Hi Guys, I extremely need help.
I started a dripping system with clay pebbles only. Geopots of 7GAL full of clay pebbles only, one plant in each pot.
I made a dripping system by myself, looks ugly but delivers water to each pot (one plant per pot) independently.
I believe my problem is the watering schedule / amount of water I feed my plants with or any NUT feeding problems.
The water delivered to the pots drains continuously into the main reservoir (from where the same water is pumped to the plants). It is basically a closed loop. There is no water remaining on the bottom of the geopots I make sure the drainage gets rid of all the water at the bottom of the tray where the pots stand.
Every plant (fairly big now 30 cm high (indicas) has a ring with a few holes (3-4) from where the water drips, approximately each hole delivers 2-3 drops per second, (pretty high?). I was feeding 2 hours and 30 min sop, now I reduced to 45 min feeding and 30 min stop. I really need to know what is the best feeding time schedule, how many drops per second on each hole, and how many holes per plant please. Also do I need to stop the feeding, or I can feed for 18 hours of light continuously?
The plants were doing great for a while now a main issue seems to come up. Basically at the end of every light cycle (18 veg stage) I see leaves dropping, as curving down, really seems an over watering issue comparing the picture online. Also, The very last tip of the leaves is yellow (minor issue I think).
PH is reasonable, 5.8 and raise to 6.4 at the end of every cycle so I lower it down again.
EC increases as well, I add new water with CANNA nut (A+B VEGA) rizotonic and Cannazhym as per tables (I put a little less than 20ml/10liters for A - 20mil/10liters for B - 20mil/10liters for rizotonic and 25mil/10liters for cannazym).
The lights are placed 90cm / 1 meter above the tips of the plants, temp varies between 24 and 27 and humidity is a bit low between 40% and 65% (when lights are off increases).
