Maybe over watering. Only water when soil gets dry.

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..

Wilting and yellowing leaves after vinegar water solution I sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳

Living soil and rain water problem Has using rain water killed my living soil? Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients. So basically is my living soil now just soil or is the microbial life still there?

Leaf browning, yellowing curl one day change.Over night my plant went from looking good with maybe a calcium deficiency to curled leaves looking very soft and drooping. I sprayed with insecticidal soap, but in the past no harm. It is growing outdoors, 30c 60% humidity. Any help appreciated. I sprayed with kelp today.

Leaves' apex yellow/white First grow here. This is an auto strain 20/4. pH is on point, I'm using growing nutes once a week (I water around twice a week). Only the young leaves have this. What is the cause according to you guys ? Is it a serious problem ? Thank you all :)

Hi all! I was checking on my plants and noticed one of them is showing yellow/brown spots in some the top leaves, only showing on 1 plant but I’m nervous it’s leaf septoria?? The plant is in week 10 and is my last pic on week 10 diary. Does anyone know what this could be? :)

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.

Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?
