Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

Defficiency? 1st grow
I’m unsure of what is wrong with my plants. Leaves are turning yellowish colour and withering, first affecting old growth in week2F autoflower genetics. I use ph 6.4 water, runoff measured at 6.0.

Nutrient lockout?
Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Can rotating my 12 hour cycle back a few hours over the course of 3 nights harm my plant mid flower?
If i were to manually flip my lights on and off an hour early for 3 nights to adjust my 12/12 from 9am-9pm to 6am-6pm would it be detrimental to the plants? They are in the 5th week of flower. Rotating back 1 hour each night

Nutrient lockout or light burn?
Hi guys. I'm facing problems after problems :/ I changed my soil and some of the plants turned back from yellow to green, which was very nice to see. However, now leafs tips seems to burn and I'm wondering does it look like nutrient lockout or light burn? Thank you!

Early senescence on Runtz?
Based on your experience growing Runtz and/or the pictures posted below, what week would you say we're in? I'm asking cause leaves are yellowing and unless I overwatered them it looks like a very early senescence, no? I'm a newbie so there are obvious things I don't see :) Cheers

Is this a good cocktail for my next feeding? I’m having major nutrient deficiencies or something. These yellow leaves got me stressed.
