Nutrient burn and what else?
whoawhoastarted grow question 5 years ago
RQS Northern Light Auto, 8 week-old (3 weeks flowering), Coco+Perlite (70/30), GHE FloraSeries + Cal-Mag, TS1000 LED 150W, 15L pots. Lady suffered from nute burn last week, but I think I managed it by dropping EC to 1~1.2. Now there are brown spots on upper leaves, suggestions?

@Fruitgrower @Nobody01 I thought about it too, but I only see those spots on upper leaves! Ca deficiencies should start from bottom, right?

It's because of your nute burn issue it's locking out access to calcium and magnesium. 🌱👍Give her flush and look at reducing your feed.

Based on recent behaviour, it could be a Ca deficiency. (between Ca and Mg, it doesn't look like Mg... a K-def is less likely, but would have spots like tha tlower on plant with some fading and burnt tips.)

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!10 months ago

Slow bud growthHey everybody would anybody have an idea on why my bud growth seems stunted? Like maybe it's just genes and it's a slower bloomer or what? That plant imho seems fairly healthy but it's just producing flowers at such a slow rate compared to its sister sitting right next to it
