That looks like spider mites. Check the undersides of leaves for them.

First time using Coco (Canna Prof), since seedlings the leaves are deformed and exhibit over-watering symptoms. In 3.5L pots with white healthy roots showing from below. Water (with nutrients) every 2-3 days. Could someone suggest where my problem focus should be?

Maybe someone can tell me if I should or can defoliate The BlueDream No 1&2 Cause the leaves cover a lot & each Day the girls grow more & it gets more difficult to LST or bent the leaves somewhere & idk what’s going on with the BlueDream No.3 I did some research & I thought it might be CalMag deficiency so I add 1,5 ml GHE CalMag to 1L water but the problem with the leaves is still there ( see pic BlueDream No.3 ) I’ll be thankful for any advice & help !!

Looking at the picture of the leaf does anyone know what the problem could be? I was thinking maybe light burn? I am growing in Fox Farm Ocean Forest and yet to give any nutes. I transplanted a week ago to fresh soil.

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

I'm using a coco mix with advanced nutrients organic. I water 1l everyday with little to know runoff.The new growth is a lighter green and the leaves are thin. Is this some sort of deffinency or toxicity? I recently just flushed and stared giving half nutes.

Is it normal for new growth 10 days into flowering to be lightening in colour? I am new and noticing that it is fairly lighter than previous veg growth before as my nutrient needs and feed has changed. Just want to be safe! Thx 😄

I don't have a PH meter, just some test strips. Can anyone recommend an inexpensive meter I can get in the UK? There's a bit of yellowing on some leaves (see my diary entry on week 8) Buds seem to be developing a bit slow Should I switch from 24 hr to 20/4 or 18/6 ?

So, my other plants have surpassed this OG, unfortunately, a week younger, too. I took pictures of the PH test Do you think that was the problem? (I personal so I don't water for the first 3 weeks, lol, otherwise the above happens.)

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

I have a deficiency. Can you please check out my pics and give your advice? I thinks its a Magnesium deficiency, am I correct? Increase CalMag? Flush with extra water? Any tips would be helpful.
