Forbidden Runtz Auto & Northern Lights A

you could try lowering the light to aorund 50-65cm. Do it about 5cm a day. The temps are a bit low as well that can stunt growth. 19c try to get it up to 22c min 26c ideal. Also the you grew it in a large pot right away. almost 50L The plant may want to grow out and find its surroundings first before putting a lot of top growth on. What do you plan on feeding them once they need some food? also avoid allowing water to stay on the pants leaves under grow lights. it will burn them. Best of Luck

Quantum boards, Samsung diods, osram far reds, meanwell drivers and acceptable price for you. Dimmer is very practical when you veg and flower under same setup. All current lights are really good, those shady days are over a bit ... Good luck !!!

Just went through your diary and this is what the plant should like when using LST, and I've personally grown both strains. You're not going to get that giant main cola since you're using LST but instead, you'll get multiple colas which equal a better yield. I would advise stopping the training once the stretch has completely stopped really no need for it after that.

I'm growing the same NL and I just finished week 15 and it's not done yet. It vegged for 6 weeks as well so I'm guessing yours will take about 15-16 weeks to harvest as well. You can harvest earlier of course but it won't be up to 100% of its potential. I suggest just continue growing it like you are and flush on week 14 or so. Good luck growmie. Breeders' suggested time is just a suggestion but to reach its full potential most strains take longer than that.

Your NL plant is suffering from a general chronic under feeding, and the damage looks like a mix of potassium and calcium deficiencies. The Runtz plant seems fine. All plants have differing needs, what might be good for one may not necessarily be good for another. Feeding the different strains the same nutrients might not work, as has happened in your case. It should have been obvious weeks ago that the Northern Lights plant just wasn't getting enough fertilizers to maintain health, however what you were giving was totally adequate for the Runtz plant. This could have been easily kept in check by giving the NL plant some extra feeding or slightly stronger feeds than the Runtz plant. To fix your NL plant you will have to feed it more than your Runtz plant, a fairly simple procedure. She definitely needs more cal/mag and extra P/K booster. Do this and she should pick up. Giving both plants a dose or two of soluble trace elements (available from any garden center) will also boost health. Giving the NL plant some seaweed tonic/extract will also help it recover faster and boosts its metabolism too. Hope this helps, Organoman.
