answered grow question 5y ago
3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

Single brighter/yellow leaves while flowering
Hi fellow growers, Again I have to kindly ask for your help. She's in week 7 now, the 2nd week of flowering. I've noticed only the two largest leaves to shift towards a brighter green, almost yellowish. I'm hoping it's because of the flowering but I'm far from sure. Thanks

Veg Nute Issues
Has anyone seen any diaries that catalog a successful sick veg -> healthy flower recovery? I'm curious to see how sick growth transitions to healthy growth over several weeks. Current issue: a) LED intensity, b), N excess, c) PK def, or d) cal/mag def(rust on leaves top and btm)?

Calcium Def/Wilting or other issue?
So after 24 hours of feeding it CM Plus it doesn’t look any better. I’m hoping there is not another underlying issue. Environment remains the same. Pics are 24 hours apart. Or will it take a few days + before seeing improvements?

lower leaves yellowing in 3 days?
Over the past 3 days my 2nd plant lower leaves started to yellow. Both are fed the same amount and the same rates. I noticed the one that is yellowing the leaves are upwards and that is a good sign, but the lower leaves are yellowing too fast. I am unsure what could cause this.

The clone has bad leaves. Need help
Tell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Calmag Deficiency? Yellow Spots
Last res change I saw some yellow/brown spots on the fan leaves up where the main cola was getting too close to the light. Is this a calmag deficiency or light too close? I moved the light up to the top of my tent with zip ties and got back several needed inches. See pics.

Lockout or not enough nutrients ?
Hi grow fam, I’m starting to see some slight discolouration on a couple of leaves. I’m wondering if it’s being nutrient deprived or locked out. I am leaning on the side of caution by using GH’s light feed schedule. No signs of root rot inside the bucket
