Before I start I should note I have been a fan of green crack for a while. Humboldt did great here. Seed sprouted next day, easy growing, and taking abuse like a champ (topped her a lot). Smell/quality is your typical green crack, although this was came out extremely frosty (even for GC). High is also what you would expect, good mood, focused, energized - awesome strain for day medication 👍 Absolutely recommended 👌
@BigDaddyK, @Mr_Di, it's definitely a N deficiency. I've try to warn this fellow a few weeks ago spotting the first symptom of a Mg deficiency meaning something was going wrong ....
I think it's over watering, what I was suspecting 3 weeks ago ....
@JUNGLE_B4RNS,
I'm adding calmag with every watering and nutes every 3 watering now. Yes the old growth is yellow but it will be trimmed anyway by the time tucking is done. New growth looks nice and green, dont know what else to tell:)
@BigDaddyK,
I agree. With the heat outside here in Cali my outdoor girls need water a lot more. Also because there is constant pressure from the tops, I can't just lift the pot to see if its light/dried out. I'm gonna give them 3 days without watering, and see how they'll respond. thanks
@BigDaddyK,
I give them shower every day until 5-10% runoff. I did neglected for too long with call mag which explains old growth yellowish, but new growth looks good.
If i grew your plant i would defoliate it a lot, now a lot of energy goes to the wrong place. The plant need a lot of air like the roots. And like the others say, go even lighter on the water. Your leafs is pointing down a little bit, so a think you can lower your led lamp a little closer to the plant. How far are the lamp from the top of plant? But i have to say one thing, im not a expert on growing and i never done a soilless grow.
I wish you good luck and happy growing.
@CBD_Sweden,yep strip some leaves and lower the light to penetrate through they grow back after about a week I will defoliate my photoperiods plants I did it three times on my stardawg grow twice in veg and a week in to flower obviously don't go crazy and don't worry about doing it they are very resilient good luck
I thing this bro...
1 for 9 week in coco, baby is too little.... (maybe low NPK ratio for me)
2 this kind of clorosis is: yellowing leaf not starting by edge (like mg def.), so i think soffer N deficency...
3 maybe over watering....so problem is there only on old leaf...I'm inclined to N deficiency and low npk ratio in general.
4 low low light power...maybe you bouth a led paragonated a 600w hps (that don't mean nothing, It is an act of faith towards the brand that produces them). What is you real led power? 300w?280w?
I'm here to collaborate!!
@Mr_Di,
I'm inclined to #4. Each plant is under a single 300w led (around 200w actual) and since sprouted I kept it as h as possible (making bigger canopy of light). I'll bring them down for a few days and see if it makes diff👍
you used 5 gal pots? those are freaking huge i was going to use my 7 gal filled all the way to the top but only filled time 3/4 or a little more i only have a 8x5FT grow space and 4 plants so i don't want to push it to hard.
@DrNovaCream,
Yeah just 5gal. I can't imagine her needing more space as she fills half of my tent pretty tightly. Perhaps outdoor would benefit more from <7 gal pot
These girls are finishing up fantastically buddy. Real top notch stuff here though I'd expect nothing less from you. Amazing buddy. I'm so excited to see these girls get harvested. I can't wait to see what you get from her and to hear the smoke report. Cheers!
DE, I believe your grows prove the axiom, ppm's should not exceed watts. Its hard to imagine you are feeding 150ppm because not many growers feed plants this minimally, but my guess is that you do.
Looking great, as usual. Congrats.
@Mr_Positivo, perhaps that's the case. I'm puzzled how so many can feed so much without burning their plants (I can spot minimal burn even at those low levels if they get to drink too much at a time). Tnx
