Hi guys.
Appologies if the Post is too long and thank you in advance if you look at my problem.
It's been a week since I'm looking all over internet , forums , search engine pictures redirecting to whatever possible source , websites for healthy plants but either I am ... retarded or th eproblems I'm facing are multiple or a combination of problems which makes it really hard for me to detect( I'm searching for an answer by myself from a long time ). Have some friends that are supposed to be marijuana gurus,but their answers doesn't seem to make any logic to me ( judging by the pictures I've seen online , my problems are not what they say ). I'm a second time grower . Previous time was 7-8 years ago with just one plant and no special care .I just chucked it in a wardrobe and that was it .So maybe I'm a first time grower anyway.
I have 3 major problems that might have various reasons to happen:
1. First some of the plants started to have yellow leaves ( bigger bottom one leaves ). Then after certain time the tips started becoming brown.
- Here I don't think it's a nitrogen deficiency because first I use nutrients and second i'm in flowering stage. Suspicion: maybe aphids , not good ph( high ) but I measured it few days ago was 6.8 , yesterday was 6.3-6.5 measured in the soil , 6.6 measured when collecting water from the bottom of the pot ( but maybe I'm not measuring it correctly ). Most of the times I've been feeding them with mineral water with ph 6.1 ( it's a quality water with dry residue of 135 ), other times I use tap water left for 2-3 hours open and then add white vinegar to lower the ph. Haven't seen any gnats but maybe have aphids ( not sure ). Or maybe root bounds , but yesterday I cut one of the pots ( on the side ) , didn't seem the roots were bound at all ( was expecting to see a net like from roots )
2. Some leaves started having some super small spots. Initially were white, but yesterday saw them as red/light brownish super small but a lot of them. On some plants even they start from the veins on the leaves.
- Really don't know what is this. Only similar thing was calcium deficiency, but my spots are small. Also don't wanna make a nute burn ( have stopped for a while because I some signs on one plant of a nute burn )
3. From yesterday I noticed black like spots on lower leaves and upper ones as well.
- I think this is because for the last days I panicked a lot and everyday was trying to clean the soil ( from excessive nutrients ) by adding water and throw away the excessive amount of water going out of the pot. I think this led to overwatering and some form of mold. But looking at the leaves they are not bent down like they are supposed to be if they were uner or overwatered. They are straight and looking towards the light. Another suspicion could be an iron deficiency ( but as I said ,not an expert )
Other people were telling me:
- heat stress: almost all of the time I was in the range 80-85F during veg and now I'm firmly holding 75-78F. Had some fans on/off each 15 mins ,but now ( 2 weeks ago I'm like when light is on fan is on , when off everything is off ). Humidity steady 40%. 3 fans in 2 out, and one kinda big for internal circulation.
- light stress: I use 2xhpsx250W. My box is strange because i upgraded it on the go. It's like one bigger 1.2x1.2mx1.8(height) attached ( with no internal walls ) to one smaller 1.2x0.6x1.8(h) box. Don't think the light is that much. Also if it was light stress the top leaves would be affected not middle and bottom ones.
I feel so desperate. Please help. I love my plants.
Really sorry for the long post , but I thought is better to explain it so you know better the preconditions.
Thanks
