Hello,
Im growing 4 Cheese and 4 Blue Cheese (blue cheese not affected) cuttings by Big Buddha Seeds, Scrog in a DWC system under 2 600w air cooled lights. Their in a 2.4 x 1.2 metre tent with a 700m3 extractor fan pulling air through a carbon filter and then pushing it through the lights and out of the tent. Passive intake. I'm using Canna's Aqua Flores A+B with their range of Additives, Just started the PK 13/14 this week. I'm now 3 days into the 5th week of flowring. 9-10 week flowering period. Nutes are changed every 7 days. I use tap water EC 0.4 and leave it in a 200L tank with a water pump circulating for 4-5 days before use. PH stays around 5.7-6.0 and I set the E.C to 1.4 at the start of the week and then it drops slowly as the week progresses. They're drinking around 2 litres of water a day each. Canopy temperature is 24-27 degrees celcius and humidity 60% in the canopy. Water temperature 18-19 degrees celcius.
The problem started Day 6 of week 4 flowering. I had to go away for a day, my nutes were down to EC 1.1 and EC 1.0 on the bigger plant and the weather warmed up outside causing the canopy teperature to rise to 32 degrees celcius. My light was 3 inches away from the top of canopy as it wasn't even and i wanted to get as much light to bottom of the canopy as i could. I got back and the leaves tips and edges were curling up, there was browning between the veins on the top half of the Cheese plants and the small leaves on the top buds on some colas had yellowed and curled down, mainly directly under the light hood. The blue cheese looked fine. I had my light 7 inches away from the canopy as it is even and hadn't stretched as much. The canopy temperature was 28 degrees celcius. I increased to power on the extractor fan and raised the light on the cheese plants to 10 inches from the canopy. I flushed the system with plain water PH downed to 5.8 and then put my nutes in as i had the week before only adding the PK 13/14 as the feed schedule suggests. Now 3 days later they're still drinking nutes, E.C 1.3 down from 1.4, PH 5.9 up from 5.8 and temperatures are fine.
I thought the light could have been to close and with the temperature rise that may have caused it but the Leaves on the Cheese plants are getting worse and I dont really no what to do. I've looked at loads of Deficiency pictures and problem solver charts but I still don't know what it is.
I hope there's enough information to help you and any help is appreciated. Thanks.
