I have used the FF lineup with nice results. It's viable for growing but I think it's considered more of a starter to mid range lineup rather than advanced like this forum typicaly talks about. As mentioned by another post on FF you do need to add Cal/Mg.
I think typical flowering time for NL is 50-55 days so if you are only on day 30ish you will see the majority of weight added in the last 2 weeks. What kind of lighting and how far away are the lights?
For one plant it may be but not recommended. I have 2 TaoT 240W and they are awesome for veg but need mucho supplemental help during flowering, even something simple like adding a 2' 4bulb T5 w/ 3000k bulbs would be enough addition to boost it up in flower.
I use the exact same brand blackstrap you bought with great results. I use 1/2 tbsp all the way to finish every other water only feeding. Brings PH way down to make sure to adjust accordingly.
I had (2) 240W LED and a 324W T5 in a 5'x5' and had great results. You would have no heat issues with the (4) 180 LED's but obviously an exhaust is a requirement to get that stale air moved out. After many many many hours of LED research I would actually recommend something similar to what I...
Hang until you can snap the branch (~68°RH), throw a 62° Boveda in the jar and in 2 weeks you have priemo cured bud. Other than opening the jars once every 48 hours to move the nugs around to avoid moisture pockets in the jar it really is that easy.
I have 2 pointers. Def make sure to give it a bigger pot(numbers below from my 300W LED grow on CD4), and prepare for a ~72 flowering time. :blsmoke:
