Yes It has been a tough grow for a lot of in ground growers so it seems. How old are your plants and are the photos? Were they seeds or clones? Just curious about that seed clone part. OK when I plant in ground i dig my hole out and back fill with soil that i create in a large tote that stays sealed. I mix it with bat guano, old used potting soil which is coco peat, perilite, black gold organic bag soil and i make teas. Bat guano, fish emusion and molasess. Yes i do feed my inground plants if they appear to need it. Some strains are just lighter green not as dark green as they grow. I have 2 mama mia that are lighter green than say my white widow or kushes and cookie varity. I still feed them same amounts of guano teas as the others they just aren't dark green. Lesson is all plants respond differently to nutes. If your ground is good and soil is mixed with organic mixes lots of it you should be good for couple months. With rain amounts lots gets washed out and i would give teas at least 1x a week with N it all depends on how good you soil is. Yes i do give unsulfured molasses 1tlb spoon per gal to my inground and container plants during last month of flower. I have never given bloom to " in ground" just container. And that is just the way I do it. I am in Oregon and we have below normal temps here should be in mid 80s but it's low 60s windy and overcast most of the month where i'm at. I put mine out a month tooo soon and they just stalled, i have started more auto flower seeds just to make up for a possible crappy outdoor season these will go in 3gal. plastic pots for warmth and faster growth. You just never know how the season is gonna go. I'm hoping mother nature will give us the temps we need this year for mid summer else i'm looking at stuffing a lot of plants in our green house come late sept.
