I have noticed leaves drying out on my plant, they are still green though so I left them on. The edges dried out and crumble away if touched but there is no discoloration. At first I thought it was only the leaves that were close to the lights but it's not. One leaf became pretty much lifeless but once again remained green. I took it off anyway cuz it's pissing me off. other leaves on this plant are fine (main sunleaves that come off the main stem) but the leaves attached to the bud branches are in trouble. Anyone know of a common problem that occurs in flowering to these leaves? No discoloration just drying rough looking leaves. The leaf is green but there are some darker blemishes that if i look on the underside of the leaf I can see. Not all over though.
How far into flower are they? What are you fertilizing it with and how often? What kind of light(s) you using? What is the temp in the room? Is this soil or hydro? Do you have pictures?
you growing with soil or hydro? need more information SOIL: What STRAIN are you growing? What was the establishing technique? (seed or clone?) What is the age of your plants? What PHASE (seedling, vegetative or flower) are the plants in? What Technique are you using? (SOG, SCROG etc) What size pots are you using? (Include how many subjects to pot) What substrate/medium are you using? (percentage of perlite, vermiculite...etc?) What Nutrient's are you using? *Knowing the brand is very helpful* What is the TDS/EC/PPM of your nutrients used? What is the pH of the "RUN-OFF"? What method of pH test was administered? When was your last water? When was your last feeding? What size bulb are you using? What is the distance to the canopy? What is your RH Factor? (Relative Humidity) What is the canopy temperature? What is the Day/Night Temp? (Include fluctuation range) What is the current Air Flow? (cfm etc.) Is the fan blowing directly at plants? Is the grow substrate constantly wet or moist? Is your water HARD or SOFT? Has plant been recently pruned, cloned or pinched? Have any pest chemicals been used? If so what and when? Are plant's infected with pest's?
