3rd grow

What’s up everybody! What are your thoughts on this grow? I bought these seeds from Tony Greenhand’s site. 2 are from a pack of variety seeds so I don’t know what they are. The other 2 are fruit cup from the same seller. I read on other grow diaries that the deficiencies I’m seeing here usually are due to over watering. I water these plants about every other day usually. Every so often in between I’ll give them a good watering to the point of dripping. I’ve given them nutrients about 3 times since I started growing them. I put the seeds into root riot cubes on 6/5, they sprouted on 6/8. I’ve had them in small pots since until I transferred them into fabric pots on 7/20. I kept one in the plastic pot just to see the difference in growth rate. What do I need to do?Water less? Up nutrients? For watering I use a brita and when I test it’s usually pretty close to 6.5. I’ll add in ph down usually and then water so I think it’s uptaking what it needs just fine but I’ve never tested the dirts ph. For these 4 plants I’m using fox farms ocean forest soil which I’ve read runs hot but again I’ve barely given them any nutrients. I’d also like to know for how much longer I should let it Veg, I read in a grow book that they should be allowed to Veg for 60 days which is what I planned on. I also read that they’ll grow 2-3 times their size while flowering, I honestly don’t remember that kind of growth from my first two but then again I kinda fucked up on both in different areas. Tell me where I’m messing up this time. In the first 4 weeks the poor plant suffered kind of a lot because the tent was getting super hot since I didn’t have an in-line fan in there so it reached temps up to 103 and humidity was at a low 30% and I don’t even know for how long since I was at work most of the times. I’ve since built these little stands under my pots to allow them to drip into the pans and I just let the heat from the lights evaporate the water to create the humidity I need. Since I’ve seen a good growth while the hygrometer reads a consistent 40 and up to 55% humidity at times. I topped all 4 plants on 7/1, I trimmed 2 about a week later. Based off the YouTube video I saw the guy said trim off the branches that have red because those are the ones that have matured so I did that. Any help would be appreciated.
