Old leaf showing an old Cal Mag deficiency I think. (EDIT: probably just PH fluctuations actually.) Rest of plant looks god apart from some little bug eating my new leaves. Applying Pyrethrum weekly to manage. (EDIT: apply just before dark period) She gets Cal Mag every other feed and about 1100ppm bloom nutrients. Very very slight nute burn from last feed so won't increase until she doesn't burn at 1100ppm. Upgraded pH meter to a properly good one which might help a bit too. pH out still mid 5s which isn't ideal but she seems to be healthy. I ordered another 300w (135w draw) LED today (10/18) to help fatten these nugs up. F19 - decided to take it easy on the nutrients. Feeding about a gram per litre (forgetting the PPMs for a while).
Day 6 gave it some seedling nutes only 170ppm to ease her into it. She's also been ramped up to 20/4 from 18/6 today. Mars Hydro 300W (drawing 135W) at about 24". 170ppm in and abour 350ppm out. 6.5pH in and 6.3pH out.
Looking good! Anything above 20c is fine looks indicate by the wide shape of the leaves they can usually grow fine above 16c. Trust me from experience where I live it gets cold 😨
hi man!
You say this is your first grow...you want try scrog with one plant in first time grow? I read on your profile, scrog like method of growing......really?
