an EC/PPM meter, my guess would be on the flush with Epsom salts you used. Those salts are very strong without a proper way to measure it, you most likely used too much. Also, with a 25 liter pot full of soil , if it's a pre fertilized mix (like biobizz allmix) it's probably too early to give so much nutrients, since the soil still has enough to feed the plant on it's own.
