I am growing autoflowers in peat moss vermiculite mix. They started in organc seed mix and I added peat moss later on. All 5 are in 2 gallon smart pots and have been fed flora series at a PH of 6.3-6.5. Run off seems very low in the .5 range. Looking at the pictures, can someone advise on what to do to help them grow better. Light schedule is 20/4 and temps range from 75-85. There are 2 300W led grow lights and they are 3 weeks old
