Nitrogen toxicity?

RallyAutosstarted grow question 5y ago

Are these dying leaves a result of the nitrogen toxicity or something else? Thanks for all your help!

Could be really bad light stress... My guess would be that a high PK nute has locked out calmag and other micronutrients. If you're using a booster, roll it back a bit. As always, check your pH and EC going in and coming out.

I had this before and although not entirely sure I put it down to a pk overdose. N Overdose looks very different - dark green claws.

Wind burn ?? Leaves are going down while looking healthy. The leaves on the top are growing normally. It goes down more and more. I dont understand if light is too close and she tries to flee it. Or she wants more light. Is it bothered by the fan ? is it dying ?

Hi guys, please help! Everything was fine with my plants, they are flowering for 4 weeks. But when I opened the box today, I found that one of them is not doing well. All the leaves are dropped down, and one branch dropped to the ground and almost broke. What could it be?

Weird looking seedlings? (uploaded vid)My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.

Wind burn or over water?The leaves on my plants are getting a little crooked. Look at the last photos in week 3 to see. My fan is in low pointing away from the plants. The little guys move around a little bit, but I’m worried it’s too much. Or am I overwatering? If look, you’ll see I don’t wander much.

There is something wrong with my plants but I'm not sure, I hope it's nutrient burn, iun whiuchn case I will flush with PH water, but it could be nutrient deficiency, what I am most concerned about is that this is root rot. What do you think it is and what should should i do?

To remove or not to remove Sooo, 10wks she is looking strong. Do I remove some of the bigger leaves that are almost 6-7 inches long or do i wait. Should I switch to other nutrients now or I have tiger bloom, open sesame, beastie bloomz and cha ching. I don't understand the feeding cycle it confuses me.
