Is the plant just maturing or something else?
I don't think this auto CBD plant has long to go. It's at 59 days of a supposed 65. I just started to notice a some tips beginning to discolour and a couple of fan leaves have small yellow spots appearing. Is this just the plant ageing?

My OG's are starting to yellow much earlier than I am used to. Pictures are taken on day 35 and they're supposed to be around 8 weeks of flower. Could the yellowing be due to high pH in the medium or maybe disease or am I just being paranoid?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?
Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more? I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.

我的女孩怎麼了,這個是生病了嗎?還是太多的餵食?
在他長出第二對葉子的時候這樣的現象就出現了,但是只有一邊有葉子,我查了相關資料顯示這是菸草鑲嵌病毒(Tobacco mosaic virus;TMV) 我覺得挺像的。但是不是很確定,我該繼續等幾天嗎?還是把葉子切掉。 誰可以告訴我解決方法,希望他可以度過生長期,因為他是自動開花,每一天都很重要。

Does that look like an early deficiency?
Hi everyone, what ya thinkin' What kind of deficiency could that be? My bet - potassium. last portion of water was ~6.2 pH I wasn't feeding her nutes for ten days by now. Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.

Ok, so I’m starting to see a deficiency. Yellowing between the veins at uppermost leaves. My ph is on par. I’m maintaining my grow per normal with one change. I added Carbo load at 2ml/g. Could that be the problem? I think I’m going to flush today and dump my tank. Restart.

Is this a Magnesium Deficiency?
Hi all, Day 98. Northern Lights. 1 of my 3 NL girls looks to have a bit of a Mg deficiency. I'm close to harvest so not too worried however it would be nice to have a confirmation for future grows/learning as I'm very much a noob still. Can anyone confirm/correct me please

Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.
