Th Critical Kush

She is definitely hungry for nitrogen. You can tell from the way the leaves are yellowing from the bottom up. I would give her a feeding of 4ml/l of the fish mix and that should give her a boost. Also be careful misting your plants. Especially with the lights on. The water drops can magnify the light and burn them easily. Good luck flowering her.

I see. Turning full yellow with 3-4 weeks to go. Let's talk about it👍 Right off the hop, the buds look great and are forming, bulking up nicely and I don't see any nutrient burns or singed tips. Immediately leads me to believe that this is just a deficiency, and thought it's wide spread, I actually don't think your plant looks bad or unhealthy. The yellowing leaves I believe are a Nitrogen deficiency. The way it covers the whole leaf nice and evenly like that. Our plants don't take too much nitrogen at this time of flower, but it is still essential and she is lacking in this territory. Along with the nitro, I would also suggest a full and balanced feeding of whatever mid-late bloom schedule you're choosing to use. Long and short of it: Up your N and either hold or slowly increase your P/K/Cal and Mag along side your next feeds. I advise to go very slow with the Nitrogen as we don't want to swing too far the other way and catch a toxicity or a different deficiency. I feel a couple consecutive feeds like this (and a flush through @ your discretion) will bring your foliage back to full health. There really hasn't been much of any damage at all, just coloration. I feel you have nothing to worry about at all, just a few tweaks to your feeding schedule. I hope this somewhat answered your question. If you want to speak more on this, drop me a line in PM and we can talk more about feedings and possible doses to adjust in order to bring her color back to full, beautiful green. Cheers my friend and good luck until we speak again. 😉👍
