Like robert said Use some pk boost start 1/4tsp/gal. Also smell your soil should not be rotten which can kill roots uptake if u use too much organics. Humic acids may help too.

Defo not light burn just looked at your distance. That light isn't strong enough to cause light burn that bad from that far away pal. 100% potassium deficiency.

Pretty easy one. In your situation everyone missed your bulking in flowering. Which has a high demand for potassium, and phosphorus. Using small potters at that. I would measure some run off water for ph. When I have done root bound in small containers the ph likes to start drifting.

You're missing the grow big in your feed. The fox farms trio requires all 3 bottles for a complete nutrient

Slight Yellowing on tips of new-growth? (VEG)Why am I getting slight yellowing on the ends of new-growth leaves? It's affecting every plant. The only clue I have is that it might(?) be related to very cold nights because of my re-vegged photoperiod showing purpling on the edges of its leaves. Any ideas?Week 5

Issues after first sledgehammer flush, 4 weeksHey guys and gals, on week 4 of this indoor, hydro grow and I just hit this plant 5 days ago with fox farms sledgehammer for its first flush. Before this, the plant was growing very well. Is this due to the flush? Should I flush in tap water before next feed? Thx for the help ^^Leaves. Color - Yellow

Upper leaves turning yellow - Day 28 of flowering - Cinderella Jack AutoOnly "half" of the plant is doing that. I don't think its a pH problem, the other plants are receiving the same source/quantity of water/nutes. My guess is the buds that are receiving more light are "maturing" quickly and the plant is sucking the leaves close to them.

(Mimosa auto in coco) Yellowing tips on new growthThe top of the plant (new growth) is showing some unhealthy signs.
The tips of the leaves are yellow and there are lighter green stripes on the leaves themselves.
I googled and the signs match to a number of deficiencies, but i lack the experience to diagnose correctly. Plz help3y ago

Burnt tips and yellowing leavesAbout two week ago, lower leaves started yellowing, and I saw burn leave tips, so I suspected nutrient burn. I only watered with tap 6.5 pHed water since, but the burnt tips and yellowing are getting worse continuously. At least 3 largest lower leaves died off over the period.6y ago
