To start this off, the last couple of waterings have been watering til 20% runoff due to over feeding (I mix and topfeed within 2 weeks with GG 4-4-4) and now I’m getting this. Looks nitrogen deficiency to me but this is my first grow so I could be wrong lol
What’s the verdict? Should I worry about the light green/yellow?
Mature fan leaves look nice and healthy. I assume your concerned with the lighter color on new growth, which is normal in my opinion.
If im mistaken or missing something somebody more knowledgeable will chime in.
Yeah the lighter green is what was scaring me. Good to know it’s normal 
How many times have you overwatered with 20% runoff? I would say your worry about the overfeed is over with, since they aren’t clawing or tip burn. Perhaps the overwatering with runoff is causing the color you’re worried about? Unless you have some serious levels of drainage material (perlite etc) that doesn’t cause the plant any stress with overwatering. This is all apart from required drying out period that they need.
Honestly just from pic, they look pretty decent broski. Cheers!!!
Looks like the flushing did its job and now you have an immoble nutrient deficiency. Feed it lightly with some micronutrients with Iron and Manganese etc.
Whale darnnn. I did foliar spray yesterday with some Optic Foliar and watered in about 1/4 gallon of Recharge… just what I had on hand tbh, what’s your recommendation for application for these nutes? Should I top dress again or?
Give them a check in a couple days. Only do one thing at a time so you can actually see if its working. Looks like Optic has some micros.
I now have learned the need of micros and the difference between immobile vs mobile nutrient deficiencies 
Learning more here then sittin in a classroom lol
New growth it could be it will turn green soon enough.If your plants are hurting for nitrogen its gonna start i the lower leaves yellowing out and going crunchy.You look fine
I have a bunch doing that from a repot.They had a growth spurt they go to green in a couple days.The big one in the back the White truffle/icecream cake does this all the time.Perfectly normal man.
Yeah I wish I knew the strain. Clones of bag seed that I threw into a mix of others. I know for sure most came from a pack of supposably Sour D
Any updates on this plant ?
My bad…haven’t been on in a lil. Starting see some rust spots. Wondering if I just need to top feed again? Idk kinda lost on what to do.
Feed it once with a soluable plant food like Jacks. That definitely aint normal growth.
Also wondering if I should start feeding some bloom nutes and flip within next week.
You will need bloom nutes when you see flowers. You need a balanced feed for stretch before flowering.
Yea id do what they say until healthy and not flip or you’ll regret it like i have before.
Yellow new usually means iron deficiency so flush seemed to fix ph or lockout not sure what readings you’ve tested. Sulfur deficiency also can cause yellow but different area i recall.
From ai…What caught me is N toxicity it saw…i zoomed in and lower fans are almost purple.
Id start from basics, temp, rh, root temp, ppm runoff, Par, ph run off etc get closer to optimal
The image depicts a cannabis plant (Cannabis sativa or indica hybrid) in what appears to be a controlled indoor grow environment, such as a tent with overhead lighting and possible irrigation tubing. The plant exhibits vigorous growth with multiple branches and fan leaves, indicating it is likely in the vegetative stage. Key visual symptoms include:
These symptoms are inconsistent with broad deficiencies like nitrogen (which typically yellows older, lower leaves first) but align closely with localized issues affecting nutrient uptake or excess in the root zone.
The most likely cause is nutrient burn, resulting from overfertilization or excessive nutrient concentrations in the growing medium. This occurs when the plant absorbs more salts (e.g., from fertilizers containing nitrogen, phosphorus, potassium, or micronutrients) than it can process, leading to osmotic stress and tip chlorosis. Symptoms typically start at the leaf tips because that’s where transpiration is highest, concentrating excess salts.
Mechanisms:
Evidence from Image: Yellow tips on upper leaves (top-down progression) indicate toxicity rather than deficiency (which is bottom-up). This matches reports of nutrient burn manifesting as yellow/brown tips without full leaf yellowing.
Diagnostic Steps:
Solutions:
While nutrient burn is primary, other factors could contribute or mimic symptoms. These should be ruled out systematically.
pH Imbalance:
Light or Heat Stress:
Micronutrient Deficiencies (e.g., Iron or Magnesium):
Watering Issues:
The plant’s symptoms strongly suggest nutrient burn as the core issue, with potential compounding from pH or environmental factors. The plant is not critically damaged and can recover with intervention. Monitor new growth over 7–10 days post-correction; if symptoms worsen, consider tissue analysis or consult a grow forum.
| Issue | Likelihood (High/Med/Low) | Key Symptom Match | Corrective Action |
|---|---|---|---|
| Nutrient Burn | High | Yellow tips on new leaves | Flush medium, reduce fertilizer |
| pH Imbalance | Medium | Tip chlorosis without full yellowing | Test and adjust pH to 6.0–6.5 |
| Light/Heat Stress | Medium | Upper canopy affected | Adjust light distance/temp |
| Micronutrient Deficiency | Low | Minimal interveinal patterns | Supplement after pH fix |
| Watering Problems | Low | No widespread wilting | Optimize schedule |
Prevent future issues by using a balanced fertilizer regimen (e.g., 3-1-2 N-P-K vegetative) and regular EC/pH monitoring. If growing hydroponically, maintain reservoir stability.
What about epsom salt, gypsum, and azomite?
I would say a PH problem. Therefore it is blocking the magnesium and you see the Mg deficiently.
