Switching to led in veg. DTW coco.

[Cocopal]

Hello! I wanted to know if there is anything I should change in my feeding schedule.


I've been hand watering and now the roots have filled the pot. Is it ok at this point to water once a day with drippers like I always done ?


It does'nt dry like I'm used to under t-5's.


VPD chart says I'm good but humidity is much higher than I'm used to.


Also there seems to be a slight mag defiency something I've never seen using Jack's 3:2 I guess a small spray of Epsom salt might be in order. If I'm not mistaken, I think i read it could be common using leds ?



I picked up 2 Niello for a 4x4. https://www.amazon.ca/gp/product/B07NZLYNJL/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

i found that i needed to up my food about 20 to 25% with the LEDs...thats from using HPS before....also the LED color spectrum makes the plants use more CalMag...DJXX

Their is a terrific coco sticky thread. But, a couple quick rules with coco, feed every day and multiple times if possible. The only time you allow them to dry out is the first 7-10 days to allow for root growth.
No straight water, it washes out your cec.

multiple shorter feeds really shows the level of growth that can be attained in coco.

Thanks for your answers. I'm doing great with coco under 1000HPS feeding 5 times a day. The adjustment to led is a new thing.



I closed the light for a seaweed spray, they are pale green ! I could'nt see it with the lights on and wearing shades. They obviously lack some nutes.


I used to give my plants in veg. 500 ppm and everything was fine now I'll up to 700ppm it looks like it is the problem. I don't want to feed more than once a day in veg. it grows so fast I always end up choping the moms down !

I had to up my feed by about 40% from 1.1-1.2 EC to 1.5-1.6 EC. I also started adding Epson salts at about 1/4 teaspoon per gallon.

This is in coco feed once a day with Jack's 5-12-26 and Calcium Nitrate.

Thanks for your input. The extra mag seems to be omnipresent even with Jacks. Althoug in veg I'll see if it really needs it in a few weeks.

I had better results with 3/2.5. Dropped the epsom altogether. Stop by my coco thread and take a look. Good luck
