Lizzi - RQS Special Queen AUTO

Been a while since i last updated. and alot has changed. Image 1 - Trained Lizzi This image is my first image in my new grow tent, under my Spider Farmer SF1000D Grow light. turns out home made grow lights work a little, but not enough as the difference in growth rate is second to none 2 - Lizzi Bud This is my first auto plant. after a slow start she finally started catching up. Under my Home made Grow Light she was receiving about 400 PPFD. at a distance of about 3 inches. this was no good. Since changing to this SF1000D light, its been about 3 weeks. and since then. she popped these little white hairs. i got excited as like i said this was my first auto. so will be my first time smoking what i know to be an auto. 3-4-5-6 = Lizzi Leaf Discoloration in the 2 weeks, some changes have happened. i had an issue with fungus gnats. they were everywhere. so done some research and made a potion from garlic powder, lemon and peppermint extract oil, and mild chilli powder and water, good shake, and a very light spray outdoors, over the plants. this booted those suckers out pretty fast and i move into the shed. all the flying gnats were left outside. i figured i wanted a barrier to prevent this happening again. so i placed a 3cm layer of sharp sand on top on top of the soil. now they cant get in or out. after a few days. i did the unthinkable. sprayed a can of raid fly and wasp killer in the tent. and its eradicated every living thing in the tent. great job. the leaves have started changing in the last week, and im confused. on one hand we have burnt tips. so im thinking to many nutes. but we also have browning on the edges of leaves. so its confusing me The Soil is a - Westland, Multi purpose Compost, with added john innes. is a nice quality soil. i have grown lots of veg and tomatoes and a tonne of chillis, and so on in the same soil. its good soil and i wont hear a bad word said about it ha ha. in any event, it has good drainage and built in nutes, (hopfully organic). the bag says there is nutrients a plenty for at least 6 weeks. so by this point i could be running low. i was using the Royal Queen Seeds Easy Grow Fertilizer tablets at a slightly weaker dilution. but have ran out and need more as i like the ease of the tablets. would like to know what people think
