Help To Find Out What Happened To My Plant

[nikson]

hey everyone,
Please who can explain to me what happened to the leaves?


Is it because of too much wind?
Or it is a fertilization / ph problem?

How can I fix it?
There are 2 plants that were damaged when one of them is quite healthy.

There are some very knowledgeable people here who can help you but you should probably give more info on your grow.
-lights? Nutes? Grow medium? Location of leaves on plant? Temps? Humidity? Etc...

Got bugs? Little black specs on the underside of leaves. Look closer and identify specs.

Possibly the beginning of phosphorus (P) deficiency. Ph to 6.0. Give a good flush with bone meal. Give ferts hi in P such as bat guano, steamed bone meal etc. bone meal helps her to absorb P.

I searched with a microscope on the leaves and did not seem to have anything alive

Out side plant? Grow medium?

I am moving your thread to the cannabis infirmary, more appropriate forum for this. :D

I think it’s an outdoor plant?
Could be wind?
Would have to be sustainable wind though.
Looking at browning on top side is causing discolor on bottom of leaf.

i am using 600 W hps + 2 x 100 W led
2X2x2 grow room
2 fans in and out. And 2 fans for airflow. (I turned off one right now because it looks like a wind problem)
coco & perlite 60/40.
now on week 3 of bloom i feed them with this for 4 week from now
sensi bloom a+b 16 ml , big bud 8 ml , silution 0.5 ml , cal mag 4 ml with 5 liter tap water

I do not check ph & etc. I use the fertilizer according to the instructions and add another liter of water to make sure there will be a state of excess. I checked previously and PH in the 5.8-6 area.

The leaves at the bottom look less good but there are also some at the top.
temp around 28-30 Humidity around 40-50.
thanks !

Nute deficiency. Start ph nutes. I would suggest reverse osmosis in the future.

You got a pic of the whole plant? Your humidity seems a bit low for those temps. Also those leaves look pretty dark from what I can tell. Could be your plants are transpiring more than they should and the airflow is leaving burn marks on the edges.

Have you sprayed soap/oil or anything on the leaves during the day or with lights on?

Yes I spray them with cal mag every 5-6 days but uselessly it’s when the light off

I would try to start feeding via the rhizosphere just to be sure. If you spray anything do it right at lights off. Here is an example of sun scalding. It looks very similar.

Ok thank you. I'll stop spraying. Basically I do this because when I was feeding the whole amount of magnesium and calcium through the root the stems were still a bit purple and when I sprayed it disappeared. But if it hits the leaves then I do not mind having a little purple on the stem
