Hi what deficiency could it be?

Hi, the EC was a bit high. I water with 1400 and the run off was 2500. I think an excess of Phosphorus made the issue. I used deionizated water to get it to 1300. I can't do a full flush right now . Would you think there will be a problem. @dutchdoobie if I follow the scheduled ratio the amount EC will be very much high. I asked to a better ratio proportion directly to them and in using that ratio. I think the vermiculite kind retain much of the nutrients and release then slowly so the amount of nutrients can be lower

High deepsheeba, When I just started to grow I liked to use the same GHE nutrients and followed their feeding schedule exactly like how they advice. I have never had a deficiency exept for 1 time and it was because my pH was too high. So I would do a good flush with pH 6 (it will raise slightly to around 6.2 - 6.3). Then give nutrients like you did before and they will reward you with big, fat buds!!! 😋

I would agree with Growinggrannie that you have a ph problem locking out some nutrients, possibly copper, magnesium, maybe potassium. Lower your ph between 6 and 6.2. One other thing that popped into my mind was possible light stress.

It's one of the micronutrients - sulphur? zinc? manganese? But is most likely caused by your pH not allowing the plant to absorb these even though they're in your nutes... I would drop the pH to 6.0-6.2 and see how she does... Even a few decimal points of pH value can have a big impact on the health of your grow. If you don't have a good pH pen, I'd suggest investing in one as that is an important tool for any grower to have! Good luck
