How old is she? First things I'd check are the soil and then the nutrients. The soil looks like it could do with better aeration but to me she looks hungry.

Yellow leaf tips
Hello, I think I have a slight over-fertilisation. Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

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..

Leaves have developed "claws" at the tips that bend downwards
My leaves have developed "claws" at the tips that bend downwards. I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate) Now my question to the professionals: what can I do to fix the problem? Green greetings! 👽

Natural or Problem?
Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
