I always add calmag to the nutrient mix . I have soft water in my area at 0.1 EC . I up that too 0.4 EC with calmag . Then add base nutes on top of that . Doubt you need to flush . Just add some to your nutrient mix .

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..

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.
