nutrient burn and stunted growth- help
berlinbeginnerstarted grow question 4 months ago
SD2 has had nutrient burn for 2 consecutive weeks now which stunted her growth as well. I flushed her with tap water already but she is still growing slow. My question is what can i do so she recovers fast and grows normally as i was gonna flip them to flower in 10 days? Help

The two smaller plants are getting way too much light, so i'm going to guess this is actually light-related and not necessarily nute-related.
Also, the one plant looks more yellow on the side that is twoard center of tent vs side near wall. More evidence to support the light being the cause if it is not a trick of photography.
Regardless, i can see that the two smalelr plants have nodes that are way too tight and that happens due to too much light. They are also extra pale, anotehr sign of too much.
flushing probably just slowed them down more. no biggie, live and learn.
Get the light right, and that plant will perk up. I'd do that first before adjusting any nutrient concentration, unless it takes a nosedive. Better to do this 1 step at a time. Fixing the light situation may fix everything.

First, let’s not flush soil anymore, flushing is for coco.
At this point your soil is so soaked it will take a couple of days to get it back to a workable dryness.
Once there keep your nutes in the 400-700 ppm range and ph 6.5-6.7
Try not to overwater soil.
Best of luck with your grow.

mycorrhizae, micro nutrients, stabilize ph. i would use great white from planet success and biosys from ecothrive to sort uptake and stimulate roots. triple check ph meter, they lie and force mistakes.

No, not really.
It's more of a lacking.
Sulphur looks a lil off
As its soil Epsom Salt will give it a boost so it should be more vibrancy in her.
Also, fems only need 450-500ppf max. Even pre flower you only need that. 50% ish. Or 25-35k lux using a phototone app. (U won't get an accurate ppf) but you can gauge its straight by seeing how high the lux goes at 100% and 30cm away (or flowering hight, some new lads can go 20cm most 30) and use the lights ppfd map. And using your lux meter. You'll be able to work out its ppfd by taking its highest lux from set high. And you can use the lux gotten and lower it to come in line with wanted ppf.
Also, a good way to know if your plants are light stressed, if they droop really bad and the longer they stay like that after lights out will show u how bad it is. You should only want to see a lil sway after lights out. And within an hr the plants leaves should be standing up.
These 2 things u need to fix
Epsom salt or calmag
Also a micro nutrient wouldn't do you any harm or enzyme to help uptake

Hello berlinbeginner,
I do agree with the grower below.
300 watts on 25 cm is not ideal. You want it on 40 cm distance from the plants.
You can test it really easy with the hand test. With the hand test, you place your hand where the plant is for 30 seconds and if it’s uncomfortably warm for you it means you need to move your lights further away.
They should recover in the next 10 days so you can flip the girls to flowering when they are happy and healthy.
Happy Growing Buddy! 💚

The light green looks like nitrogen deficiency

I’m not seeing any nutrient burn here? All I see is what looks like a hungry plant, that’s also too close to light if it’s really only 9 inches from it at 300 watts
