Nutrient burn?
Stonerdanswered grow question 4 years ago
Can't really determine what's going on from the picture but from the diary it seems like your plant suffers from a Phosphorous (P) toxicity! - top leaves grow thinner with interveinal chlorosis while Calcium (Ca) and Magnesium (Mg) deficiencies are showing at the mid-bottom of the plant.
I'd suggest lowering the "Aqua-Flakes B" dosage by half and checking it daily for any improvements. If the problem gets better then keep going until she looks completely healthy then start increasing slowly as the plant matures, if it doesn't get better then try flushing your system and providing her with tap water for a couple of days to clear out the toxicity (this may cause deficiencies of other nutrients so be careful!)
Hope this helps! Good luck and happy growing :)

980ppm is high for that size of a plant . Dial it back a bit and growth will increase . I'm coming up to mid flower and the plants are at a decent size . But they're only getting 1.4 EC. less is usually more .

It's looking like a little nute burn from the yellowing tips. Maybe back off a little and should be fine.

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Curl and clawing,N-Toxicity?Flushing?Hello Growers!
Last week I gave around 1ml/L BioGrow in 600ml water. Now all leaves seem to me dark green. Some are disformed/wavey and show burned leave edges and slighty burned Tipps. Two of them seem to be handling the high nitrogen. But the third is curling/clawing. Wdyt?

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Yellow leaf tips in flowerShe's pretty far into flower, in DWC, and the environment and nutrient schedule have stayed consistent for a while now. I'm using GH Flora Trio at 5ml of Micro, 2.5ml of Gro, and 7.5ml of Bloom per gallon.
The leaf tips are looking burnt, should I ease off on nutrients or what?

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!9 months ago
