They're hungry. It's probably due to you not using their base nutrient.

They're hungry. The Cow Mag thing was a joke. I would feed them N, P, and K. But my first thoughts are N and P deficiency.

They're flowering and want more. My plants are actually at 5 weeks today too and I just watered them. But mine are hungry too. I'm a lazy ass, and don't top dress enough.

The EC is at 1.8/2.0 I've added about 80ml of shogun terra GROW into my 100L res (for the nitrogen as we thought that's what it was) along with shogun terra BLOOM and rock resinator heavy yields

I'm not a hydro guy, but they look like they're hungry. What is the EC of the original water?

Bushbaby11 said:

Ph is 6.8
Ec run off from 1 of the plants was 3.6

I tried to look up those Shogun nutrients too....crazy how little info they provide, no ingredients, no label pics, no basic NPK info. You are definitely underfeeding, they need more nitrogen fast, just don't overdo it. I would look into the good 2 part dry nutrients in the future. Are you in the UK? Shogun users always seem to be in the UK. I don't think you guys can get Jack's or Megacrop easily, so Athena is probably your best bet, though they are criminally overpriced.

1. DO NOT premix concentrated products. Always add to water.

2. Premix Silicon in 5L of water and pH adjust to approximately 6.5 before adding to your tank/reservoir.

3. To maintain 'Mother' plants for up to 6 –12 months, continue to follow the 'Week 4 Vegetative Growth' schedule.

4. The changeover from 18 to 12 hours varies depending on the plant specie's growth characteristics. The rule of thumb is to change the light period from 18 hours (vegetive growth) to 12 hours (flowering growth) after 2 weeks or after the plants have grown half the distance from the initial plant spacing length.

5. Reduce hours of light if ripening goes too fast. Watch out for increasing Relative Humidity.

6. Recommended pH is between 5.5 - 6.5.

7. During vegetative growth and the first 4 weeks of the flowering growth, the pH will rise as the plants uptake nutrients. Reduce the pH of the nutrient if the pH rises above 6.5 with pH Down.

8. During the second half of the flowering growth, the pH may reduce. Adjust the pH with Shogun Silicon or with pH Up if the pH reduces below 5.5.

Feed the plants 1.8 EC base of Shogun and if PH is within 5.8-6.2 don't mess with it. Those are mineral/synthetic hydro nutrients w/e you wanna call it. All non-organic nutrients like that thrive in a PH range of 5.5-6.2 usually.. I would try to lower the PH and feed as high as 2 EC..

You wanna hit at least 1.8 EC with those nutrients, also they recommend a PH between 5.5-6.2 so with 6.8 PH you're 100% locking out nutrients.
