First time indoor grow: Need help friends!

If it’s good enough for a top grower then it’s good enough for this novice lol thank u for the help
Hahaha. I am by no means a top grower. Just have some experience and a lot of reading under my belt. Thank you though and good luck! I recommend starting a journal and this will make it easier for everyone to help out in the future.
 
Hi fellow growers,

I am posting an update with my new lamp and ph levels. Here is the lamp: Cree CXB3590 3500K 100W.My current temperatures have risen already to 21.5-22.5 C from the lamp, humidity levels fluctuate from 70-80% depending on when my fan is on.
For the nutrients Top coco A+B from Top crop and Bac Ph Down since my tap water ph is 7. I have given a watering today with a tiny bit of nutrients and with a Ph level of 5.78. The runoff from the bottom of the pot was at a Ph level of 6.15.
I was wondering if I should purchase Cal mag or any other product.
Thanks for the replies, any tips and comments are always appreciated.

Cheers bud, I appreciate your help. My guess for the tent size is what you said 2x2x4. I have looked into Mars lights and COB leds. I have decided to purchase a COB, I will test it out and see how it goes. For nutes and making the ph more acidic, do you have any more suggestions apart the cal mag?
As said, most use pH up or Down to adjust pH. You can also use Lemon Juice to lower pH & Baking Soda to raise pH.
 
Any recommendations on what I could do to bring them up? What heating methods would be the most affordable? @CO Finest
I have a small tent so I doubt it would take a lot to go up 5 degrees
I am waiting for my LED cob to come in and see how it'll go. Thanks for the replies and help
I think the COB light will probably raise your tent temp the 5 degrees. I'd wait and see before adjusting things. You might have to adjust back if you do.
 
Photos no nutes yet. Was gonna start nutes at 4 weeks.watered 3 days ago
No, No, No ! Never feed just water to plants in Coco. Treat it the same as Hydro. Nutes every time, every day.
Do you have Coco nutes ? Some are pH perfect (really not perfect, but pretty close); so you could feed & not worry too much till your pen gets here.
Keep in mind those cheapo $10 - $15 pens aren't worth a shit. I tested my nutes with 3 different cheapos and got 3 different pH readings that were quite different. That was the end of cheapos for me. Just bought a BlueLab the other day.

Don't let those drops of water stay on the leaves during lights on. You will get leaf damage & think it's something else. Plants drink from the underside of the leaves. Not the top.
 
But lemon juice coukd kill good bacteria, so small Amounts is what ive read, correct me if im wrong??? And delete if nonsense lol
I've never heard that; but maybe. I've used Lemon Juice for a few days at a time when I ran out of pH down. But just till payday when I bought a new bottle. Never had a plant issue from using it. I'll have to research to find out if it effects it or not. I actually got that info from one of my grow magazines. Now to find the magazine to see what it says.
 
Thanks @Buds Buddy , I have Top coco A & B nutrients by the company Top Crop, ph of nutes Is 6,5. Together with PH- which uses nitric acid. I will buy Calmag for the coco. About the temperature it is not really going higher then 22. I have had the new light on overnight and same temps. I was thinking of getting another lamp, due to purchasing some more fans to have ventilation inside the grow tent.
