To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

Both, Water less but more frequently, next time mix for perlite into the medium so it won't have this issue. and feed less N in the irrigations. Good Luck!

Tips of leaves Curling upwards
3 days ago the Tips of the leaves, were Curling upwards and they still are Like that. Can this be a nutritional overflow? I meassured my EC and IT was at 1850 with the 5ml/L hesi Bio bloom. I give nutrients with every watering. Should i reduce the nutrients a bit to like 4ml/L?

Seedling leaves are discolored and starting to curl
Not sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!

Fan leaves curling up
Some of the fan leaves are curling up at the tips. Not all of the leaves just a few and only at the longest petal. Is this something I should be concerned about?

Discolored, burnt and curled up tips on higher leaves
Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?

Getting out of the ideas - VPD, nutrients or deficiency?
I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

leaves dry and curling up
Gelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches

While I wait for new pH meter give less liquid ferts (to avoid pH problems) start from 7.3 then don't know where it goes prob somewhere between 6.6/6.
Hi! Lower leaves=N def caused by flush prev week (due to build up), crispy yellow tips=P def? pH pen dead, watering blind, that's the main problem, using pH strips test.... 🤮 EC in 1.5 runout 1.9. Using Solid+liquid ferts (low dosage rn). Still stretching, looks healthy. Agree?

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Upward curling of leaves
One of my plants has started to have it's lower leaves curl upwards & started to go a yellow tint that's harder to see in my images. Yellow tint is starting higher up as well I think, but the curling is only on the low leaves. Is it nutrient defficiency, heat stress, wind stress?

Pointy Leaves and is it the light.
I read that the leaves begin to be thinner meaning blades as plant grows. The leaves are thinner and pointed otherwise plant growing has slowed but still reaching. Could my light be causing this because I am using both modes full spectrum?😳

Unhappy leaves
A few leaves aren’t looking too happy. What’s that? Deficiency’s, too much light, too many nutrients? It’s only a few leaves with that problems. What should I do, what would you do? Thank you!
