I would continue with the Gaia Green and plenty of worm castings too.
Proper and natural worm castings can not burn, so heap it on and in future, use it all through your grow, your plants will love you for doing so!
Looking at your pictures, you probably have another 4-8 weeks, so don't stop feeding too soon.
The quoted 8-10 weeks is just a guide and not really applicable to the real world. There are too many variables to make the 8-10 week suggested timeframe achievable - there is a huge difference between hydro with 2000 watt HID lights and a person growing in a cupboard with cheap soil and a cheap blurple light to make these figures realistic for everyone growing that particular strain.
Hope this helps,.........
