fixing nute lockout

The dolomite lime is a good option for raising the pH levels and if it doesn't help then increase the amount by 20% until good results show! You can also try adding baking soda to your solution to increase the pH! A Calcium/Magnesium additive may also help in increasing the pH levels of your solution and soil! Don't forget to water with at least 20-30% runoff and check the runoffs' salinity (EC) and pH levels to determine your soil condition! And what your plant is suffering from is most likely Phosphorous (P) and some light Potassium (K) deficiencies! probably due to the acidic soil/solution so fix that and stay with your current dosage, if the problem persists after fixing the pH then increase your PK additives (usually the bloom/flower fertilizers) Hope this helps! Good luck and happy growing :)
