NEED HELP! CRUCIAL PHASE

CHILLING_RACOONS
CHILLING_RACOONSstarted grow question 2y ago
Excess or deficiency? I'm in the crucial phase of buds development, some leaves are getting brown and seems to be burned but I don't know if it is a burn or a deficiency.. On 17/01 I gave 2ml/lt npk 4-8-8 and npk 1.7-0-3 1ml/lt? What should I do? Could someone explain? Thank you❤️

This is the start of a potassium deficiency ... she's needing a good PK booster at this point - something like General Hydroponics KoolBloom liquid which has an NPK of 0-10-10... the dry formula of that is used in the last two weeks of flower and it has an NPK of 2-45-28... PK boosters really target the bud development and are usually started around week 3 of flower which is just where you are! Don't expect the damaged leaves to repair themselves, they won't - but if you get some PK going, the damage shouldn't spread more after a couple of days... Good luck!

Yea. Just some minor burned tips. You’re ok my man. The leaves are telling you it’s absorbing max nutrients for the current day and can’t handle any more. I max my plants as well - and when I see this - I give them a nice 2 day feeding of plain ph water to absorb what ever else is in the bag and then continue on with elevating nutrients. They will adapt. Like grannie said - it won’t repair - but who cares…ya don’t smoke or save that stuff mostly anyways. Focus on the buds. I, becoming a fan of tps signal for end stage bloom. Ran it with two plants - one has it - one doesn’t….and the results were amazing. It’s drying now - but I think double yield. Safe during flush.

Your tips are burned so you must be giving enough if not slightly too much nutrients already. The burned edges indicate potassium def but I have a feeling it’s due to bad ph in the medium rather than not giving enough
