W3tWeed I'n quite a few weeks in and up until now everything has been going great. at the start of the week I noticed what appeared to be a Calcium Deficiency, I Upped my PH to 6.3 from about 6.1 it seems to have stopped. now the tips of all my leaves are slightly burnt. Any help would be appreciated.
Those spots to Me look like calcium but more apparent is they look a little over N and too higher ec, I would dial back the ec or at least the base ec with most of the nitrogen in.
I would do this and see if the brown spots get worse, if so add cal mag but still back off the base nutes with most of the N in. Happy growing buddy👍
