Hi all,
First time posting, really appreciate any advice you kind folk might be able to offer
I've been growing a white widow auto from ILGM (pictured), under 500W UFO LED lamp, using Hy-Gen coco nutes with Canna coir. It's planted in a 16L pot, about 80% full of medium
Growth is in week 7, about 2 weeks since flowers appeared. I've been feeding bloom nutes exclusively since the start of week 7 (as per Hy-Gen's instructions). Also regularly feeding Mega Crown bud booster and terpene juice, in doses per manufacturer instructions
I have been watering whenever the subsurface soil is not-quite-dry, with a dose of plain Ph'd water between feedings wherever they've been frequent. The root system under the plant seems to be very strong and dense
The bud formation was quite slow, but over the past few days, it's accelerated, with each of the heads seeming to fill in visibly, a bit each day. New leaves are also appearing on the heads each day
However, the discoloration you can see in the pics has really taken hold over the last day or two. It appears to be N-deficiency, from everything I've read (fan leaves yellow and falling off, discoloration "travelling" up the plant), but it occurred only *after* I gave the plant a good dose of bloom nutes - so there should have been an increased concentration of N in the roots, rather than decreased). I guess it would be using a lot of N to produce new bud sites on the branches - and probably drawing it from elsewhere on the plant, so maybe I just need to add more (?), but I don't want to risk overfeeding. Doesn't seem to be a lockout issue as Ph is within acceptable range and the acceptable range for N is really broad (not that I can really measure it properly, the plant hasn't produced any runoff for several weeks - no matter how much water I add). In case it is lockout, I've also looked into foliar feeding, but I'm unsure as to whether I should be doing that so far into flowering
There is another plant from the same type of seed sitting next to this one in the grow room. It's a week behind this one as it was sewn at the same time, but the seed was slower to germinate. That one is exhibiting the same symptoms, but nowhere near as pronounced
I'm sure experienced growers will have picked up a lot of rookie errors in the above description. This is my first grow, so it's a steep learning curve!
I'm also not sure whether I should prune the lower branches. Best practice seems to suggest I'd lop about half of them (any below 50% of max height), but I've read many posts (including from Bergman) cautioning against pruning autos in any way. If anyone can provide clarity on that also, it would be much appreciated!
I should also add that humidity has been (sporadically) very high the last couple of weeks due to heavy rain. The baseline level is ~50%, but I've seen the meter up as high as 80%. I have ordered a dehumidifier online with express delivery
Please let me know any tips you might have for a stronger harvest
Thank you!
