Hey all... 1st time indoor grower here. Noticed these sugar leaves starting turning brown and hard/crispy, 2 days after using a bloom fertilizer. I suspect nutrient burn, but would love opinions from more experienced growers!
I did increase the amount with the latest feed, unwittingly thinking that as the plant got larger it would require more nutrients.Did you increase the PPM on a feed, deviated from the normal PPM target? You are in flower and the last thing you want to do is increase PPM. If anything, always aim to lower PPM in flower. But never increase it in your feed. You can lower other nutrients and increase another but you need to stay pegged to a PPM regardless. You shouldn’t chase nutrient deficiencies in flower, much. You should focus Ph is proper over chasing deficiencies and adjusting nutrients.
Keep nutrients on schedule and monitor Ph And PPM every runoff. If PPM rises, lower nutrient strength (PPM). If Ph falls or rises, feed offset Ph. Check runout every watering/feed.
Flower is boring but we cannot forget that there is other focuses in this stage. Ph being proper is amongst the most important when in flower stages.
The plant has enough stored nutrients, you really don’t need to worry about Slow fading/discoloring leafs. Therefore not chasing nutrients. Leafs are not the focus in flower.
You know the PPM you kicked off into flower, it should be 100-250PPM less when you reach end of Mid (week5) and slightly more less in Late flower (week6). The variance or total decrease is going to be determined how aggressive you were in vegetation or the PPM you kicked off flower with.
so do i need to address any of the "burnt" sugar leaves? This is most prominent on the colas.Besides, if you flush, by week6 you should be tapering off your nutrients to the end and dropping temps and humidity. They should discolor.
I see nutrient burn with twisting, curling and burnt tips. The burnt and curling tips look fresh as I do not see prolonged tip burning on the rest of your leafs.
Short answer. Lower PPM.
And that is a legit way of thinking.I did increase the amount with the latest feed, unwittingly thinking that as the plant got larger it would require more nutrients.
U know what, I think I'm gonna agree with u. Because I am flushing right now. And I have to say... I would sure like to add some nitro , I've never flushed prior to this. And never had the problem where stocks would not hold my buds up.flushing is non sense and only affects the plant negatively..
I measure the distance from the top of the plant to the light and it is always 12 inches or more. Yes, it did happen in 2 days, and since this post was originally posted it has gotten even worse (i originally suspected light burn and raised the light all the way to the top of the tent). I was feeding her "Alaska Morbloom" which is a 0-10-10, once every 2 weeks. I'm 99% sure I over fertilized and it burnt the dickens out of the plant. At this point, fan leaves are curling from the tip to the center and becoming crispy as potato chips. I've been pulling everything off that is (i'm assuming) dying, not sure if it can be saved or not.it’s your light being too close and not feeding correctly..
and that didn’t happen in 2 days, probably started a couple weeks ago and went unnoticed or was ignored..
what’s the light and the distance?
what have you been feeding? how much?
