Lemon SSH (2nd grow)

29.05 Light ~45W (~40DLI) *check in a day or two if that's too much and needs dialing down Day 29 So I got frustrated that my perfect grow went to shit in less than a month and decided to punish LST the short one (Amber), adjusted the ropes on Milky and switched them places. Now Amber is on the left and Milky is on the right. The deficiency looks like Calcium today, rather than Nitrogen but I'd appreciate if somebody could help me out understanding this. There are white spots of dried foliar spray with TA Silicate from two days ago (It was the last time I used it as foliar spray), there are yellow irregular spots looking like Ca def which might be affecting Amber's height, there's pale interveinal stuff going on which might be N def and they also claw their leaf tips (overwatering? but they were droopy dry and I gave them less than 20% of pot's volume)... I thought I have enough Calmag in my hard water but it seems they need more. Last watering was yesterday (day 28) with 2800ml for two, pH 6.4, EC 1.1 (rootjuice + biogrow) Day 30 Oh my, it's progressing. Amber seems to be the one/most affected... Day 31 I thought it might be a pH issue, so I calibrated my pen, but it was less than 0.1 off. Ordered bio-heaven and fish-mix. Day 32 I removed a couple of damaged fan leaves from the bottoms, nothing major, mostly from Amber since she's more sick. Still considering removing those big fat indica fan leaves in the middle but maybe in a couple of days. Watered the girls 2L each with proper Calmag and Biogrow doses. So from 4000ml IN pH6.4 EC1, I got 550ml OUT pH6.9 EC1.5. Which is like 15% (Less than 25% required by the books). Day 33 I think they're slowly bouncing back. Though some of the lower leaves start to look like they need N. I hope yesterday's feed gonna sort it all out. Got me some bioheaven and fishmix for next feed. Too many bottles. Day 34 They both bounced back from drowning and look great. Amber's leaves have some interveinal yellowing, I guess she desperately needs more N. Fish-mix and Bio-heaven to the rescue but only in a couple of days when they dry up. Today was quiet humid, saw some sweat on the leaves yesterday. Removed a couple of leaves that were laying over one another. Day 35 I don't see any new rusty spots which is great. Little Amber desperately needs more N and Milky is asking for more Calmag. I guess I have to do another VEG week to fix them, so tomorrow I plan to give them another feed, remove a couple of big fat leaves so they would be ready for the flip by the end of next week.
