I was thinking 13 hours light at less intensity to prolong the flower time . To get back to this point would be 6+weeks of veg time then 3 weeks flower and now I'm looking at issues with summer heat in my grow space.

I made a stupid stupid mistake and got the dilution wrong on a hydrogen peroxide spray. Ended up giving them 3% wash at 3weeks into flower. Most of the leaves are curled up and going crispy with all the white pistals turned brown and burnt like light burn!! Is there anything I can do? These...

Okay so raising and dimming the lights aswel as a very heavy water fixed them.

4-5k per plant and any pests will be gone in no time

I used soil dwelling predator mites for mine worked a treat

I'm growing in Coco and the Coco certainly isn't dry. Switched one week ago where all plants were looking good. I have two tents with similar PPFD 650-750 Rh 65-70 Both on the same feed and schedule yet one of my tents is not looking so good! The problem tent is slightly hotter at peak. 19c-...

OH I have also topped all the plants once and then used LST and HST. I let them veg a little too long in the one tent so once I split them up and lowered the nets I HST snapped and pinched the hell of out most of the branches. Ppfd is at 800 in center and 650 on the sides. Once they have...

Feel free to reply and comment. I am staring this journal on the day of switch but I may have a couple of pics from a couple of weeks ago . I have Royal Queen seeds , 4x Honey cream, 3x Special Queen and 2x cheese . Out of 15 seeds I only got the above . Unfortunately 3 Cheese, 2 special queen...

Any my setup is complete

There we go. Just switched. Probably a little too late

Update! I've nearly finished my build. Gone with 400w square 1mx1m to go in my 4ft with a central LEC 315 CMH . Each bar is slightly angled in away from tent walls . Also built 2x 400w bar lights to go in my 5ft

I raised the lights and watered the hell out of them with a slightly lighter mix but full calmag and some hydrogen peroxide. Also raised humidity and they have really perked back up, lush and green! I don't check EC only PH and that was calibrated perfectly

If underwatering is what's causing this. I'm not sure 20% run off daily is ideal for these size plants in 25ltr of Coco.

Ahah, I have been watering when they don't feel too heavy any more , or top layer of soil is dry. Watering everyday gave me some fungus gnat problems in the past. I shall up the watering and lower feed concentration or keep it the same

On the last pics I noticed the lower leaves on the plant didn't seem as bad making me think maybe it was too much light or stress too down

Everything was fine until I lowered the lights a little bit. The two plants in the center getting hit by both lights looked worse to me. I am also getting what looks like rust spots on the leaf. I removed all that I could find. In a 5ft*5ft with 2x 315 CMH . Growing in canna Coco with A+B ...

Thanks for the reply. i will see if i can intake from an area in my house. The air will end up being quite warm though . The fans don't make too much noise its just a compressor style dehumidifier thats really noisy .

I do wonder if I did that it would create a stream of airflow at the very top of my tent , removing head but enabling me to supplement with some co2 at the bottom of the tent

I think I could do one or the other especially in winter. Issue is ect noise so sucking it up through a cupboard is definitely possible. I was wondering if it would better control my environment to just flow fresh air over the top of the tent above the lights. Aka have the In and out inline...

from tents to outside, air is drawn from my attic which isn't exactly sealed. weather is wet rightnow
