What causes these spots?
Scrubbyjimbobanswered grow question 20 days ago
I think you got more than one thing going on with this plant. Definitely a rootzone problem, either overwatering or pH. Address this first before playing with your nutes, they may be linked.

Looks like the PH fluxed a bit to me, but I agree with other in that this plant is overwatered and it looks like its been this way for some times.
Adopt some better watering standards, its hard to understand but if you know you like to poor lots of water in then amending with more perlite might be a better option as it makes it hard to over water, granted you will need to water more often when the plants are bigger or setup an auto watering system and drain tray.
As for PH, let your solution sit out fully mixed for 12 hrs and test its PH, see if it is stable it might have drifted a bit. With soil its good to aim for 6.2-6.5 for PH range in the soil. It can also hold onto a lot of nutrients so be carefull of overfeeding it as it does not flush well.
Good Luck!

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.

They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶

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.

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

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..
