little bit sick

[stueee12]

Hi there everyone

This year I decided to utilize the fact that my back garden has the sun on it from the minute it comes over the house early in the morning till it goes down. I planted 4 autoflowers due to it not being to dark out there at night and my last attempt given me by a friend revegging. 3 are from royal queen seeds and another free one from the seed bank. They have been grown in light mix and I have bio grow and bloom. I have fed them 3 times starting at .25ml/L I'm now on 1ml/L the rain has stopped me giving them more incase of over watering. The new growth is now starting to yellow. I was just wondering if you guys could help me out with what is wrong and how to fix Thanks in advance. The last pic is the freebie I Didnt think it was an auto cos its massive compared with the others but it looks to be begining flowering too.

Are you feed grow bio grow and if so what are the NPK numbers.They don;t look that bad but a little higher dose of nutes along with cal/mag might help.

Thanks, yeah bio grow the ratio is 4 3 6. I have wanted to feed them a bit more but the bloody rain! I'll give them a feed tomorrow. There just a couple of days over 4 weeks and starting to show signs of flower so should I mix in a bit of bloom or hold off on that a little longer?
