ACTreeC started grow question 4 years ago
Wondering if someone could take a look at my plant. I think it was a bit hot yesterday, not sure if it is heat stress. Not sure if it is Nitrogen Toxicity either because of the dark leaves. Maybe this is normal? Can someone shed some light for me? Thanks!

This is your 1st grow?! It looks great. I see your slightly discolored tips, but in my opinion thats pretty common the further you go into flowering. If you're truly worried, then possibly flush and then add back the nutrients slowly, but i personally dont think you have too much to worry over. 7 weeks into flowering is pretty great, now she's just gonna plump up and color change...pistils etc.
Happy harvesting.:v:

@ACtreeC 1st off I love your name :joy: 2nd. I think this question has been substantially answered and is due for a close!

Generaly your baby looks ok. But still has two problems: first - you overwatering, as a result less cristals, less potency. Let them dry for a few days. When i watering i never let the solution run out. I water my plants 6 days a week, 1 day let them dry. Second you use tap water, thats for shure. How do i know it? Burning leaf tips. It's chlorine intoxication. Also using tap water and mineral nutrients increase the chance to get nutrient burn because of high TDS levels. As well there is a rule nomber ONE in agriculture: the lower TDS, - the higher uptake. My recomendation is to buy RO water filter. RO water has almost 0 TDS, so you can add more nutrients to your solution, without crossing the red line of TDS. And @Athos right buy your self EC/PPM(TDS) meter A.S.A.P.

Aint nothing wrong with your plant homie all i would do is clean her up a lil bit and keep doing wat u doing and btw its your low humidity causing your leaves to do that from wat i see

I see your running coco coir and perlite, also says your running just two nutrients. Micro and bloom. If this is correct then you are running my exact same setup, although mine is flood and drain, your just hand feeding with slightly less nutrients.

You should do a couple things here, you should be watering with a higher strength dose of the two your running. Micro should be ran at 8ml/gal and bloom at 16ml/gal. Your much too weak at this point in the game. Are you running tap water? If so try to find a city/municipality water reading, it may tell you the PPM of your water. I run around 200ppm from the tap, but I'd try to be below 250ppm otherwise you'll want to look for another source such as RO water.

Also id be looking at getting some calmag, if you get GH. For that you can run it at 4ml/gal and you can even go up to 6ml/gal.

You can do this all with out a EC pen,ive ran it multiple times with excellent results, no burn and no deficiencies. Flush 2 weeks, before harvest with straight water.

Also Change your Ph, run it around 5.8 - 6.0.

As for the heat stress maybe move the lights up 6 inch and see if that helps.

Leaves generally curl due to environmental reasons... plants reduce transpiration rates by covering the photosynthetic real estate with shadow. Intense light and heat cause water to transpire faster than the root system can take it up. If your light is truly 480W I'd move it up to 20-30cm instead of 15 in hot conditions.

Hi @ACTreeC! Well I think I see a purple stem (Phosphorous def), a [single?] burnt tip (Nitrogen toxicity), droopy leaves (overwatering) and curling-upward borders (heat stress) so there are many things that could go wrong in your medium/feedings, I can't even tell you where to start, but will take a look at your next update. Now as mentioned by others, the best way to ensure you're giving the right amount of nutrients is to get an EC-meter, otherwise you won't be able to maintain this plant healthy until harvest. Keep us up-to-date, and happy growing :facepunch:

Hello ! Your plant is green but not dark green , I won't bet on a N excess but you've got (slight) over feeding issue and I noticed that your Ph is 5.6 so you can start to increase the Ph level from 5.6 to 5.8 (5.8 ph is the hydro & coco sweet spot) , you should also take care of the water runoff Ph and EC as the output values are rarely the same than the input values. Your relative humidity is a bit low (45% is better in flowering) if you can reach it to 60% at least , it will be good. You need to get a Ec meter to know exactly what's going on with your feeding and to give her the right amount of nutrients ( the Ec is more reliable than the nutrients brand schedule). I hope it will help you :grin::+1:

Looks great, notice that some tips look burnt? That's because you are over feeding. Man, you can't grow soiless, without a EC/PPM meter. Get one, asap.
