Tips burning, brown spots
Anorakstarted grow question 3 years ago
Hello growers! I have White Widow in the 5th week of flowering. Only top leaves are affected, some of them are turning pale yellow. Feeding her with NPK:18-12-18 and Cal-Mag. The brown spots are my biggest concern.
THANK YOU!!

Seems like Excessive nutrient + Light burn(and maybe excessive heat, but it could be due to light exposure), a hard combination that one make the other worse.
Check for light proximity, and if you use fertilizer take a time without, with only water.

It looks like nutrient burn with a slight lock out issue going on. Lock out could be from PH being off so check that and also get the nutrients down. If grown in soil I would “soft flush”.

Leaves tips turning lime greenThe leaves tips on one of them are turning light green/lime.
This one also stretched most out of three in the last 8 days since they started to flower.
The big one is 50cm away from Mars Ts 1000 (150w), smaller ones are 60cm.
I think the light is not to close.
Help appreciated

Do these look healthy? Thoughts? I'm new to hydro/growingI have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

What are these yellow/brown dots and how can I prevent more from developing?Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.

yellow/copper appearance in some leaves after first run off wateringhi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints .
this is only on old leaves so looks like mobile nutrients.
could this be cal-mag issues?
