Is it nutrient burn?
GuniGugustarted grow question 2 years ago
Week 9 I noticed orange/brown spots on leaves and tips turning yellow. Is it because nutrient burn? Was feeding them with all the Biobizz nutrients by their schedule. Second day, 10 week I flushed the plant. Should I continue flushing 3 weeks before harvest?

Looks like it's asking for some more p and k mate. I'm using BioBizz atm and they are not the most concentrated products out there. If you've got topmax I'd up that to 4ml/l the stuff is practically water with a tiny amount of pk per ml. But you could keep flushing it for another 3 weeks till it's finished, won't do it any harm.

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it

Yellowing on leaves tips. Should I start feeding her?Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

Possible nutrient burn ?I’m pretty sure this is nutrient burn but it’s weird because I’ve only given a tiny dose of nutrients so far. Less than a quarter of recommended dose and probably less than I’ve ever given an auto before. What do people think ? Nutrient burn ?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

What gave this? Light excess or nutrient burn or lack?I had this symptom from the beginning, stable, I didn't worry too much.
What could be the reason?
How to avoid this in the next grow.
I mean, it's minor, but might be better to attend and unleash a better result.
I have this on all buds, on canopy it comes with curly leaves.

Yellow / brown leaves tips; should I worry ?Hey ! My 3 plants (same strain) are showing yellow / brown leaves tips for a few days, and I'm not sure what it could be. I'm thinking mild potassium deficiency, or perhaps a bit too much nutes ?FYI, I'm strictly following Biobizz chart, every watering. Should I worry ? Thanks !

Balcony Auto Gelato with Yellow and Brown LeavesI'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?
