Autoflowering plants' roots have grown too much and it's already flowering time


#1

Goedenavond dames en heren! I tell you about my case. I have four autoflowering plants growing in coco/perlite under led lights, they’re on their 3rd week of flowering, and I’ve noticed that even though there’s yet no sign of deficiencies suggesting they are root bound (the plants still look healthy) but the roots can be seen on the coco surface (when water splashes at watering them hitting the coco surface, though I do it gently, it removes some of the coco at the surface and thus the roots can be seen as a tangled mass on the surface). Also there are roots sneaking thru the drainage holes of the 11 liter plastic pots I’ve got them planted in. I suspected a problem after I obseved that the coco was drying too quickly and I needed to be constantly watering the substrate with about 1-1,5 L of fsolution per pot every one or two days (letting about 20% solution run-off each watering). During vegetative stage I used to feed them “heavily” once a week (following the Flower Power feeding schedule for soil) and every two days I watered with pH’d water only (ocassionaly I added Ca/Mg/Fe and Clean Drip to the water). In the flowering stage I’m feeding them “heavily” once a week and at 1/4 dose every watering time (every two days). The plants have responded well to this regime.
I am worried for this issue to decrease sitll further the yields I could have with autoflowering plants.
In a first instance I don’t think of transplanting at this stage for the few weeks more they have left.

Any suggestions/criticisms/recommendations, or whatever you might provide?

Best regards.

@gabarram,

sorry for the late response but you are doing a great job. At this point I would try to keep the roots covered over so that light can’t get to them. Ghen next grow I would go to much larger pots. I know I am that’s for sure.

Thank you very much for the guidance dear sir.
How much larger the pots? The ones I used are 11 L, do you say 20 L is OK or you’d try bigger ones?
By the way, the plants are heavily LSTed, do you think that along with a spongy substrate could have made the radicular system grow that much? I’ve grown auto’s in much smaller pots (7 L, in soil and no training at all) and I didn’t have this issue before.
