Phosphate, Potassium, and nitrogen deficiency can also cause the tips to look burnt. Although without knowing OP feeding we don't know anything.only asking, do the tip not look nute burnt tho?
Agree with the yellowing, last feeding (2 days before the pix) a concoction of Shultz 10-15-10 half strength MG 8-6-7 half strength and Thrive vitamin B with 1-1-1 at half strength was fed to them. If they are starving, why do they show burnt tips?ph is fine. 20-10-20 would be a better ratio. Not getting enough nitrogen for my tastes and would explain the yellowing. On my last grow I mixed my grow nutes with my bloom nutes to get the leaves green. This grow, just keeping my Nitrogen at the proper ratio to insure health happy plants to harvest.
Did you see the size of that thumb holding the lighter, definitely had a tsp/gallon, lmaoA pinch of Epsom is not even worth it , takes at least a teaspoon to a gallon .
They are indoors, but point taken about the leaves showing on older pre-existing conditionOutdoor growing has the highest light intensity, hard to beat the sun. Leaf tips are the most sensitive part of the leaf and the first to show signs of problems. If the problem is fixed, the leafs will still show the damage, forever.
Best guess, probably too much sun on a day the plant was dry or had just been fed and the tip burn presented itself. Look at new growth from this point forward for corrections. The plant is focused on bud production not leaf, so you should be able to coast to harvest as long as the new leaves are showing improvement.
does someone live in that tent mate?can u spot anything wrong, or know why half a leaf gone yellow?
Just a general health check ha.
