Lemon Haze from late Hermie

This was their first week of flowering with a dark period from 8am to 8pm. This was so that to compensate for the cold nights we are having out here with temps hitting 16-18C Mon 19/07 Day 1 flowering and not much to do except for a few gentle touches. Tue 20/07 The plastic pots with LH1, LH2 and LH3 were still heavy so only the LHB2#1 to LHB2#5 got watering with PH 6.8 water. Wed 21/07 I gave them all a splash of water as I was leaving town till Friday evening and didn't want to come back to a overly thirsty plants Thu 22/07 I was away Fri 23/07 I gave them a good looking over when I got back and took measurements for height before feeding them 1 tr of water ph of 6.8 with epsom salts LH1: 15" LH2: 13" LH3: 13" LHB2#1: 14" LHB2#2: 17" LHB2#3: 16.5" LHB2#4: 16.5" LHB2#5: 14.5" Extra one: 14.5" I also noticed a calmag deficiency combined with some nute/burn lockout. I do not have the space to carry out a flush and will look up other solutions. I have proactively bought some synthetic PotPhos liquid (NPK 0:50:30) as a remedy if I am unable to correct this organically. The issue was only on LHB2#2, LHB2#3 and LHB2#5 - since everything is uniform in the tent, I am left a little confused. Sat 24/07 I have prepared a top dressing with 40% cocopeat/perlite mix, 10% humate powder, 10% bonemeal, 20% organic soil improver and 20% worm castings. I was to add this and water them today but want to see how long it takes for them to dry out the pots. I suspect the nute burn could also be from them sucking up the leftover salts in the soil when thirsty. Sun 25/07 I vowed to read up about VPD as I am currently running the exhaust on full to acquire RH below 50%. I have skipped both watering and top dressing and pushed them for Week 2 of flowering that will begin Mon 26/07. I also intend to defoliate, top dress and water them on Monday and after which I intend to only focus on watering her for a week to to days. Here's to another easy sailing week ahead.
