Early Flower Symptom

Sox21
Sox21started grow question 4 years ago
I'm getting worried about this plant as it goes into flower. I don't know what it needs to keep this yellow and Browning from spreading. I fear I might lose a plant that started Browning similarly to this when it started flowering too. I use the "GO Box" kit. What does it need?

Looks like potassium (K) deficiency, quite normal at this point. It needs flower nutes.

Heya Sox21! Looks like its looking for some more potassium! Potassium deficiencies start with yellowing and burned edges/leaves. It can sometimes turn them white almost which I almost see in the one picture on the leaf edges. You also want to make sure pH is in the correct range. In soil, potassium is best absorbed by the roots in the 6.0 – 7.0 pH range. In hydro or coco coir, potassium is best absorbed by the roots in the 5.5 – 6.5 pH range. Add in some more nutrients, specifically with some potassium and keep an eye on the recovery. Cheers and good luck!

Looks like you took away its nitrogen too quick. It still needs it for pre-flower and probably the first week after that. I'm guessing you just switched to bloom nutes too early. Easy fix though! Make sure she is getting enough calmag as well and she should be fine.
