Is this Light Burn or a Nitrogen Deficiency? For Science!
Prilyfe13started grow question 10 months ago
I have canoeing leaves from either light burn or a nitrogen deficiency. The 240 watt light is close but at 50% and the the deficiency is from taking out veg nutrients. Is it fine? Or should I drop my intensity down even more?

High bro, you give too much nitrogen I can see that from the dark green color from your leaves. I just checked the Advanced nutrients and you need to stop giving the Nirvana nutrient to prevent more damage in the future due Nitrogen toxicity. Next to that you just need to do what you have been doing your plant and diary are looking great!

Too much N..clawing to bits. Nirvana is for early stages. + sensi calmag + has N in it. And holds a high ec value. You need to be mindful of so much nutrients at this stage of growth. You're in ripening.. you should be winding that amount down.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

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?

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Looks like light stress I assume with the canoe and curl. Moved light from 100% to 75% Stil at 35in from canopy. Should that do the trick? Also should I have already had it at 75% and moved it to 100% during flower? Or how do you guys do your light power

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answer
