So this is our third grow. We’ve got three Strawberry Pie and one Grapefruit from FastBuds, two of which have been up now for nearly four weeks (two more Pies popped later).
We initially had some burning of leaves after putting our new HLG 260 rspec up, and I thought that the girls had recovered okay (after losing one completely). Then we started seeing something on the leaves that came out after the lighting error.
Question #1 What’s the diagnosis? It looks like cal mag deficiency from what I’ve been able to learn. I’ve been adding 1/4 strength Fox Farms Cal-Mag for the last three waterings and I’ve not seen any new problems on the newer leaves. They’re in Happy Frog, btw. Do we continue adding the Cal-Mag? For the forseeable future?
Also, I know that autos can be a little more delicate than photos. Since our tent is only 2x3, we don’t have room for the four 5-gallon bags of autos along with the two photos (ILGM’s Gorilla Glue & Girl Scout Cookies Extreme, seen in back being quite robust with no signs of problems). So the idea is to let the autos veg outside while the weather is perfect (low 80’s) and bring them in early evening for more light just outside the tent, but inside the tent flap just out of frame above.
Has anyone else done this kind of mixed light back and forth with autos? Will this shuttling in and out of the house every day stress them out and make them less productive? Or do they need just one consistent home?
Thanks to all who respond!
