Seedsman Lemon (First Grow)

johnny003 This pretty lady is recovering from a nute burn that I have done around a week ago. So for context, I put fertilizer although it was not needed (I figure out too late). I thought that the light green part of the new growth was actually a nitrogen deficiency and I put 10;0;0 fertilizer once. Then, as soon as I saw the nute burn (the tips were turning brown to every leaf), after reading on solutions, I decided that a flush was needed. Therefore, I flushed the plant with 3l of ph balanced water. The runoff at the beginning had a ph < 5 which was obviously too low. As I continued flushing, the ph went up to > 6. Therefore, I decided it was enough. After then, I haven't watered her for around 5 days and the soil still seems wet. Now she seems to have recovered and is in her preflower stage. I expect the stretch very soon (this week?). The thing that concerns me is that her leaves are kind of droopy - especially the lower ones.

johnny003 Did some light defoliation every other day. I water every second to third day with nutes.

johnny003 Started having some nutrient deficiency probably. I'm thinking it's magnesium/calcium deficiency. Can anyone help?

johnny003 Plant is doing well but some nitrogen deficiency probably showed? I upped the fish mix by 0.5ml but the ph also showed to be low... going to feed with 8ph water to increase it.
