Gelbe Verfärbungen der Blätter
I discovered some strange yellowish discolorations (like camouflage) on the leaves of one of my plants. It's currently very hot in the tent with up to 30°C, otherwise I've been watering according to the BioBizz feeding schedule like I have for the entire grow. Currently: Temp. 28.9°C RH 35%-42%

Leaves Turning Yellow - RQS Watermelon Auto
Hi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

Is she too far gone or can she come back?
Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

Leaves keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

Yellow edges to leaves
Hello fellow growers. I have noticed some yellow edges to a handful of her leaves. pH droped a bit today down to 5.6 but has been stable at about 6.4 previously. Photos from the last few days show this problem has been creeping for a couple of days. Any ideas?

What are these on my leaves?
I was told perfect leaves are impossible to get, but this has to be something right? I had some nutrient burn from one week that was quickly stopped at least as far as the tips of leaves. Is this nutrient burn? a nutrient lockout of is it normal for flower? Im hoping this is norm

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?
