I think this is problem with coco buffer. Try to use more cal-mag and change your nutrient solution. Lower potassium, raise cal-mag.
Problems with coco pH - always about wrong watering and wrong composition of the nutrient solution.
p.s 5.8 pH its not bad for vegetation.

You are spot on. Coco range 5.5 to 6.5. You couldn't be any better. Your run off is smack bang in the sweat spot at 5.8 and 5.9

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..

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.
