Idk if this is normal or not
My white widow auto is in week 4 of flower and her leaves are yellowing. I just gave her a dose of bloom last night with ph water to see if that would maybe help but honestly idk if that was even the issue. Someone help 😫

Yellowing leaves
Hey fam, Just ended 3 weeks of flower for this Banana Purple Punch Auto. A heap of yellow leaves basically appeared over night. I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow. What do you think?

Leaf Discoloration - Hopefully Nothing
I'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage. Focus on the yellow/brown discoloration, actual physical damage is accounted for. More details in main post.

Can't deal with yellowing leaves in 4th week of flowering
Been having this problem for a few weeks. I suppose its deficiency of Mag and for the last week or so I've been giving increased portion of CalMag (for 1.5l of distilled water TriPart grow 2.1, micro 2.1, bloom 3, Calmag 12ml). Should I give them more time or its something else?

Brown spots on lower leaves - ph fluctuations?
I have discovered some brown spots on the lower leaves. I suspect it might be down to ph fluctuations - first time growing DWC so probably my bad! Does anyone agree? I should also add - I did a nutrient change a few days ago and for the first time added calmag & silicon

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?
Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own. I’m not sure if it’s a nutrient deficiency or blockout from ph or something else. I watered them only with water ph 6.5.

Heading into about 3rd week of flowering and seeing some yellowing
About 3rd week of flowering but I have been seeing yellowing leaf tips starting on top newest growth first and now seems like I'm having older larger leaves yellowing and burning now. Not sure if this is lockout or a deficiency or something else?

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

burnt tips/yellowing
My GG4 Auto has burnt tips and some yellowing on leaves. Just came back from a week and a half trip and RH was 35% and plants were pretty under watered. Is this nute burn? or from underwatering

Yellowing leaves after first Mainline top. Light stress?
Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!! I have raised light to 23". Am I on the right track here?

New growth yellowing? Or am I paranoid
I'm really unsure if she's getting what she needs, New growth kind of shows a deficiency maybe? Using 4-4-4 and 2-8-4 Organic mix in the soil. I'm about to buy stuff to make a compost tea for them. She was healthy up to week 3, now showing this yellowing 🤷♂️ Thanks for help
