GG4 Auto / Auto#1 - First grow

Decided that this week ive probably went a bit big on the 3 gal pots after reviewing other grows (Whoops, not the worst problem to have) so I invested in another tent to split the girls up. Im hoping this will improve the air flow later in the grow, well until I decided that it looked a bit sparse and started some 1 gal ladies away. Anyway im a massive idiot and burned the GG4, ive learnt the lesson of monkey see doesnt mean monkey should do. Anyway we'll get into that. Sun 5/6 Got myself drip trays for all the pots, which will be help keep the tents a bit tidier when the watering intensifies. Also picked up a soil moisture/pH meter, from further reading soil pH is going to be important (Foreshadowing here.....) Both GG4/Explorer watered today (Not measured, stupid) as meter suggested soil moisture was low. Fed around where I suspect root mass will be and moistened edges of pots. Ariel/Cindy not fed today as both soil surfaces were moist. Im concerened about little Ariel, but im holding out for here. GG4 = 6CM // Explorer = 3.75CM // Ariel = 1CM // Cindy = 1.5CM Mon 6/6 AM Cindy/Ariel surface sprayed as was dry. GG4/Explorer left untouched as they're moist. PM All plants sprayed until surface moist, warm day today and I struggle keeping the humidity high within the tents so the surface seems to dry rapidly on the seedlings. New tent should arrive tomorrow! Tues 7/6 AM Tent arrived and set up with GG4/Explorer Transfered. This tent has a MarsHydro 100W in. GG4/Explorer fed with 400ML water + 0.15ML Bio-Grow, having reviewed many other auto grows it seems that they're giving growth nutes early doors. I must be doing something wrong here so planning to slowly introduce Bio-Grow. Ariel/Cindy left alone as theyre looking ok. Well as ok as Ariel can look :S PM GG4 leaves are showing slight yellowing (That foreshadowing we we're on about), shit. Wonder if it could be light burn from the new light? Ive upped the light distance and will monitor. Wed 8/6 GG4 further development of yellowing with some browning now showing. Surely if it was light stress I would have seen a small improvement, but perhaps im being too hasty. Planning on waiting another day and seeing where we see any improvement. No feed for GG4/Explorer Spray feed for Cindy/Ariel Thurs 9/6 GG4/Explorer fed 150ML of just water as both are looking dry and feeling light to lift. Still no improvement on yellowing/browning of leaves however new growth is progressing so im not too concerned? Will need to ask wiser heads for advice relating to this. Further research is leading me to think ive nute burned it. MY water pH is coming out around 7.1 as well which wont be helping. pH down ordered as im sure ill need it anyway. Ariel seems to be recovering slightly now all be it pale on new growth, will monitor this little one further and see what happens. More seeds ordered so if shes not going to grow big I might slot her in a 1 gal and stick something different in the 3 gal. Thoughts? Fri 10/6 GG4 well and truely upset with me however only 2 leaves showing significant issues, however this is starting to spread. Posted a question and answers are reflecting that I have A) Too high pH water B) Have fed nutes far too early. Live and learn. Advice seems to show that around 6.2 will be a good range to shoot for. pH down didnt arrive today so will hold fire on any further feedings which works nice as all are moist enough. Have LST'd the GG4. Sat 11/6 Officially 2 weeks today. Whilst im disappointed in myself with the GG4 I suppose its normal to make mistake in something new so trying to not be too hard on myself. Ive got pH down and have fed both GG4(350ml)/Explorer(150) respectively with 6.2pH water. Hopefully this will be the start of the turn around a learning moment within a new hobby. I really appreciate the kind words from those that have already posted and of course any further advice would be massively appreciated.
