Hello, i posted a question last week to Better ude...

Stay at 2/3 of the nutrients, with every feeding and preferably feed a whole chart of your recommended supplier, otherwise you have to correct pH and ppm also. Tapwater has the wrong pH to feed it directly, you would have to correct it via ph +/-.

Hello mate, i'm pretty sure about your problem, i have the same answer that i already gave you 2 weeks ago. At this point i think you have something bad in the plant roots, probably the imbalance of your soil allowed a lock-out of different nutrients leading a this burns. Your flower seems to be hit by botrytis. Good luck!

Pretty sure you have a pH issue. I suggest you flush out the medium using pH balanced water. I would suggest running 4-5 gallons of water though it. I do this outside or at a sink to let the water run straight out. Once you have flushed out the soil to correct any issues, you can then start with a lower dose of your fertilizer while she rebounds. Since it is likely not growing nearly as much you will not have to give much fertilizer at this moment. Hope this helps.

Hello! Okay my guess after looking your diary. You fed 3ml bio grow and fish mix in week 4, 3ml grow in week 5. next to the flower nutrients, i think that's just too much wrong nutrients in that stage. I would do this, if you place it right in front of me and asked to safe her: Correcting the root zone pH level, flushing it until 1-3L depends on size of the pot coming out with pH corrected water(good videos on youtube) with the right amount of nutrients in it (online Biobizz feeding chart) I would, if you can add some Potassium, PK 13/14 would be good the damage on the leaves will never recover, thats "dead flesh". You have a automatic and there isn't much to do... you just need to make the best out of the situation Good luck! (:

What is your humidity level?
