So I ran into some watering issues last week. Was able to get it sorted out.... This week presented a whole new batch of troubles as I will share with you all now! :) 11/6/20 - Plant leaves started to droop again. Hadn't watered in probably 4 days. Soil was again too dry. Realizing I need to water about a shot glass every other day in the solo cups. Gave them some water today, hopefully they'll perk back up tomorrow. Currently have 4 plants going. Plant 'C' is basically a lost cause but I'm going to keep her going for as long as she'll go! 11/7/20 - Plant leaves continued drooping, very confident I did not overwater them this time as I only gave about a shot glass each. Also noticed the first leaves on plant 'A' began to turn purple indicating nutrient deficiency. Unfortunately I don't have a pH or EC meter yet. Going to hang on for another day and see how they look. pH meter won't come in for a few days so I'd like to hold off on the first nute feed until it arrives 11/8/20 - Unfortunately I did not really take any pictures throughout the week. Starting today plants A, B, and C all have significant purpling of the leaves and the tips of plant 'A' are beginning to curl upward. Also noticed stems turning red. Note only applies to the lower level leaves on all plants, new growth up top still looks mighty green. Plants did perk back up a bit 11/9/20 - All 3 plants look an absolute mess. The lower leaves of all 3 plants are and cupping, curling and twisting all sorts of ways. Large portions of the leaf and especially leaf tips are turning necrotic. Most damage is purple in color w/ red stems. New growth at the top still looks "healthy". Definitely underestimated how quickly a nutrient deficiency would worsen lol. pH meter still not here so I'll have to do the first nute feed based on the feed chart and hope the pH isn't crazy high/low. -Grabbed 1 Gallon of water from the brook behind my house, let it come up to room temperature. Sure there might be some fish poo, pathogens, algae, etc., but I think I'm better off avoiding the tap due to the chlorine. Also like the idea of a natural source (as mother nature intended). Hoping I don't introduce any pests but my other houseplants have been drinking the stuff all year with no issue. Water should already have sufficient ca/mg due to the limestone rocks here in the northeast. TDS meter will hopefully be here soon to see where it's at -Using CX horticulture nutes from my local grow shop... Mixed the first gal at roughly 25% strength and avoided the "head masta" additive -Gave all 3 plants a shot glass worth 11/10/20 - damage to the lower leaves on all 3 plants continued to spread but definitely much slower and they've 'uncrinkled' a bit. Gave each another half a shot glass of nute mix 11/12/20 - Appears I've slowed down the damage considerably however large portions of the previously damaged leaves have died and turned crispy. Broke out the trimmers and tried to clean them up best as I could leaving as much leaf intact as possible. Plants are still growing strong up top and the purpling is still restricted to only the lower leaves. Planning on feeding another shot glass to each on 11/14/20 11/13/20 - lowered light to 24". Also notice slight yellowing around the ends of the leaves on plant A. Will continue to monitor
