This is a sign of calcium deficiency, but I see that your leaf looks pretty dark green so this could be the problem. If you add too much nutrients it can lock out other nutrients causing these issues. I suspect this is your problem. The other thing that could be causing this is too much pH fluctuation or your pH running out of range. In soil I shoot for a pH of 6.5 and in hydro I shoot for a pH of 6.0. So check your pH and if it is in range then I would back off the nutrients a little and it should stop the problem from spreading. Good luck!

Most likely Calcium or Ph related. But half a leaf does not a very good diagnoses make. Although it is clear and easy to see. Foliar feed Cal-mag to fix the leaves, or leave them they won't fix themselves. But make sure too add more cal-mag to the mix so that it doesn't spread. Or if you are fairly certain you have enough Calcium, Ph could be another culprit.

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.

The clone has bad leaves. Need helpTell 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.

Leaves Turning Yellow - RQS Watermelon AutoHi 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..

Yellow leaf tipsHello,
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.
