Critical - Royal Queen Seeds

Not been on in a couple of weeks and had some stressful times. After flushing they perked up but then quickly started showing signs of nutrient deficiencies and I didn't give them a good feed in time. the critical didn't look healthy in that week. Thankfully the following week it perked right up and is now growing like a champ. It's been a few years since I've grown so getting everything dialled in has been a learning curve, also the first time I've used soil and seems to have been the most difficult :/
